Cataracts
Cataracts are a clouding of the eye’s natural clear lens, which transmits light and focuses it on the retina. Cataracts can occur at any age, but are typically found in older people as a natural part of aging. In fact, by age 65 most people have some cataract development that usually continues to progress.
There are, however, other causes of cataract: diabetes, trauma to the eye, excessive exposure to sunlight, inflammations and infections within the eye, certain medications, radiation, intense electric shock, smoking, poor nutrition, harmful chemicals, and others. 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.
