Cataracts, Sensitivity to Light and Solar Shield ‘Fits Over’ Sunglasses

gardening fits ellaA cataract is a blurring of the lens in the eye making vision cloudy. Most cataracts are age-related. By age 80, more than 50% of all Americans will have a cataract.
The lens is a clear part of the eye that allows light (images) through to the retina. The retina is the tissue in the back of the eye. In a healthy eye, light passes through the lens to the retina, reaches the retina, is changed into nerve signals and these are sent to the brain. The lens must be clear for the retina to receive a sharp image. If the lens is cloudy from a cataract, the image you see will be blurry.
The eye lens is made of primarily of water and protein. The protein is arranged in a specific way that keeps the lens clear and lets light to pass through it. As we age, some of the protein may clump together and start to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens, making it harder to see.

There are many causes of cataracts such as smoking, diabetes, wear and tear and damage from exposure to sunlight (UV rays).

Cataract surgery consists of removing the natural lens of the eye and replacing it with an artificial lens (intraocular lens implant or IOL). After cataract surgery, many people experience some sensitivity to light. This is usually temporary. The crystal-clear material of the Intraocular Lens -IOL – nearly always allows more light to pass through than the natural lens it replaced, so some patients might have to adjust to seeing vivid colors and brighter lights than before surgery.

Most doctors recommend Solar Shield ‘fits over’ sunglasses which have excellent coverage and sunlight protection and they can be worn over eyeglasses or alone. They not only shield the eyes from direct light but also from light from above, the sides, angles and reflected light from the ground. In fact, more eye-doctors recommend Solar Shield ‘fits over’ sunglasses than any other brand of over-the-glass sunglasses.

Solar Shield ‘fits over’ sunglasses have a unique anatomy that makes them exceptional at preventing light from reaching the eye. Many styles have a top shield, side windows and a bottom shield to block light from all angles. The lenses are polarized to eliminate glare and offer 100% UVA/UVB protection. Best of all, they are designed to fit right over prescription glasses.

Why would you need an over-the-glass sunglass after cataract IOL surgery? Because most cataract surgery is performed one eye at a time. This means you will still need to wear your glasses until both eyes have had the procedure. The normal cataract process is to replace the lens that is most clouded first. If both are equally clouded, the doctor will usually replace the lens in the non-dominant eye first. The interval between surgeries depends on the healing of the first eye and the vision results; two to three weeks is typical. After the cataracts have been removed from both eyes and replaced by IOLs, you can still wear your Solar Shield sunglasses just like regular sunglasses. Solar Shield ‘fits over’ sunglasses are sold at virtually all mass retail and drug stores across the nation, and on-line at www.solarshield.com.
