The notion that eating carrots improves eyesight sounds like a story your mother made up to get you to eat your vegetables. But is there any truth to it? According to Duke ophthalmologist Jill Koury, MD, there is a connection between eating carrots and maintaining good eyesight.
But there’s nothing magical about the carrots alone -- it’s the vitamin A within the carrots that is so important for eye health. “Vitamin A in normal, recommended quantities is essential for the maintenance of good vision,” explains Koury.
If a person is deprived of vitamin A for too long, the outer segments of the eye’s photoreceptors begin to deteriorate, and the normal chemical processes involved in vision no longer occur. Restoring your vitamin A intake will help restore your vision as well.
Before you run to the store to stock up on bags of carrots, keep in mind that overdosing on carrots in an attempt to improve vision is unlikely to aid in your quest for better vision. In fact, eating too many carrots can cause your skin to appear yellow or yellow-orange due to a build-up of blood carotene levels.
Koury notes that there are no exercises, drops, or special dietary supplements to improve eyesight or protect against the development of sight-threatening conditions.
