Color Contacts?, parents won't allow it Options

[iExquisite]

Hey guys,
well i am 15 && i am in a bit of a situation
i currently wear glasses and i extremely want colored contacts
but the thing is my mother won't allow it
she said contacts are for people who can't really see well or can't see at all
if something is far away i can't see it especially in class, if i sit in the back
i won't see anything on the board, it it will be all blurry- so i usually put on my glasses

but i really want colored contacts- to enhance my look
my eye color is black

any ideas how i can convince my mother?
any replies will be very appreciated!
