Characteristics of Cataract:
(i) Eye sight becomes foggy
(ii) Eye lens becomes cloudy
(iii) There is a loss of vision
Explanation:
Cataract is an eye disease characterized by the clouding of the eye lens, leading to a gradual loss of vision. Let's understand each characteristic in detail:
(i) Eye sight becomes foggy:
In the initial stages of cataract, individuals may experience a foggy or blurry vision. They may find it difficult to see objects clearly, as if looking through a foggy window. This fogginess occurs due to the clouding of the eye lens, which prevents light from passing through clearly.
(ii) Eye lens becomes cloudy:
Cataract occurs when proteins in the eye lens clump together, causing it to become cloudy. The lens is normally transparent and helps to focus light onto the retina at the back of the eye. However, with cataract, the cloudiness of the lens hinders the passage of light, resulting in impaired vision.
(iii) There is a loss of vision:
As the cataract progresses, the loss of vision becomes more pronounced. The clouded lens prevents a clear image from forming on the retina, leading to decreased visual acuity. This loss of vision can impact daily activities and may require corrective measures such as glasses or surgery to restore clear vision.
Conclusion:
Cataract is a common eye disease characterized by a foggy vision, clouding of the eye lens, and a gradual loss of vision. It is important to seek medical attention if any of these symptoms occur, as early detection and treatment can help prevent further deterioration of vision.
