as old as the doctor will let you
at least 7 years of age
I am 13 and i use the contact lenses.But its safer to start at 14,because it might sometimes irritate you.
There is no age limit, just as soon as you are responsible enough to keep them clean. ^_^
No way! I think being older is just a 'figure of speech'. You have to try as hard as you can to keep your youth up, and not wearing glasses might shave of 10-15 yrs.
when you want to start wearing them
There is no minimum age requirement for wearing a contact lens. One limitation would be the care and dexterity needed to put the contacts in and take them out, and clean them. Many eye doctors would encourage a contact lens for someone 11 years or older, as long as they are able to use the chemical cleaners safely and are responsible.
The same age you can start playing hockey.
About ten years old.
As people age, the lens hardens and changes shape less easily.
When a girl should wear a bra is not based on a certain age. She should wear a bra when her breasts start showing.
any one can were them theres no age limit. even babys can were them
Schools normally start contact sports like rugby at the age of 11
