2. Genetics: Genetics is another cause of cataracts. Some people are predisposed to cataracts from birth, making them more prone to acquire the ailment.
3. Diabetes: People who have diabetes are more likely to acquire cataracts. High blood sugar levels can inflate the lens, causing cloudiness and visual loss.

6. Trauma: Cataracts can also be caused by ocular trauma. A hit to the eye can cause lens damage, resulting in cloudiness and visual loss.
7. Drugs: Some drugs, like steroids, have been linked to cataract formation. Long-term usage of these drugs may cause cloudiness and visual loss.
