5 Most Common Vision Myths
Many myths abound when it comes to your vision and what affects it. Thankfully, you don’t need to call the Mythbusters to crack these five famous eye myths because we have the truth here!
Fact: Carrots are rich in vitamin A, which is a necessary vitamin for functioning vision. However, only a very small amount of vitamin A is needed, and the average person already gets more than enough vitamin A in their diet without adding extra carrots. Other foods rich in vitamin A include kale, sweet potato, liver, butternut squash, and cantaloupe.
Eye Myth #2: Your vision will bedamaged if you read in dim light.
Fact: Dim light causes your eyes to work harder to be able to distinguish the letters on the page; however, this does not cause physical damage to your eyes. Instead, your eye muscles will eventually grow tired and you will begin to experience symptoms of “eye strain”: headaches, blurred vision, itching eyes, neck and backaches. But these are temporary and will not permanently damage your vision; any symptoms that last signal an underlying issue.
Eye Myth #3: Children (and adults) do not need an eye exam unless there is something wrong with their vision.
Fact: Children should have yearly comprehensive eye exams to catch any vision issues early BEFORE they cause enough symptoms for a parent or caretaker to notice. School screenings are helpful, but they will not catch many basic vision problems that could be caught in an eye care clinic. Adults should also have regularly scheduled eye exams as a preventative measure to catch any hidden problems.
Eye Myth #4: If you cross your eyes too much, they will get stuck that way.
Fact: Your eye muscles work like other muscles in your body. Crossing your eyes too much will tire them out and cause eye strain, but they will not get stuck, just like holding another muscle in one position will not cause it to be stuck. However, if a child has continuous crossed eyes, he or she should be seen by an optometrist; crossed eyes is not a problem that will be grown out of.
Eye Myth #5: Sitting close to a TV or computer screen, or watching one for too long, causes damage to your vision.
Fact: Much like reading in dim light, you can get eyestrain from being close to a screen, but this causes no lasting damage. No damage is caused by the length of time you spend in front of a screen, either. However, people usually blink less when they are staring at a screen, and this can cause your eyes to dry out and create some of the same symptoms as eye strain. To prevent this, blink often, and allow your eyes to focus on something across the room occasionally if you are close to a screen. Eyedrops can also be used if your eyes are getting too dry.
