Cataract in simple terms is the clouding of the lens of the eye. A person with cataract would have a hazy and unclear vision. It is mostly related to aging, ie, as a person ages, the chances of cataract increase. Cataract can occur in one or both eyes.
If one has cataract, one may notice:
1) Cloudy, blurry or dim vision
2) Difficulty seeing at night
3) Sensitivity to light and glare
4) Fading or yellowing of colours
If one notices cloudy vision or other signs and symptoms of cataracts, a thorough eye examination is a must. The only effective treatment for cataracts is surgery. Medicines do not reduce cataract.
