Eye Myths Debunked
There are many truths about vision – and just as many myths. Don’t be April fooled! Here are some common beliefs about vision that simply aren’t true.
Myth: Reading in dim light can damage your eyes
This is something you may have been told by your parents. While it’s true that reading in dim light can cause eye fatigue, it won’t permanently damage your vision.1 Phew!
Myth: Vision screenings are the same as eye exams
Vision screenings test the sharpness of your vision and often come along with physical exams. This is done by having the patient read a chart of letters one eye at a time. Eye exams are much more comprehensive. They test for things like cataracts, glaucoma, diabetic retinopathy and macular degeneration.2
Myth: Eating carrots will improve your vision
Carrots have vitamin A, which is important for healthy eyesight, but eating them won’t improve vision, rather just maintain it. This lore started in World War II, when Britain’s air ministry touted carrots as the reason for their night vision, a lie to throw off the German’s finding out about their new technology.3 Who knew?
Myth: There’s no way to prevent vision loss from happening
Fortunately, there are many ways to take care of your vision such as exercise, having a healthy diet, and wearing protective eye gear when necessary. Vision does naturally deteriorate for many people with age; seeing an eye doctor regularly can help detect any problems early on.
Myth: The eye is full size at birth
Babies’ eyeballs are 16 millimeters wide at birth. That’s why they look so darn cute! By the age of three, they grow to be 23 millimeters wide, and hit the maximum size when you hit puberty – around 24 millimeters wide.4
