Hi, I got my new pair of eyeglasses, but my left eye see double images slightly off each other. for example, look at 2 neon horizontal line lights (one about 1 inch above the other) especially in green color, from a distance about 15feet, my left eye through eyeglasses will see "3" lines of neon lights, the "ghost image" is higher than the 2 real image, if I raise my head backward such that I see the neon lights through lower part of my eyeglasses, the "ghost image" will disappear and I see clearly. if I walk closer to about a few feet, double image will disappear, this is left eye only, same with and without my right eye open. I wonder is this due to the not so good prescription of the eyeglasses? what could cause such problem from eyeglasses optically? or is it my left eye that's the cause? (I can't tell since if I look at things with naked left eye everything so burry hard to tell if there's a slightly offset ghost image) another pair of glasses with similar prescription except axis 8 degrees different has the same problem. thanks a lot!
