It isn't always clear how they start, but certain eye-related myths seem to crop up again and again. We’re setting the record straight on ten of these common misconceptions.
Myth 1: Soft contact lens expiration dates are only there to generate more money for manufacturers. As long as the packaging is unopen, they are fine to wear.
Truth: Because soft contact lenses are medical devices that must be sterilized and packaged in sealed containers before being sold to eye doctors and consumers, discard soft contact lenses when they expire. Your eyes could become contaminated if you wear them.
Myth 2: You don’t need an eye exam if you don’t notice a change in vision.
Truth: Regular eye exams can detect eye disease, identify other health problems, and correct vision problems at an early stage that could prevent more damage from taking place.
Myth 3: If you cross your eyes too much will they stay that way.
Truth: Crossing your eyes will not cause permanent damage to your vision. Our eyes naturally angle toward each other when viewing something up close. Crossing your eyes on purpose is just exaggerating your eyes’ natural response.
Myth 4: Your eyes are protected when staring at the sun through sunglasses.
Truth: Avoid staring at the sun. The sun’s ultra-violet UV rays can cause damage to your cornea, lens, and retina. Many sunglasses can offer you UV ray protection, but not 100%.
Myth 5: Blue light from your computer or digital device will destroy your eyesight.
Truth: Although prolonged exposure to blue light emitted from digital screens can cause digital eye strain and retina damage, staring at anything for an extended period of time can cause eye strain. When staring at a screen or reading, you tend to blink less. This causes dryness and eye fatigue, but can be easily remedied by taking regular breaks and frequently glancing away from the screen.
Myth 6: There is no way to prevent eyes from deteriorating with age.
Truth: As we age, our vision will naturally deteriorate and lose its sharpness. But, you can slow this process by eating a healthy diet, wearing protective eye gear such as goggles or sunglasses when required, and undergoing regular eye exams.
Myth 7: Wearing someone else’s glasses will ruin your eyesight.
Truth: If you wear someone else’s prescription glasses, your eyes will attempt to adjust to another person’s vision correction measurements and this can cause headaches, eye strain, and even disorientation. For those reasons, it is not recommended.
Myth 8: Your sight can improve by eating carrots.
Truth: Carrots are a source of essential nutrients beta-carotene and vitamin A. While eating carrots will not improve your eyesight, it’s a good idea to include them as part of a healthy diet.
Myth 9: Sitting too close to the TV will make you blind.
Truth: There is no scientific proof that sitting too close to a television screen will cause any damage to your eyesight. However, if you need to sit close to the television to see clearly, you may already have vision problems. Sitting close to any object to see it better is a symptom of nearsightedness and you should make an appointment right away with your eye care professional.
Myth 10: Reading in the dark will ruin your eyes.
Truth: Focusing on something up close without adequate lighting may cause eye strain, but it won’t create lasting damage to your vision. Try a portable reading light to prevent the onset of headaches and blurring of words related to eye strain.
