Cataracts are the most common cause of vision loss in people over age 40, and are the principal cause of blindness in the world. According to Prevent Blindness America, there are more cases of cataracts worldwide than there are of glaucoma, macular degeneration, and diabetic retinopathy combined.
A cataract is a clouding of the lens in the eye that affects vision, and are related to aging and common in older people. By age 80, more than half of all Americans have either a cataract or have had cataract surgery.
Symptoms of Cataracts:
• Blurred or hazy vision
• Reduced intensity of colors
• Increased sensitivity to glare from lights
• Increased difficulty seeing at night
• Change in the eye’s refractive error
Cataract Risk Factors:
• UV Rays
• Previous eye injury
• Hormone replacement therapy
• Family history
While it is inconclusive whether cataracts can truly be prevented, there have been numerous studies suggesting diets high in certain nutrients and nutritional supplements may help reduce the risk.
These nutrients include:
• Vitamin E (such as sunflower seeds, almonds and spinach)
• Lutein & Zeaxanthin (such as spinach, kale and other leafy greens)
• Antioxidants (vitamin C and omega-3 fatty acids)
