Sir,
My daughter is myopic(-1&-7.5). Should she wear glasses throughout the day or only while watching TV? When can she start wearing contacts(she is going to be 19 soon)?

littlebit

she should wear her glasses right through the day or get lenses, because lenses, you dont have to take off any thing, unlike glasses

I would recommend to try natural therapy at your nearest center as it has no side effects and is 100% risk free.

my daughter is 12 years old she suffer from miopia diseases. Now the glases number are -7.5
my daughter cound not stay a day without of cocolat and eat very much salt before. is good for her to eat cocolat every day and do you think can be a didases that cause the miopia to my daughter. thank you

This is not due to any intake problem. Firstly is there a family history of poor vision? Secondly at that age the best prescribed opinion for you would be natural therapy.
