Sometimes those bits of wisdom that “everybody knows” just have to be true. In this case, yes, carrots really are good for your eyes.
A report at the recent American Academy of Ophthalmology (AAO) – Middle East-Africa Council of Ophthalmology (MEACO) Joint Meeting described how beta carotene can help people with retinitis pigmentosa.
Retinitis pigmentosa is a hereditary disease most often marked by the onset of nightblindness during childhood that eventually leads to a loss of peripheral and eventually in many cases blindness. Previous research has shown beta carotene, 9-cis, can help treat night blindness. In this study, one third of the retinitis pigmentosa patients under observation showed improved visual function after taking a beta carotene supplement for 90 days.
