5 TRUTH about protecting your eyes
Of your five senses, which one are you most afraid of losing? If you’re like most people, your answer is your ability to see. Because our eyesight is so precious, it’s no wonder that myths abound about what can damage our eyes — and what can protect them. Here, we debunk five common myths — and tell you how to truly keep your eyes healthy.
Myth: Doing eye exercises will delay the need for glasses.

Your vision depends on many factors, including the shape of your eyeball and the health of the eye tissues, neither of which can be significantly altered with eye exercises. Myth: Reading in dim light will worsen your vision. Fact: Dim lighting will not damage your eyesight. However, it will tire your eyes out more quickly. The best way to position a reading light is to have it shine directly onto the page, not over your shoulder. A desk lamp with an opaque shade pointing directly at the reading material is ideal.Myth: Carrots are the best food for the eyes. Fact: Carrots, which contain vitamin A, are indeed good for the eyes. But fresh fruits and dark green leafy vegetables, which contain more antioxidant vitamins such as C and E, are even better. Antioxidants may even help protect the eyes against cataracts and age-related macular degeneration. Just don’t expect them to prevent or correct basic vision problems such as near-sightedness or far-sightedness.Myth: It’s best not to wear glasses or contact
