A condition of the eye in which the lens of the eye becomes cloudy is called cataract. This causes vision to worsen, making it especially difficult to see fine details clearly. Some people’s vision is only slightly affected, whereas others might lose their eyesight very quickly. Its progression will depend on things like the exact type of cataract.
Cataracts mostly affect people over 50, and the risk increases with age: About 20 out of 100 people between the ages of 65 and 74 have a cataract.
