As people age, cataracts are a common side effect. It is considered the number one source of blindness throughout the world. Cataract is a medical condition where the eye lens becomes opaque, resulting in reduced eye site. A recent study done by Ophthalmology researched the effect of genetics versus the environment upon obtaining cataracts. In this study, there were one thousand pairs of female twins that had their intake of vitamins A, B, C, D, and E and then copper, manganese, and zinc along with other nutrients recorded. They then assessed each for the progression of cataracts. A surprising result unfolded: “Genetic factors were responsible for 35% of the difference in cataract progression, while environmental factors, such as diet, accounted for 65%...” (Brazier 2016) This study revealed that genetics actually plays less substantial impact than environmental. As they assessed the environmental impact, researchers realized the overwhelming impact of Vitamin C. “The 10-year assessment revealed a 33% lower risk of cataract progression in women whose diet was rich in foods containing vitamin C.” (Brazier 2016) It is believed that due to vitamin C’s antioxidant properties the oxidation process that causes cataracts is stopped. Finding this link between Vitamin C consumption may be the major big step in reducing cataracts.
