Obtaining a correct prescription from your doctor is the first important step in seeing well, but not the last. Selecting the right lenses for your glasses is a critical and yet poorly understood factor. This is especially true for seniors, patients who spend lots of time on computers, sports enthusiasts and those with certain eye diseases.
Prescription Lenses
Seniors aged 65 need about six times the amount of light to see as well as a twenty year old due to various changes in the cornea, lens and retina. A normal untreated plastic lens loses about 8% of light due to reflections and a high-index lens loses about 12%. The only way to combat this loss of light is with anti-reflective (AR) coats, which increase transmission to about 99%. The best AR coats have built-in warranted scratch coats, which provide a type of insurance on the lenses against scratching. Seniors are also more sensitive to glare, which may be annoying or incapacitating. This problem is dealt with by utilizing photochromic lenses that change color or with separate polarized sunglasses. Even the color of the tint will affect the vision in different environments.
