When I first went to my doctor requesting contact lenses he said that since I suffered from both near and far deficiencies that it would be impossible.  I kept after him each time we would have an appointment and he finally told me of a plan where I could wear one contact on one eye and one contact on the other.  I tried that for several months and experienced head aches the entire time.  Now he as switched me to Proclear Multifocal Contact Lenses.  They have enabled me to see as well as I could with my graduated lenses and their are no head aches.
