In order to see well, many things need to work well including the visual command center in the brain, the nerves to and from the eye and of course the eye itself. One all too common condition  which affects vision is cataracts.

Cataracts, like many conditions, are much more common in older individuals. Good vision depends upon clear lenses. If the lens is cloudy, you won’t be able to see as well. Imagine a trying to see through dirty glasses or through a dirty windshield.

Vision is impaired especially at night, when lights reflect off the “dirty” lens are cause halos. Cataracts can be easily diagnosed, but eventually removal of the lens will be required. How to prevent cataracts is very important, since no one really wants surgery.

First and foremost, always wear sunglasses that block UVA and UVB rays, which are more energized and thus more harmful. If you live at higher altitudes and or are out in the snow a lot, you have a much greater exposure to such harmful ultraviolet light.  If you have diabetes, control your blood sugar. Hyperglycemia or elevated blood sugar, increases the risk of developing cataracts. Certain medications may increase cataract formation. Some diseases may also lead to cataract formation. You should check with your doctor to see if you have one of these risks.

It is important to have yearly eye examinations so that very early cataract formation can be detected. And don’t forget to wear those sunglasses, even if you’re only outside for a short time.
