Eating carrots will help and sitting too close to the TV will hurt your vision are a few statements all of us have probably heard while growing up. While it is important to keep an eye on your eye health and vision, there are some common myths that have stuck through the years that might not necessarily be true. Always consult with your eye doctor on any issues you may have, but here are some of the common eye myths that keep circulating around, some even are based upon a bit of truth.
Squinting does not make your vision worse- perhaps you have heard your grandma or someone tell you to stop squinting because it will hurt your vision. Squinting may be a sure way to tell if someone may need glasses. By squinting, you are attempting to focus more by making the pupil smaller (closing your lids). If you suffer from a refractive error (near-/farsightedness), your lens cannot bend the light properly to focus the image for you. So you squint, which reduces the light allowed in, and allowTs you to see a little bit better. The only side effect you may experience would be headaches from the muscles on your face to close your lids a bit.
Reading in the dark does not harm your vision- there is a great chance that you were yelled at as a kid to turn a light on while you were reading because “bad lighting is bad for your eyes.” During low light conditions, your pupil will enlarge to allow more light in an attempt to help you to see. This does not damage your eye; you just will not be able to see as well. You can think about your eye as a camera. A camera won’t be damaged just because you take a picture in low light; you just won’t be able to see as well.
Sitting too close to the TV or staring a computer screen only affects vision temporarily- the majority of the time, people who sit too close or stare at screens, do not blink enough to keep the eye sufficiently lubricated, which affects the vision. While only temporarily, people may think there is a serious problem if their vision becomes blurry or eyes become strained. However, we may not have been designed to stare at screens all day, but no permanent damage will come from it. Just make sure to blink as you would normally.
If your parents have poor vision, you may not- while many eye problems and conditions may be genetic, it does not mean that you will automatically inherit them. You may be at a higher risk, but inheritance is no guarantee. The important thing is to remember to get a comprehensive eye exam regularly to catch any problems early on, especially if your family has a history. For example, glaucoma is inheritable, cataracts is an age-related degeneration of the lens that happens to everyone.
Carrots- everyone has probably heard that you should eat carrots to give you better vision. While this is not exactly true, there is a little bit of truth behind it. Carrots are high in vitamin A and a deficiency in vitamin A can lead to poor vision. So by eating an excess of carrots or other foods high in vitamin A, you will not enhance your vision further, but will prevent any deficiencies.
Glasses or contacts do not create a dependence- perhaps you use glasses only during certain situations because you fear that overusing them will cause your eyes to become dependent upon them even more. This is not true and you should use your corrective lenses whenever you feel the need. Wearing corrective lenses does not change the natural physiology of your eye (making your vision worse), however as you age, your vision may begin to deteriorate but that is not from wearing corrective lenses.
You should always consult your eye doctor regarding any questions or concerns you have about your vision or eye health. If your vision has been an area of issue for you or you hate the confining aspect of glasses, have you considered laser eye surgery to permanently correct your vision?
