A cataract is when the lens of the eye becomes cloudy. This prevents light passing through to the retina, which causes blurry vision. Usually cataracts occur as people age. Ultraviolet light, high blood pressure, diabetes, eye injuries, smoking, kidney disease, and certain medications are all contributors to the development of cataracts.
During routine eye exams, your optometrist will check for signs of cataracts. Early diagnosis is important to prevent any vision impairment that cataracts cause.
