Have you wondered why children tend to watch TV close to the screen?
Eye specialists say kids can actually focus up close without eyestrain better than adults, so they often develop the habit of sitting right in front of the television or holding reading material close to their eyes.
That’s how their eyes work. Children can focus at close distance without eyestrain better than adults because their eye lenses are more flexible and adaptable to close-up viewing. The eyes actually change shape for long distance or close up viewing. And children’s eyes are the most flexible. The eyes start to lose their flexibility as they grow up so as kids get older they will move back from the screen. And this also explains why after 40 most people start to have vision problems – just when all their muscles are aging and seriously losing the flexibility of youth.
Children often develop the habit of holding reading materials close to their eyes or sitting right in front of the television. And to note, there is no evidence that this damages the eyes either in children or adults.
When you are born, the lenses inside your eyes are generally crystal clear and flexible, and the zonules connected to them are strong. With age, the lenses become less flexible, and the zonules are not as effective. Your eye shape, which is genetically determined, may mean that you need corrective lenses. If your eyeballs are too long, you’re nearsighted. If they are somewhat short, you’re farsighted. Whenever you notice a change in your vision, schedule an appointment with an ophthalmologist or an optometrist.
With children, this habit usually diminishes as they grow older.
There is no scientific proof that sitting to close to a TV will cause any damage to your eye site.
However, if you need to sit close to the TV to clearly see what is going on you may already have vision problems. Sitting close to any object to see it better is a symptom of nearsightedness and you should talk with your doctor.
