Sunglasses are for Everyone

Sunglasses should be on everyone. Every day, whether it is sunny or cloudy, no matter the season – we are exposed to ultraviolet radiation (UV) from the sun.  Most of the time, we aren’t even aware we are being bombarded with potentially damaging radiation (light). Just as the sun can damage your skin (burning, premature aging, and skin cancer) it also can have damaging effects in the eye.  There are two types of radiation in sunlight that affect the eye – UVA and UVB.  UVA exposure affects the lens in the eye and has been linked to a greatly increased chance of cataract development (a clouding of the lens of the eye).  UVB affects the retina and can cause severe damage. Furthermore, the damage from harmful UV radiation is cumulative over a person’s lifetime.  Because the damage is cumulative, it is important to protect your eyes every day, in all light conditions. So our children wil have the greatest risk of UV damage over their lifetime. Together with the AOA our office is on a mission to help inform the public that while theyoften selecting their sunglasses  because they look cool on and reflect their personality and/ or lifestyle there is more than meets the eye in a great pair of sunglasses. Sunglasses with the proper lens will help protect and preserve vision and often boost visual performance for your vavroite outdoor activities.
Sunglasses, with and without a prescription, that can block out nearly all UV light are readily available.  Eyeglass lenses with UV blocking characteristics protect the eyes and significantly reduce the chance of vision problems caused by sunlight.
Here are some important tips when considering lenses with UV protection (sunglasses):
  • Look for sunglasses that block at least 99% of ultraviolet rays, both UVA and UVB.
  • Lenses should be gray, green, or brown, and the larger the lenses, the better.  Wrap around sunglasses provide an extra measure of protection.
  • The best sunglasses are those purchased from an optometrist or optician.  This ensures the sunglasses have the appropriate amounts of filtering for both types of ultraviolet radiation (UV) and are the best protection for your eyes while in the sun.
  • UV light from the sun is harmful even in winter. Snowboarders and skiers should always wear tinted goggles, as UV light bounces off snow even on the cloudiest of days.
  • Sunglasses purchased from a department store or a street vendor may not provide important UV protection.  There is no assurance that eyewear, no matter how dark the lens, will protect against UV rays.
  • Polarized sun lenses are excellent at providing glare free vision, enhanced contrast vision, 100% UV protection, outstanding color perception, and reducing eye fatigue resulting from bright light conditions from the sun
  • New digital surface technology can inprove the quality of vision and eliminate peripheral distortion in sunglasses that are in prescription.
  • Back surface antireflective coatings reduce UV absorption due to reflected rays from back and side of lens.
Photochromic lenses (lenses that darken when exposed to UV light) are a good choice for an everyday lens because they automatically protect against UV.  However, it is important to recognize that not all plastic photochromic lenses block 100% of UV radiation.
Summer is almost upon us and due to the increase sunlight associated with our longer days, many individuals are thinking about the value of sunglasses.  If you are planning to purchase sunglasses, make the kind of selection in sun wear and lenses that will reduce the uncomfortable glare of bright sunlight, while providing you with the UV protection so important to your ocular health. So some patients ask what is the very best for my eyes ? A polorized polycarbonate lens that has a digital surface prescription, gray tint 50-80%, back surface anti-reflective coat and scratch coated finished  in a light weight frame that wraps to provide maximum protection for the eye.

An Eye Exam Can Save Your Vision from Glaucoma

Its estimated that about four million people in the United States have glaucoma, a group of eye diseases that damage the optic nerve and silently destroy eyesight. Nearly half of those with glaucoma are not even aware that they have it. So what about you? The number of cases that lose vision is unfortunate considering there are some high technology offices like Facchiano & Associates who maintain eye care offices with technology that can detect early signs of glaucoma long before that damage threatens vision. You owe it to yourself to find out your relative risk of lossing vision to glaucoma by getting a comprehensive dilated eye exam that includes having drops put in your eye and if the eye doctor orders extra diagnostics tests, an OCT optic nerve scan and threashold visual fields. With its painless and gradual loss of vision, glaucoma may have no early warning signs, but it can be detected during a comprehensive dilated eye exam.

Paul A. Sieving, M.D., Ph.D., director of the National Eye Institute (NEI), one of the National Institutes of Health, said, “NEI-funded research has shown that treatment during the early stages of glaucoma can control the disease and prevent future vision loss and blindness. This is why NEI encourages people at higher risk for glaucoma to get a comprehensive dilated eye exam every one to two years.”

Anyone can develop glaucoma, but those at higher risk for developing the disease include:
African Americans over age 40
Everyone over age 60, especially Mexican Americans
People with a family history of the disease

During a comprehensive dilated eye exam, an eye care professional can see inside the eye to detect signs of glaucoma, such as subtle changes to the optic nerve, before any symptoms appear. This allows the eye care professional to determine if you have glaucoma or are at risk for it, to monitor your condition, to treat glaucoma as early as possible, and to look for other vision problems. Once symptoms appear, it may be too late to prevent vision loss and the progression to blindness.

If glaucoma is detected early, treatments such as eye drops or surgery can slow or stop vision loss. High pressure inside the eye, which may be associated with glaucoma, does not by itself mean that you have glaucoma. Only a comprehensive dilated eye exam and evaluation of the optic nerve by an eye care professional can tell you that.

If you know someone at risk for glaucoma, let them know you care – schedule an eye exam with your eye care professional today.

Are digital high definition lenses right for me?

Amazingly sharp images with HD lens technology

Did you know that there are higher-order aberrations that can affect your vision, even if your prescription eyeglasses fully correct your special ophthalmic prescription needs? Well eye Drs have known for years that there are aberrations due to the optical characteristics of your eyes and often more from the optical limitations of conventional eyeglass lenses. The frustrating issue for an optometrist was that there was no ideal lens treatment or process that could either solve or reduce such aberrations. Drs knew many patients just did not see as well as they could but there was nothing Drs could due because of the limitations in eyeglass lens fabrication technology.

Times have changed now and recent advances in eyeglass lens manufacturing have made possible new high-definition digital eyeglass lenses that correct these aberrations, potentially giving a patient sharper vision than what was ever possible with conventional eyeglasses. These lenses are designed to provide sharper vision in all lighting conditions, provide wider progressive lens corridors, keep the prescription optically true over a much wider zone in the lens and reduce glare for nighttime driving and other night vision tasks.

Many brands of high-definition eyeglass lenses currently are available today, including high-definition versions of high-index lenses and progressive lenses.

Digital lens surfacing is six times more accurate than conventional lens processing because the new digital surfacing equipment uses less tooling and has direct contact with the lens enabling a high degree of accuracy. The analogy can be just like a digital camera. The higher pixal count yields a higher degree of resolution. When this happens as you have seen in your digital camera images, you get this amazing crisp image. So this is the same experience with the HD digital ophthalmic lenses today. The result is a very highly defined vision along with and unmatched depth and clarity never before possible. In the case of progressive addition lenses fabricated using the digital technology get ready for a refreshing change because of a 20% wider progressive field of view. From personal experience I know it makes for exceptional intermediate and near working ranges exceeding the conventional options. I am getting the benefit right now with my new digital lenses I am wearing. It really makes reading and computer use so much more comfortable and enjoyable; my eyes just get less tired with near visual tasks.

So wow! I can really appreciate the HD lenses wider, sharp and true optical zone and the crispness of detail is an awesome experience. You owe it to yourself to investigate this option the next time you fill your new eyeglass presciption.

Please ask your optometrist if these new lenses are right for your eyes.

Photoker-what?

Photokeratitis. This is the “sunburn” of the cornea. During the past 4th of July holiday were you out playing yard games with the family? Boating on the lake? Sunbathing on a beach? More importantly, were you wearing eye protection?

Sunbathing and Sunglasses

Sunglasses are beneficial to help prevent Photokeratitis. Symptoms may include discomfort, blurred vision, and light sensitivity. Many times the sunburn is not usually noticed until several hours after exposure. The temporary vision loss that may result from Photokeratitis is called “snow blindness.” Ultraviolet (UV) rays and excessive sunlight, especially the type of rays which bounce off of snow and ice may lead to this painful sunburn. Being knowledgeable in regards to UV light is important to protect your eyes.

Outdoor risk factors including geographic location, altitude, the time of day, setting, and medications all determine the risk of damage. UV levels are greater when the sun is high in the sky, typically from 10am to 2pm. Also UV levels are greater in wide open spaces, especially when highly reflective surfaces are present such as sand. Always be aware of your medications, birth control pills, sulfa drugs, and tranquilizers are a few of the medications that may increase your body’s sensitivity to UV radiation.

This “sunburn” of the eye is preventable by understanding what Photokeratitis is, how UV rays are harmful, and wearing sun protection. Sunglasses or eye protection that transmits 5-10% of visible light and absorbs almost all UV rays are most beneficial. Look for sun protection that has large lenses and side shields to avoid incidental exposure from light as well. Call your optician in Lenscrafters at (815) 332-3233 to discuss more options.

If you feel that you or a family member may have symptoms of Photokeratitis, please call Dr. Facchiano and Associates at (815) 332-2223 to schedule an appointment.

Can I sleep in my contacts?

Yes.. and no.

Sleep
There are two different types of contact lenses available daily wear (you remove them before sleeping) and extended wear (you leave them in overnight). The extended wear lenses allow for more oxygen to reach your cornea, thus making it more acceptable to be slept in. These lenses are typically allowed to be left in without removal for up to seven days.

The latest technology in contact lens material called silicone hydrogel, are approved by the FDA for up to 30 days of wear without removal. If interested, please consult your doctor about these lenses. “Continuous wear” lenses, also known as gas permeable lenses may also be worn for up to a month at a time. “After recent improvements in design and materials, these lenses now can be worn safely for the full 30 days for those who can tolerate them. Your optometrist will advise you about how your eyes are responding to extended wear and how frequently you should remove your lenses.”

So you’ve heard the “You’ll be more prone to eye infections if you leave your contacts in!” Well its true, researchers found that eye infections are greater among people who sleep with their contacts in. FDA has approved the maximum extended wear period to just seven days.

Our doctor’s still do not recommend leaving them in for a full seven-day period. Taking them out before you go to sleep will help decrease the chance of getting an eye infection significantly. Extended wear lenses are a concern for dangerous little organisms that start on your finger, may get on your contact, and then in your eye! These bacteria may lead to infections such as pink eye and in very serious conditions even blindness! If you feel you are having any problems with your contacts from extended wear, please consult with your Optometrist.

Sleeping in your contacts is possible with new silicone hydrogel lenses as they provide more oxygen to the eye than previous soft lenses. Although these materials make overnight wear safer, keep in mind the possibility for infections!

If you are interested in extended wear type contacts, please consult with your Optometrist at Dr. Facchiano and Associates. Call (815) 332-2223
