New Eye Color

A new eye color could be awaiting you. You are thinking though, those colored contact lenses always look so fake. When many considerations as well as type and design of lens are addressed, the new color can appear as real and natural as the original. There are more color options available than ever and these are also available in an extensive prescription range. One of the first and most important considerations is which color to choose. Not every color will look correct on every person. When you follow the appropriate guidelines you can really have a new eye color that enhances your appearance rather than turn you into an alien. This is of course unless you are trying to look like an alien! If your goal is to actually draw attention to your eyes, custom hand-painted lenses can be made with just about no restrictions other than your imagination. These hand-painted lenses grew from the need for prosthetic contact lenses (contact lenses that are something like a "glass eye" Whether it is a hand-painted one-of-a-kind lens or a very natural color that you are interested in, the lens color you are looking for is available today.

 

What Is A Cataract?

cataract \Cat"a*ract\, n
1: clouding of the natural lens of the eye
2: a steep descent of the water of a river [syn: waterfall}, {falls} {cascade}]
The lens is located behind the pupil, the black 'window' of the eye. A cataract causes the normally clear lens to become cloudy. This clouding prevents the lens from properly focusing light on the retina at the back of the eye, resulting in a loss of vision. Cataracts are most often found in persons over the age of 55, but they are also occasionally found in younger people, including newborns.

What causes cataracts?
Chemical change within the eye causes the lens to become cloudy. The change may be due to advancing age, heredity, injury, or disease, excessive exposure to ultraviolet or infrared radiation present in sunlight or from furnaces, and cigarette smoking. Certain medications are also cataract risk factors (more later).

Why are they called cataracts?
Sometimes cataracts can be seen as a milkiness on the normally black pupil. In ancient times, it was believed this cloudiness was caused by a waterfall - or cataract - behind the eye.

Some interesting facts about the lens and cataracts:
1. The lens consists of about 65% water.
2. There are no pain receptors, blood vessels, or nerves in the lens.
3. A cataract is not a film that grows over the surface of the eye.
4. Cataracts usually develop in both eyes, often at different rates.
