From Carrots to Screens — 7 Eye Myths We Still Believe

Most of us grew up hearing these lines from parents and grandparents. Today, social media adds a fresh batch every day. But when it comes to our eyes, good intentions don't always make good advice.

Let's look at seven common myths.

Myth 1: Wearing Glasses Makes Your Eyes Weaker

Glasses don't weaken your eyes, and they don't create dependence. They correct refractive errors such as myopia (short-sightedness), hyperopia (long-sightedness) and astigmatism by helping light focus properly, so the world looks clearer [1].

If a child with myopia takes off their glasses and everything turns blurry, the glasses aren't to blame. The refractive error was always there.

For children, though, one distinction matters. Glasses give clear vision, but they don't necessarily slow myopia down. If myopia is progressing, an eye-care professional may suggest evidence-based myopia-management options [4].

Myth 2: Carrots Give You Perfect Eyesight

Carrots contain beta-carotene, which the body converts into vitamin A, a nutrient essential for normal vision and healthy eye tissue.

But no amount of carrots can cure myopia, hyperopia or astigmatism, or replace a prescription for glasses [2].

Myth 3: Sitting Close to the TV Permanently Damages Your Eyes

Sitting close to a screen doesn't automatically cause lasting damage. Long stretches of near work, however, can bring tired eyes, dryness, headaches and temporary trouble shifting focus.

There's a better reason for parents to pay attention when a child keeps sitting too close or holds books right up to their face.

Myth 4: Eye Exercises Can Replace Glasses

Some exercises do help with specific focusing or binocular-vision problems, when recommended by a trained eye-care professional. But they don't generally eliminate refractive errors like myopia or astigmatism [1].

So when an online video promises that a few minutes a day will banish your spectacles for good, ask one question: What's the evidence?

Myth 5: If a Child Can Read the Blackboard, Their Eyes Are Fine

Seeing clearly at a distance matters, but vision is about much more than reading letters off a chart. Children also need their eyes to focus accurately, work together comfortably and stay attentive during reading and other close-up tasks [2].

Frequent headaches, closing one eye, losing their place while reading, avoiding books, double vision or difficulty with visually demanding activities can all point to a problem, even in a child who seems to see well enough.

Myth 6: Screens Are Destroying Children's Eyes

Screens are now woven into school, homework, entertainment and daily communication. Long periods of close-up concentration without breaks can cause digital eye strain [3].

But blaming screens for every childhood vision problem is an oversimplification. In childhood myopia, family history, near-work demands, time spent outdoors and the child's overall visual environment all play a part [4,5].

Parents don't need to declare war on every screen in the house. Sensible habits, regular breaks, plenty of outdoor time and appropriate eye care go a long way.

Myth 7: If My Child Has Myopia, All We Can Do Is Change the Glasses

Clear, comfortable vision comes first. But childhood myopia can progress as the eye grows, and higher levels of myopia carry a greater lifetime risk of certain eye conditions [5].

So go beyond asking, "What's my child's new prescription?" Try this instead:

What Should Parents Actually Do?

You don't need to be an eye expert. You just need to notice the clues:

• Persistent squinting
• Difficulty seeing the board
• Sitting unusually close to screens
• Holding books very close
• Frequent headaches or eye rubbing
• Avoiding visually demanding activities

Children often don't realise their vision has changed. If blurriness creeps in slowly, they may assume everyone sees the world that way. Regular eye check-ups can catch problems early [2].

🔍 The Facts Behind the Folklore

Carrots are nutritious. Glasses don't weaken eyes. Screens call for sensible habits, not panic. And an eye exercise promoted online isn't automatically a treatment.

So the next time a child edges closer to the screen, resist the urge to say "move back." Ask why.

Sometimes the smallest change in behaviour is the first sign that a child's vision needs attention.

When it comes to eye health, the facts are worth seeing clearly.
