This has got to be one of the more famous wives tales out there. However, the relationship between carrots and eyesight correction isn’t completely disparate. Allow me to explain.
The problem with eating carrots to improve your eyesight is that you’d probably have to eat about 1Kg of these things to notice any additional benefit, by which time you’d probably be ill in hospital and wouldn’t be able to realize the benefits anyway! More seriously, the reason carrots were considered as a food that may improve eyesight is actually due to the vitamin A that is held within this vegetable.
Vitamin A is quite an important substance for the eyes because it is responsible for the maintenance of the cornea and a deficiency can cause a few problems with regards to eyesight.
I’ll give you an example. When you’re out at night walking the dog and it’s pitch black your eyes can adjust to the darkness levels and after a while you may be able to see reasonably well. If, however, a car comes round the corner with headlights glaring, then your eyes instantly adjust to the new light levels. Once the car is out of sight there is a period of time (often called lag time) that is required for your eyes to revert back to the state they were in before the car incident. A vitamin A deficiency can increase this lag time substantially.
Of course, you don’t have to just eat carrots, there are other foods that are high in Beta Carotene and vitamin A. Most notably, these are: whole milk, live and eggs. And if you still feel that you aren’t getting enough vitamin A in your diet then you can always consider supplementation.
So, do carrots improve eyesight? Eating carrots could improve your eyesight, but you’re far better off looking into alternative more manageable means!
In fact, if you’re struggling to see properly at night then there are a number of natural exercises that you can do to improve your eye’s effectiveness. The exercises involve strengthening the muscles in the eye which allows it to focus better on objects at times of low light. These eye exercises can even help people who have perfect vision during the day time and only require around 2-4 minutes per day for a few weeks.
