Common Eye Myths Debunked

When it comes to eyesight, it important to separate fact from fiction. Knowing how to take good care of your eyes is the first step in protecting your sight. Don’t be blind to the facts – here are some common myths about vision, followed by the facts.

Myth: Watching television for too long or sitting too close can damage your eyes.

Fact: There is no evidence to suggest that this is true. Young children often sit close to the television because they have a greater ability to focus on objects closer to their eyes than adults do. Due to this, children often hold their reading material close as well. However, as they grow older, these habits usually change. If not, this may be a sign of myopia (nearsightedness). To detect possible eye problems, children should have regular eye exams.

Myth: Reading in dim light can damage your eyes.

Fact: Reading in dim light can cause eyestrain, but it will not hurt your eyes permanently.

Myth: Wearing contacts prevents nearsightedness from getting worse.

Fact: Wearing contacts will not permanently correct nearsightedness. Myopia or nearsightedness is usually an inherited condition, and contact lenses can only be expected to improve vision. Contact lenses cannot prevent nearsightedness from getting worse.

Myth: Failure to use proper glasses will hurt your eyes.

Fact: This is true for a small number of people. Some children have eye problems that can be corrected, and it is important that they wear their glasses. But vision problems caused by heredity or physical injury don’t go away, even with glasses. While corrective glasses or contacts are needed to improve eyesight, using your eyes with or without glasses will not damage your vision further.

Myth: Eating carrots will improve your vision.

Fact: While it is true that carrots, as well as many other vegetables are rich in vitamin A, which is essential for sight, only a small amount is necessary for good vision. A well-balanced diet, with or without carrots, provides all the nutrients the body needs. In fact, too much vitamin A, D or E may actually be harmful.

Myth: An eye exam is necessary only if you’re having problems.

Fact: Everyone should follow proper eye healthcare, which includes regular eye exams, whether or not you are having any noticeable signs of problems. Children should be tested at birth, at 6 months of age, before entering school and periodically throughout the school years. For adults, the frequency depends on your doctor’s advice and may be every two years or more often. If you have diabetes or an eye disease, you should go every year for a comprehensive eye exam.

Myth: There’s nothing you can do to prevent vision loss.

Fact: More than 90% of eye injuries can be prevented, when simple and relatively inexpensive safety precautions are followed. That means choosing the correct eye safety glasses for the job and wearing them 100% of the time. Regular eye exams can help save your sight. Early detection of vision problems is crucial to preventing vision loss from many eye diseases – especially diabetic retinopathy and glaucoma.

Myth: Reading fine print for too long will wear out your eyes.

Fact: This is one of the most widely held myths about vision. Some people are concerned that they should not read too much because it will cause damage. Although extensive or prolonged reading of fine print can cause eyestrain, there is no evidence to suggest that it will damage or wear out your eyes.
