It is normal for the natural lens of the eye to develop into a cataract. Other causes of cataract include:
- Trauma to the eye
- Excessive exposure to sunlight
- Inflammations and infections within the eye
- Certain medications
- Intense electric shock
- Poor nutrition
- Harmful chemicals
Cataracts can also be congenital or develop prematurely in younger people.
Because cataracts form slowly over time, many people assume that their vision is simply becoming fuzzy or blurry as a natural part of getting older. If you’re noticing that road signs, people’s faces at a distance, or even TV images appear unclear, you may be experiencing symptoms of cataracts. Things may also appear as if you’re looking through a dirty window. Diminished night vision, glare, and halos around lights could also indicate the development of cataracts.
Regular eye exams, especially for those over age 40, can easily detect the formation of cataracts. Cataracts are treatable and options vary.
