Many individuals encounter cataracts as they age. In fact, they are one of the most common vision issues among individuals over fifty years old in the world. These imperfections are a condition of the eye's lens, which rests between the cornea and pupil. The job of the lens is to focus the light that passes through the cornea so a clear image hits the retina. This clear lens is made primarily of protein and water, and as individuals age, the protein can clump together into a cataract, causing a cloudy image. The distortion of the image can also lead to the ghost images of double vision. Fortunately, laser surgery can correct most cataracts.
