While a comprehensive eye examination can determine for certain if you have a cataract forming, there are a number of signs and symptoms that may indicate a cataract.
Among them are:
- Gradual blurring or hazy vision where colors may seem yellowed.
- The appearance of dark spots or shadows that seem to move when the eye moves.
- A tendency to become more nearsighted because of increasing density of the lens.
- Double vision in one eye only.
- A gradual loss of color vision.
- A stage where it is easier to see without glasses.
- The feeling of having a film over the eyes.
- An increased sensitivity to glare, especially at night.
What is a cataract?
A cataract is a clouding of the normally clear crystalline lens of the eye. This prevents the lens from properly focusing light on the retina at the back of the eye, resulting in a loss of vision. A cataract is not a film that grows over the surface of the eye, as is often commonly thought.
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.
