Superstitions and myths are something that exist in all realms of life. And that also includes your eyes and eye health. Your eyes are among the most complex and vital organs in your body, yet eye health is often surrounded by misinformation that most people accept without question. We speak with Dr Mandeep Singh Basu, who is an ophthalmologist, on the five most persistent myths ones that he frequently comes across and has to debunk.
Too Much Screen Time Causes Permanent Blindness Staring at screens for long hours can be uncomfortable, but it does not destroy your vision permanently. What it can cause is digital eye strain, including dryness, blurred vision, and headaches. The 20-20-20 rule can help: every 20 minutes, look at something 20 feet
away for 20 seconds. The discomfort may feel intense, but it is usually temporary.
Blue Light Glasses Are a Complete Solution
Blue-light glasses have become increasingly popular, but the scientific evidence supporting them is more limited than marketing claims suggest. The majority of eye strain experienced when viewing screens (via computer/phone/tablet) is caused by decreased blink frequency and poor posture versus being caused by blue light wavelengths. These glasses may offer minor comfort for some people, but they are not a substitute for regular breaks, proper lighting, and good screen habits.
Eating Carrots Will Perfect Your Vision
Beta-carotene is an antioxidant that has many health-promoting qualities. When consumed in sufficient amounts, your body can convert it into vitamin A, which is essential for healthy vision and the maintenance of healthy eyesight. If you already have an adequate amount of vitamin A in your system, additional consumption of carrots will not improve the quality of your vision beyond what is currently present. A balanced diet supports healthy eyesight, but eating only carrots will not improve your vision.
Eye Drops Can Cure All Eye Problems
Over-the-counter drops may relieve dryness and redness but will not address any eye health problems. A doctor must examine you to determine how to treat any eye condition such as cataracts, glaucoma, macular degeneration, and diabetic retinopathy. If you continually use drops to mask the symptoms of eye diseases, you may not realize that your condition is actually worsening. Vision loss happens instantaneously without any prior warning. Most serious vision-threatening diseases develop slowly over time and without any prior notice.
Vision Loss Happens Suddenly Without Warning
Many serious eye conditions worsen gradually over years. Glaucoma is often called “the silent thief of sight” because it gradually damages peripheral vision without creating pain or other visible signs until a lot of damage has been done. Diabetic retinopathy works in a similar way. Routine eye exams are there to find these problems before they go too bad.
The main thing that all of these myths have in common is that they either make harm seem worse than it is or downplay real risk. The best thing you can do for your long-term eye health is to get frequent, full eye exams. Usually, vision loss can be stopped, but only if it is identified early.
