Study: Vitamin C may be latest weapon in fight against cataracts

Wed, Mar 30, 2016

Vitamin C’s reputation as a cold and flu fighter may have added another aspect to its healthfulness. The nutrient might also protect against cataracts, a new study says.


The study, published online in Ophthalmology, the journal of the American Academy of Ophthalmology, included more than 1,000 pairs of 60-year-old females. All were British twins. Study participants who consumed a diet high in vitamin C had a one-third lower cataract risk.


Cataracts occur when a clear lens inside the eye turns cloudy. This cloud changes the way light enters the eye, causing blurred images, glare, poor contrast, or starbursts. Cataracts are naturally occurring and can be caused by many conditions, usually the result of age.


Researchers attributed vitamin C’s apparent protection against cataracts to its strength as an antioxidant. The fluid within the eye typically is high in vitamin C. That helps prevent oxidation, which can lead to clouding in the eye lens. A vitamin C-rich diet may boost the amount of the vitamin in the eye fluid, providing extra protection against cataract.


The study’s findings come as welcome news to Dr. Larry Meyer of BayCare Clinic Eye Specialists.


“Any research that advocates healthy eating, balanced diet and the importance of vitamins and nutrients is worth paying attention to,” he said. “Cataracts will affect most Americans by the time they turn 80, so every little bit of useful information in the fight against this condition helps.”


Surgery is the only effective way to treat cataracts once they develop.
