What Causes Double Vision?

Cataracts

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.
