Vision Myths: Fact from Fiction
By Graham R. Stetson, OD, MS
When it comes to vision and eye health, misconceptions abound, and these fallacies can lead to improper treatment and unnecessary worry. Let’s see if we can clear up a few common myths and help you take better care of your eyes.
Myth: Reading in dim light (or sitting too close to the TV/using a computer or smartphone) damages your eyes.
Fact: All these situations can lead to eye strain and dry eye, making your eyes feel tired and uncomfortable, but they do not cause any long-term damage. To reduce eye strain and discomfort, always use proper lighting and follow the 20/20/20+ Rule (For every 20 minutes of near/screen time, take a break for 20 seconds, looking at something 20 feet away, plus squeeze your eyes tightly 5 times). Keep in mind, sitting too close to the TV or holding books/phones too close may be signs of a vision problem and should be evaluated.
Myth: Carrots are the best food for your eyes.
Fact: While carrots, rich in vitamin A, are beneficial, they are not the only food that can promote eye health. Leafy greens like spinach and kale, omega-3 fish oils, nuts, winter squash, and citrus fruits also contribute to maintaining good vision.
Myth: Wearing glasses will weaken your eyes.
Fact: Glasses help correct visual errors. They do not make your eyes weaker or dependent on glasses. Instead, they ensure that you can see correctly and reduce eye strain.
Myth: Eye exams are only necessary if you have vision problems.
Fact:Regular eye exams are essential even if you do not have apparent vision problems. They can detect eye conditions that may not have noticeable early symptoms, like glaucoma and macular degeneration, as well as other health issues like diabetes and high blood pressure.
Myth: Wearing someone else's glasses will damage your eyes.
Fact: Wearing someone else's prescription glasses will not harm your eyes, but can cause discomfort, headaches, and blurred vision since they are not tailored to your visual needs.
Myth: You only need sunglasses on sunny days.
Fact: UV rays can damage your eyes even on cloudy days. Wearing sunglasses with 100% UV protection whenever you're outside can help delay cataracts and other UV-related eye damage.
Understanding the facts about eye health can help you take better care of your vision. Regular check-ups, a balanced diet, and protective measures are key to maintaining healthy eyes.
