How long do you have to wear glasses to wear contacts ?
There is no time limit, its all down to your preference. The point is to aid you in your vision improvement. It would however be very important that you contact a Optometrist for an expert analysis.
You could get them the same day.
I got contacts right away but I got glasses too just in case
You don't have to have glasses at all to get contact If you want to. Hope this helped!-Moe
