Unsubstantiated Warnings
Myths are responses to subjects of concern that have been repeated through generations until it is assumed they are true. Common myths about reading glasses and eyeglasses in general include:
These warnings have no more truth than old wives' tales like: reading in the dark damages eyes, overuse of eyes makes vision worse, and eating carrots improves vision.
Only the Facts Using one's eyes for extended periods of time or reading in the dark does not make eyes weaker; it simply puts a strain on eyes and could cause headaches - correctable with rest. Reading glasses are not necessary due to weak eye muscles; maturity causes the lens of the eye to stiffen, making it difficult for the muscles to do their job. There is no research to indicate that eye exercises improve vision or repair damage caused by eye diseases or conditions that are a result of aging. Over-the-counter reading glasses cannot damage eyes. However, they are not ophthalmic quality eyewear, and distortions in lenses can cause eyestrain. Wearing someone else's glasses or the wrong glasses will cause temporary eyestrain - nothing more. As for the myth about eating carrots to improve vision, vitamins found in carrots help to maintain normally healthy eyes, and a vitamin deficiency can lead to blindness. | ![]() |
