Cataracts affect more than half of people over the age of 65 and can usually be treated successfully with surgery. A cataract occurs when the lens of an eye becomes cloudy, and light cannot pass through it to get to the retina at the back of the eye. This results in blurred or dim vision, sometimes with a yellowish tinge. During your examination, your optometrist will check for signs of cataract and measure any deterioration in your eyesight. If necessary, your optometrist can refer you directly to an ophthalmologist for surgery to restore your eyesight.
