The answer is definitly NO. Eyeglasses are usually placed at about 12 millimeters away from the eye while the contact lenses are placed directly on the tear film of the eye, the prescription on the contact lenses should be less nearsighted than that of eyeglasses. You can go to your eye doctor to have your eyes checked to see the exact difference.
No. the presvription of the contact lens is different from that of eyeglasses. Usually the prescription of eyeglasses is stronger than that of contact lens.So you'd better not use your contact lens prescription to buy your eyeglasses, which won't work well.
