The leading cause of blindness is an eye disease such as cataracts, glaucoma or macular degeneration. Each can be slowed or treated through regular eye exams. On a daily basis, doctors recommend wearing sunglasses to guard against damage from the suns ultraviolet rays and using protective goggles during sports and certain household projects to protect against injury. See an ophthalmologist right away if you experience symptoms such as blurred vision, double vision, pain in the eye, redness, itching, swelling and seeing flashes of light or dark spots. Some of these, such as seeing spots, are signs of a serious condition, such as a detached retina. Less
