When you renew your prescription for contact lenses, you should not skip the Doctor's office. Special instruments look into the back of your eye (your retina) to screen for disease. Also, during the visit, your eye pressure is measured for any signs of Glaucoma, a silent disease that could lead to blindness. Be Smart, and don't let yourself be lured into substandard care, as it may cost you more in the long run—your sight!
