Reducing Oxidative Stress in the Lens Protects Against Cataracts
Cataracts are a condition that makes the lens of the eye cloudy, causing blurred vision, much like looking through a foggy window or a smudged camera lens. This occurs due to protein buildup in the eye's lens. Without treatment, cataracts gradually worsen, leading to more vision loss and, eventually, blindness. (1) Cataracts usually develop with age, and they're very common among older adults. Statistics show that more than half of Americans aged 80 or older either have a cataract or have undergone cataract surgery. Besides aging, other risk factors include heavy alcohol use, smoking, diabetes, exposure to harmful substances, certain medications and eye injuries. (2) Currently, about 24.4 million Americans over age 40 are affected by cataracts, and this number is expected to double to about 50 million by 2050 (3). In response to this growing challenge, researchers at the University of Auckland, New Zealand, explored new strategies for cataract treatment by minimizing oxidativ...
