All About Vision

Prescription Sunglasses

Sunglasses are an important way to protect your eyes and ensure clear and comfortable vision when you are on the go. In addition to causing temporary vision loss, the sun’s bright rays can lead to long term eye damage. Ultraviolet radiation from the sun can also cause sunburns on the eyes and over time, can lead to diseases such as macular degeneration.

For those who wear prescription eyeglasses, sun protection is available in a number of options including prescription sunglasses, photochromic lenses or eyeglasses with clip-on sunglass lenses. The best solution depends on your personal preferences, comfort and which option fits in best with your lifestyle.

Prescription Sunglasses

These days, sunglasses are not only highly fashionable but remarkably functional for a wide variety of activities. Sport and athletic sunglasses for example provide eye protection, reduced glare and better contrast to improve performance in a range of outdoor conditions. Individuals with prescription eyewear can also benefit from the advantages of these specialty eyewear by purchasing prescription lenses.

Prescription sunglasses are available for virtually all vision prescriptions including those for farsightedness, nearsightedness and astigmatism, as well as bifocal and progressive lenses. Almost any pair of sunglasses can be fit with prescription lenses as long as the shape of the lens doesn’t distort vision (which happens for example with extremely wide wraparound lenses). Therefore if the latest pair of designer sunglasses catches your eye, there should be no problem in fitting a prescription lens to the frame.

You can also get prescription lenses in most lens materials and with most lens coatings, including polarized lenses (for glare protection), tinted lenses, anti-scratch coatings, polycarbonate or Trivex lenses (for extra durability) and more.

Even for those individuals who do wear contact lenses, prescription sunglasses are a fantastic solution when you prefer not to wear your contacts, such as when your eyes feel dry or irritated (during allergy season or in dusty or sandy locations for example), when you are going swimming (it’s advised not to wear contact lenses swimming in any body of water due to risk of infection) or when you just don’t want to deal with the hassle of contacts. Prescription sunglasses give you yet another option for comfort, safety and great vision.

Photochromic Lenses

Photochromic lenses are another alternative for the prescription eyeglass wearer. These lenses darken in response to sunlight turning your regular prescription eyewear into prescription sunglasses. Photochromic lenses are a convenient solution for glasses wearers who find it a hassle to carry around two pairs of glasses. No matter what shape or style, you can protect your eyes and spruce up your outdoor look or your sports performance with a pair of prescription sunglasses.

Pingueculae & Pterygia

Pingueculae and Pterygia are both benign growths that develop on the surface of the eye. While often grouped together, there are some differences in expression, symptoms, causes and treatment so here is an explanation of each condition and the differences between them.

Pinguecula

Pingueculae (pinguecula in singular) are growths that occur on the conjunctiva or the thin clear layer that covers the white part of the eye known as the sclera. They can be diagnosed on patients of any age, but tend to be more common in middle age. Pingueculae are typically yellowish in color and appear as a small, raised, sometimes triangular protrusion close to the cornea.

Causes of Pinguecula

Pinguecula occur when bumps, typically containing fat and/or calcium, form on the tissue of the conjunctiva. The exact cause of pinguecula is not known but there is a correlation between unprotected exposure to sunlight, wind, excessive dryness and dust.

Symptoms of Pinguecula

Pingueculae may have no symptoms or they can cause feelings of dryness, irritation or feeling like there is a foreign body in your eye. In more severe cases they may become itchy, inflamed, red and sore.

Treatment of Pinguecula

Often, there is no treatment necessary other than to protect the eye from the sun and other elements. If however, the pinguecula is causing discomfort or other issues, there are treatments available depending on the symptoms. Dryness, irritation and itchiness can sometimes be treated with eye drops or ointment and in cases where there is swelling, steroid eye drops along with anti-inflammatory medication may be prescribed. In rare cases that the pinguecula is causing serious problems such as vision problems, untreatable discomfort or preventing blinking, or the patient is unhappy with the way it looks, it may have to be removed surgically.

Pytergia

Pytergia (pytergium in singular) are wedge-shaped growths on the surface of the cornea (the sclera), made of fibrous conjunctival tissue and containing blood vessels, which sometimes make it appear pink. Pytergia often grow out of pinguecula and tend to be more visible.

Causes of Pytergia

Like pinguecula, pytergia are believed to be caused by extended exposure to UV rays from the sun and are sometimes called “surfer’s eye”. They are more common in adults (ages 20 – 50) who live in dry, sunny climates and spend significant time outdoors. Risks increase in those who do not properly protect their eyes by using sunglasses and hats when they are outdoors.

Symptoms of Pytergia

Pytergia may occur in one or both eyes and usually grow in the corner of the eye closest to the nose in toward the cornea. Very often there are no symptoms however some people may experience dry eyes, redness, irritation, the feeling that something is in their eye and inflammation. Pytergia may also cause discomfort for contact lense wearers. If the pytergium is serious it could grow far enough into the cornea to obstruct vision or cause the cornea to change shape resulting in astigmatism.

Treatment for Pytergia

If necessary, treatment for symptoms of pytergia may be similar to those used for pytergia such as lubricating eye drops or steroidal drops or creams to reduce inflammation. Surgery is more common for pytergia because of the more obvious change in appearance and because of the potential for vision disturbances. Sometimes a conjunctival graft is performed to prevent recurrence which is when a small piece of tissue is grafted onto the area where the pytergia was removed.

Pytergia and pingueculae are often completely benign conditions but should be monitored by a doctor to ensure they do not get worse and pose a threat to vision. Nevertheless, these growths go to show how important it is to protect your eyes from the harmful UV rays of the sun.

Surgery for Presbyopia

Presbyopia is a common age-related condition in which near vision worsens due to the hardening of the lens of our eye. It causes people to have difficulty reading and performing other tasks that require sharp and focused close vision.

Symptoms begin around the age of 40 when you begin to see people with untreated presbyopia holding books, magazines, newspapers, and menus at arm’s length in order to focus properly and avoid eye strain. Other symptoms include headaches or fatigue when trying to focus on something at close range.

Causes of Presbyopia

During our youth, the lens of our eye and the muscles that control it are flexible and soft, allowing us to focus on close objects and shift focus from close to distant objects without difficulty. As the eye ages however, both the lens and the muscle fibers begin to harden, making near vision a greater challenge.

Surgical Treatment for Presbyopia

The most common form of treatment for presbyopia is wearing reading glasses, bifocals or progressive lenses. Bifocal and multifocals are also available in contact lenses for those who prefer to be glasses-free. A third option, however, is a number of surgical procedures that allow you the freedom of correcting your near vision without the use of glasses or contact lenses.

LASIK

Monovision LASIK

Monovision is a technique that began with presbyopia-correcting contact lenses designed for individuals with presbyopia and nearsightedness or astigmatism. Each eye gets a different lens power – one lens is used in the dominant eye to correct for distance vision and the other for near vision. The eyes adapt to the two lens powers by learning to use the appropriate eye for the necessary distance power. Monovision LASIK surgery is based on the same principle of correcting each eye for a different refractive power and has shown just as high if not higher success rates than the contact lens technique. Usually, patients will try out monovision with contacts first to ensure that it works and that the eyes adapt properly.

PresbyLASIK

PresbyLASIK is a procedure that is currently available in Canada and Europe and undergoing clinical trials in the United States. As opposed to monovision LASIK, this procedure is a multifocal alternative in which different rings of refractive power are created on the cornea, similar to multifocal lenses. This provides vision correction at all distances simultaneously.

Conductive Keratoplasty (CK)

Conductive Keratoplasty uses radio waves via a hand-held instrument to mold the corneal surface to improve near vision. The procedure can be done on one eye using the monovision principle and is a good solution for those that do not need vision correction for nearsightedness or astigmatism. The effects of CK, however are not permanent and the improvement in near vision will diminish over time.

Corneal Inlays or Onlays

Corneal inlays and onlays involve surgically implanting a small lens into the eye to increase focus and near vision. The distinction between inlays and onlays is in where the lens is placed on the eye.

Refractive Lens Exchange

In refractive lens exchange the eye’s hardened lens is replaced with an artificial lens called an intraocular lens (IOL) to provide multifocal vision. This surgery is similar to and often done in conjunction with cataract surgery.

Treatment of Macular Degeneration

While there is no cure for macular degeneration, treatments do exist that can delay the progression of the disease, preserve existing vision and sometimes even improve vision loss.

Currently, there are no approved treatments to prevent or cure dry AMD, although there is evidence that indicates that certain nutritional supplements, including omega 3 fatty acids, lutein and zeaxanthin, can prevent the progression of the disease to the more advanced wet form, which can cause more severe vision loss.

There are a couple of options for treating wet AMD to slow the progression of vision loss which include medicated injections and laser therapy. These therapies are designed to stop the development of new blood vessels, to destroy existing ones and to prevent leakage into the macula – the main dangers with wet AMD.

Unfortunately, while much research continues to be conducted, currently there is no treatment and no way to fully regain vision lost by AMD. Those who have suffered significant vision loss can benefit from the many low vision devices on the market which utilize your existing vision to assist in maintaining your independence. Such devices include standing and hand-held magnifiers and telescopes and other aides that can help to improve your vision.

If you have been diagnosed with AMD, regular vision tests are essential. Close monitoring and adherence to treatment can not only prevent further vision deterioration but can sometimes even improve vision.

Lens Options for Eyeglasses

If you thought the trickiest part of choosing a new pair of glasses was the frame selection, think again. You should be putting just as much thought and consideration into the lenses that you select for your new specs.

Here’s why:
The quality and type of lenses in your eyeglasses will not only correct your visual acuity, but they will allow you to continue to see your best through various conditions. Whether it is keeping the lenses free from scratches, fog, glare or UV rays, or making them stronger or more attractive, your eyeglass lenses can help to keep your eyes safe and comfortable wherever the day (or night) takes you.

Lens Coatings

Here are a variety of coatings that you can apply to your lenses to maintain optimal vision and comfort and to protect your lenses and your eyes.

Anti-reflective/Anti-glare Coatings

Anti-reflective (AR) also known as anti-glare coatings help reduce the reflections and glare on your lenses, improving your vision and comfort in high-glare environments, and the look of your glasses as well (you can see your eyes clearly without a reflection on the front of the lens). Reflections from the sun, television and computer screens and bright lights (especially when driving at night) can cause eye strain, headaches and difficulty seeing. AR coatings and lenses can reduce this effect, improving your vision quality and comfort in these circumstances.

Scratch Resistant Coatings

Scratches not only affect the smooth look of the surface of your glasses but they can disrupt your vision. A scratch-resistant coating adds an extra layer of protection on the surface of the lens to significantly reduce scratching. This coating is particularly great for kids who may tend to be a little more rough with their eyewear.

Ultraviolet Coatings

Ultraviolet (UV) coatings protect your eyes from harmful UV rays from the sun. This coating can turn standard lenses into UV blocking lenses that can block 100% of the UV light from entering your eyes. UV is linked to the development of a number of eye diseases such as cataracts, macular degeneration and retinal damage.

Anti-fog Coatings

Particularly if you live in a cold climate, you may have experienced walking indoors from the cold and having your glasses lenses fog up completely. This can take a few minutes to resolve and can be dangerous if you are driving or need to see clearly. Anti-fog coatings will eliminate this effect, creating a smooth transition from cold to hot environments.

Lens Options

You may want to go with an upgraded lens to improve the look, strength or functionality of your glasses.

High Index Lenses

High index lenses have a higher refractive index which means they reflect more light than standard prescription lenses. What this means for you, the consumer, is that they can be made thinner and lighter than traditional lenses. High index lenses are particularly popular with those that need a high prescription as they are able to avoid thick lenses, adding comfort and a smoother look, but a higher price tag.

Trivex or Polycarbonate Lenses

Trivex or polycarbonate lenses are impact resistant lenses – a fantastic choice for sports and safety eyewear as well as standard sunglasses and eyeglasses for active types or kids. These lenses also offer full UV protection and are lightweight for optimal comfort.

Polychromatic Lenses

Polychromatic lenses are made with special technology that turns them into sunglasses when exposed to sunlight. The lenses darken automatically when you go outside and return to normal when you go back indoors. Polychromatic lenses can come in a number of tint colors and are great when you need prescription sunglasses but don’t want to carry around or pay for another pair.

Aspheric Lenses

Aspheric lenses use advanced technology to create a slimmer, flatter and lighter lens than standard prescription lenses. While aspheric lenses can improve the appearance of any prescription lens, they are especially beneficial for those who are farsighted since those lenses tend to bulge out in the middle.

So the next time you are in the market for new eyeglasses, speak to your optometrist or optician about the best lens choices for your eyes, your vision and your lifestyle.

Nonprescription Sunglasses

Everyone should have a good pair of sunglasses. Whether you wear prescription eyeglasses or not, sunglasses are important for every age, race and gender. While sunglasses may be considered a must-have fashion accessory, even more importantly, they play a critical role in protecting your eyes from UV (ultraviolet) and other harmful radiation from the sun. They also shield your eyes from wind, dust and debris that could cause discomfort, dryness or damage.

Sunglasses should be worn in the winter as well as the summer and should be 100% UV blocking. This doesn’t mean that you have to pay a fortune for your shades. Even cheaper brands of sunglasses are made these days with full UV protection, so take the extra time to ensure you select ones that do offer full protection from the sun’s rays.

Frame Materials

Sunglass frames are made in a wide variety of materials from plastics and acetates, to wood and natural materials to metals, such as aluminum, steel or titanium. Before you select a pair of frames, think about your lifestyle and what type of material will be most suitable for you. If you live an active lifestyle, sturdy and durable frames are a must. If you have sensitive skin, look for a pair made with hypoallergenic material that is light and fits comfortably. Make sure you select a pair that fits well, looks good and properly blocks the sun to ensure that you feel confident and comfortable when you are wearing them.

Sunglasses Shapes

Sunglasses serve as a combination of function and fashion and therefore come in a plethora of shapes and styles. Sunglasses are often larger than eyeglasses to cover more surface area and prevent sunlight from entering around the lenses. While fashion sunglasses are made in all of the latest styles from aviator to cat eyes, round, square and oversized, sports sunglasses are generally more durable and broad, often in wraparound styles that prevent sunlight from entering from the sides as well. Wrap-around frames are a good option for athletes, fishermen and bikers that spend a lot of time outdoors in the sun.

Lenses

Lenses are the most important part of any pair of sunglasses. As mentioned above, all lenses should block 100% UV rays but beyond that there are many options for sunglass lenses. Polycarbonate or trivex lenses are impact-resistant to increase safety during sports and outdoor activities. Polarized lenses help to reduce glare and are particularly helpful during activities on or near the water such as boating, fishing or beaching. Anti-glare and anti-scratch coatings are also beneficial to maintain your best vision in a variety of conditions.

For the fashion conscious there are a number of colors and reflective coatings available for sunglass lenses. It’s best to choose the lenses that allow for the most accurate color vision with the least amount of distortion to ensure they don’t obstruct clear vision.

While it’s important to choose sunglasses that you like from a style and appearance perspective, it’s also important to pay attention to comfort and fit. Here are a few tips for purchasing sunglasses that fit well for maximum comfort and sun protection:

  1. Make sure the lenses completely cover your eyes and provide extra coverage above and to the sides.
  2. The frames shouldn’t pinch at your temples or the nosepiece and should be wide enough for your face.
  3. Ensure that the frames aren’t too wide and stay in place when you move your head around.

Sunglasses for Prescription Eyeglass Users

If you wear prescription eyeglasses there are a number of options for sun protection. These options include prescription sunglasses, photochromic lenses (which turn from clear lenses to dark when you go outside), clip-ons, fitovers (which are sunglasses that go over your prescription eyewear) or wearing contact lenses with plano (non-prescription) sunglasses. Speak to your optician to determine the best option for you.

Photophobia

All types of light, ranging from interior lighting fixtures to streetlights and to the bright rays of the sun, have the potential to cause eye discomfort or pain. Photophobia refers to this ocular sensitivity to light.

An eye irritation or infection may cause photophobia. Other culprits include albinism, migraines, recent eye surgery or a variety of vision problems. In rare incidences, a congenital disease or certain medications may increase your sensitivity to light. The retina, which is the light-sensitive tissue at the back of your eye, is responsible for processing images. Treatment for photophobia involves treating the underlying cause that is disturbing the retina.

With light-sensitivity, the retina sends signals to the brain that are interpreted as discomfort or pain. The level of discomfort is in direct proportion with the strength of the light source, and it doesn’t matter if the light is man-made or natural.

Signs of Photophobia

When exposed to bright light, symptoms of itching, burning, wincing and squinting may all be experienced. Excessive tear production is another sign of photophobia.

Diagnosis and Treatment

If you suffer from light-sensitivity, you should schedule a consultation with your eye care professional.

People with lighter-colored eyes generally have more of a tendency towards photophobia, and intense light is likely to bother them. If you have light eyes, the lower quantity of pigment is less efficient at diffusing the light beams.

Photophobia may be temporary, or it can appear as a permanent side-effect of an underlying eye condition. The only way to treat photophobia is therefore to get to the root of the problem with a comprehensive eye exam. It’s important to mention any current medications to your eye doctor, as they may be associated with photophobia.

PRK

Photorefractive Keratectomy or PRK is a type of refractive laser eye surgery used to correct a patient’s vision to eliminate or reduce their dependence on glasses or contact lenses. PRK is the style of laser eye surgery that preceded LASIK, having been the former most common type of refractive surgery until LASIK came along.

PRK is effective in correcting nearsightedness (myopia), farsightedness (hyperopia) and astigmatism and has very similar rates of success and outcomes as LASIK. PRK remains a common option for laser eye surgery.

How Does PRK Differ From LASIK

PRK and LASIK both permanently reshape the cornea to improve vision by using a laser (an excimer laser to be exact) to remove part of the tissue underneath the corneal epithelium. The epithelium first needs to be removed in order to get access to the tissue and how this is done is what differentiates the two procedures. While LASIK creates and lifts a flap on the outer corneal layer, reshapes the corneal tissue underneath and then replaces the flap, PRK removes the outer layer of the cornea completely. The outer layer will regenerate usually within a few days.

Advantages of PRK

Since PRK completely removes the outer corneal layer, there is a greater area of the cornea to work with. This is ideal for patients with a thin cornea who would otherwise be at risk with LASIK. It is also usually recommended for patients with chronic dry eyes. With PRK, there is also less risk of infection or issues having to do with the flap and the related healing process. This is an advantage for individuals who lead a lifestyle in which they are at risk for eye injuries (athletes, military, law enforcement etc.) which may subject the flap to injury or complications.

So, Why Is LASIK More Popular?

The main advantages that LASIK has over PRK are two-fold and mainly have to do with comfort and recovery time. First of all, PRK patients usually experience slightly more discomfort during the first couple of days of recovery, mainly because it takes time for the outer corneal layer to heal. They will be prescribed eye drops to be taken for several months to prevent infection, increase comfort and assist the healing process. LASIK patients on the other hand, typically experience less discomfort and if they do, it subsides very quickly.

Additionally, vision recovery takes longer with PRK. While LASIK patients can typically see normally within a few hours after the surgery, with vision gradually continuing to improve within the next few months, PRK patients may experience blurred vision for up to three days and it can take up to six months until they achieve full visual clarity. While patients who undergo LASIK can usually drive and resume normal functioning within a day or two, PRK patients shouldn’t plan on returning to normal for at least several days until the outer layer of the cornea has grown back.

Whether PRK or LASIK is a better option for you depends on a number of factors, including the health and structure of your eye. This is a decision that your eye doctor or surgeon will help you make. Rest assured however, that both procedures have been shown to be incredibly successful in correcting vision, with minimal complications.

What You Need to Know About PRK

Prior to any laser correction surgery, you will meet with a surgeon for a thorough exam to assess your eye health and determine whether you are a candidate and if so, which type of surgery would be best suited to your needs. During this exam it is essential to tell the doctor any relevant medical history (injuries, hospitalizations, diseases etc.) and existing conditions you have. The surgeon will determine if you are currently eligible for surgery and if not, if you will be at a future point, and whether you require any specialized care pre or post surgery.

The surgery itself is an ambulatory procedure. It takes about 15 minutes or less for both eyes and you go home the same day. You will need someone to drive you home from the procedure.

The first step in the procedure is that your eye will be anesthetized using numbing eye drops and then a device will be inserted to prop your eyelids open so you won’t blink. Once the eye is numb, the surgeon will remove the outer epithelial layer of the cornea to expose the underlying tissue. Then the surgeon will use the laser to reshape the corneal tissue. You may feel a small amount of pressure during this step. Lastly, the surgeon will apply medicated eye drops and place a temporary contact lens that is used as a bandage to protect the eye.

Following the surgery you will be instructed to apply medicated eye drops multiple times each day to reduce the risk of infection and you may also be given prescription pain relievers to alleviate any pain or discomfort.

As with any type of surgery, it is critical to carefully follow your surgeon’s instructions after PRK. Make sure that you take your medication as prescribed, get enough rest, and call your eye doctor immediately if you experience any problems.

It is normal for it to take several days or even weeks for your vision to improve and up to 3-6 months for full recovery to clear and stable visual acuity. Usually, your doctor will require you to refrain from driving for a week and up to three weeks depending on how fast your vision recovers.

Risks and Complications of PRK

While serious complications are rare, like any surgery, there are some risks to PRK, and these happen to be very similar to any laser corrective surgery like LASIK. They include:

  • Dry eyes- this condition usually goes away within a couple of months, but there is a chance that it could become chronic.
  • Infection or Inflammation- the risk of infection is greatly reduced if you take proper care to follow your doctor’s instructions following the procedure.
  • Vision Problems- which can include glare, seeing halos around lights poor night vision and sometimes a general haziness.
  • Incomplete Vision Correction – sometimes an additional procedure might be needed to achieve optimal visual acuity.

In general, PRK is considered to be a relatively safe and effective treatment for vision correction. If you wish to live a life without depending on your glasses or contact lenses, speak to your eye doctor about whether PRK is an option for you.

Symptoms & Risk Factors of Macular Degeneration

Macular Degeneration can cause low vision and debilitating vision loss, even blindness if not diagnosed and treated in the early stages. Because the disease often has no obvious symptoms early on, it is critical to have regular comprehensive eye exams, particularly if you are at risk.

Symptoms of AMD

Macular degeneration is a disease in which the macula slowly breaks down, resulting in a gradual progressive vision loss, at least in its’ early stages. Frequently there are no symptoms and the disease is only diagnosed when a doctor detects signs such as a thinning macula or the presence of drusen in a comprehensive eye examination. Early vision loss can include blurry, cloudy or distorted central vision or dark spots in your central field of view. With advanced stages, vision loss can be severe and sudden with larger blind spots and total loss of central vision.

Risk Factors for Macular Degeneration

Age is the most prominent risk factor for AMD, as the disease is most common in individuals over the age of 60 (although it can happen in younger individuals as well). Other risk factors can increase your chances of developing the disease such as:

  • Genetics and Family History: Research shows that there are actually almost 20 genes that have been linked to AMD, and they suspect that there are many more genetic factors to be discovered. Family history greatly increases your chances of developing AMD.
  • Race: Caucasians are more likely to get AMD than Hispanics or African-Americans.
  • Smoking: Cigarette smoking can double your likelihood of developing AMD.
  • Lifestyle: Research shows that UV exposure, poor nutrition, high blood pressure, obesity and a sedentary lifestyle can also be contributing factors.
  • Gender: Females have a higher incidence of AMD than males.
  • Medications: Certain medications may increase the chances of developing AMD.

To reduce your risks of developing AMD it is recommended to make healthy choices such as:

    • Regular eye exams; once a year especially if you are 50 or over.
    • Stop smoking.
    • Know your family history and inform your eye doctor.

 

  • Proper nutrition and regular exercise: Research indicates that a healthy diet rich in “Eyefoods” with key nutrients for the eyes such as orange peppers, kale and spinach as well as regular exercise may reduce your risks or slow the progression of AMD.
  • Maintain healthy cholesterol levels and blood pressure.
  • Dietary supplements: Studies by the National Eye Institute called AREDs and ARED2 indicated that a high dosage of supplements of zinc, vitamin C, vitamin E and lutein may slow the progression of advanced dry AMD (it is not recommended for those without AMD or early AMD). Speak to a doctor before taking these supplements because there may be associated risks involved.
  • Wear 99% -100% UV-blocking sunglasses.

 

The first step to eye health is awareness. By knowing your risk, taking preventative measures and visiting your eye doctor on a regular basis, you can greatly reduce your chances of facing this debilitating disease.

Suggestions For Age-Related Vision Loss

Age-related vision difficulties and vision loss can be a challenge, but there are many solutions to help you cope and lessen the impact it can have on your daily life. Simple strategies from getting the right pair of glasses, to improving lighting, to purchasing some vision aids or magnifiers, can significantly help to compensate for reduced vision. Vision changes are normal with age yet it’s important to speak to your eye doctor so you know what to expect and ensure that the changes you are experiencing are normal and not a sign of a more serious eye or vision condition.

Normal age-related vision changes include reduced near vision (presbyopia), trouble seeing in dim light (due to the pupil shrinking and letting less light into the eye) and difficulty driving at night. Additionally, color vision and contrast sensitivity may be reduced. Most of these issues can be corrected with the right pair of eyeglasses to increase visual acuity and contrast and reduce glare. Improving lighting conditions within the home and office can also help. You may want to purchase some good portable lamps to brighten work spaces, especially when you are reading or performing fine motor skills such as typing, painting or sewing.

Cataracts is a common age-related condition in which vision is gradually reduced due to a clouding of the lens of the eye. When it begins to seriously affect vision, a surgical procedure to remove the lens and replace it with a clear artificial lens can be done. This procedure is extremely common and typically very successful in restoring vision.

Options for Permanent Vision Loss

Age related and other eye diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy can result in permanent vision loss or blind spots. This results in a condition called low vision, in which some vision remains, but the quality is compromised. This can be devastating for many people that are used to living independently but suddenly require a lot of assistance for daily living.

Thankfully, there are many products out there to help individuals with low vision manage daily tasks without assistance and the technology is always improving.

Some examples include:

  • Hand held and stand magnifiers, some with lights included
  • Large screen televisions and computer screens
  • Phones and other devices with larger numbers or fonts
  • Lenses and shields to reduce glare on screens
  • Screen reader programs and wearable devices

The most important thing you can do to preserve your vision as you age is to schedule regular eye exams. Many vision-threatening diseases only begin to show symptoms when vision loss has already begun and may not be able to be restored. A thorough eye exam can detect early signs of disease and allow for treatment and preventative measures to reduce vision loss. As you begin to notice changes you should schedule regular exams to monitor your eyes and vision and to rule out any serious diseases that could cause irreparable vision loss.
