I am 62 yrs old, My eyes struggle to track. Up close my eyes don t want to move in and at distance they don t want to move out, basically they are stiff and don t want to move. I have 1 pair of glasses for reading and computer that have the correct prism, but need a different prism for distance. I have tried to have 2 pair of glasses but am unable to go back and forth with the different prisms, it makes me dizzy, My doctor has done many things with different prisms, glasses, ect. I have been fighting this for 3 or 4 yrs
