“More than half of all Americans age 80 or older either have cataracts or have had surgery to remove cataracts, according to the National Eye Institute (NEI). The Centers for Disease Control and Prevention (CDC) states that cataract is the leading cause of vision loss in the United States, and the leading cause of blindness worldwide. Prevent Blindness has declared June as Cataract Awareness Month to educate the public on risk factors, symptoms, types of cataract, and cataract surgery.
A cataract is a clouding of the eye’s lens which blocks or changes the passage of light into the eye. The lens of the eye is located behind the pupil and the colored iris and is normally transparent. The lens helps to focus images onto the retina – which transmits the images to the brain.”
