Not every vision examination ends in a pair of glasses. If your examination indicates a need, however, your optometrist will prescribe glasses or contact lenses, based on your vision needs and personal choice. If you need vision therapy, he or she can design a program for you or refer you to an optometrist who specializes in this area. It will involve prescribed visual tasks under controlled conditions to correct specific vision problems and to improve your vision skills. Lenses can be used in conjunction with vision therapy. And, in some cases, he or she may prescribe medications or refer you to another practitioner for treatment.
