The eye has a clear lens located
behind the pupil that is responsible for focusing
light onto the retina in the back of the eye.
The clear lens normally gets somewhat cloudier
as time passes. Usually sometime after age 50,
the lens becomes cloudy enough that it significantly
effects vision. When the cloudiness has progressed
to this stage, the lens is called a cataract.
A cataract usually begins small and has little
effect on vision, but as it grows and clouds more
of the lens you may find that performing normal
tasks, such as reading and driving, become more
difficult. Symptoms of a cataract may include:
- Increased nearsightedness
- Sensitivity to light and glare, especially
while driving at night
- Blurred vision
- Distorted images in either eye
- Changes in the way you see colors, or colors
seem faded
- Cloudy, filmy or fuzzy vision
- Double vision
- Frequent changes in your eyeglass prescription
- Changes in the color of the pupil
- Poor night vision
- Cloudy lens at birth
Although researchers are learning more about
cataracts, no one understands exactly why the
eye's lens changes as we grow older.
