Q: If I want contact lenses can I use my glasses prescription to get them?
A: No, a contact lens fitting is necessary. Because a contact lens is a medical device that contacts your cornea and the underside of your eyelids it must be fit to your eye to avoid the complications of a poor fit. The necessary power of your lens can be different with contacts as well. One reason for this is that the contact lens sits on the front surface of the eye, whereas the lens in a pair of glasses is about 1.5 cm in front of the eye. Insertion and removal training is also necessary for first-time contact lens wearers.
