Question:

Does eating carrots really improve your vision?

Answer:

Yes and No. Eating copious quantities of carrots will not prevent or reverse your need for eyeglasses. Carrots however are high in beta-carotene, which gets converted to Vitamin-A in the liver and is an important nutrient with regards to proper eye health. Vitamin-A is an antioxidant and has been shown to slow the formation and progression of degenerative eye diseases like macular degeneration and cataracts. Vitamin-A deficiency can lead to night blindness a condition known as nyctalopia.

Carrots also contain the antioxidant lutein. Lutein is highly concentrated in the central macula area of the eye and helps to protect the eye from age-related macular degeneration, which is currently the leading cause of blindness in patients over the age of 50.

Like all good things, there is a limit. Excessive beta-carotene intake can cause a persons skin to turn orange, and chronic ingestion has been linked with an increase risk of lung cancer in smokers and recent ex-smokers.

Note: Always consult with your health care provider prior to starting any new supplements.
