Why did my eyesight become bad unexpectedly?

[Malverne]

I have perfect vision before 12,but it changed suddenly . Right now im a 13 year old and have really bad eyesight.someone says my eyesight got worse because i'm still growing and it will get better as my body becomes fully grown. Is that true?

The power of your prescription is irrelevant to your age growth. Glaucoma, Eye strain,incorrect use of eye, heredity & health problems may all be the causes of worse eyesight. You'd better check at your eye doctor to see the exact cause of it in order to cure it.

Does your family have the gene of bad sight? If it does, then you may get bad eyesight suddenly. Or you overuse your eyes during the recent period and then you get bad eyesight suddenly because it is common to get bad sight suddenly during a short time. If you have got bad sight, you'd better go to see your doctor as soon as possible.

No,it is not true.The eyesight has nothing to do with your age,no matter you are still growing or not.If you don't pay much care to your eyes and overuse them constantly,they can get worse faster.

Some eye diseases can cause eyesight to get worse unexpectedly.If you feel much worried about it,you'd better have an eye exam.
