What is recommended if I am extremely farsighted?
If you are farsighted, you will have a problem seeing close up. If you are extremely far- sighted, your lenses will be thick in the centers and will magnify your eyes. To counteract these problems, aspheric lenses (lenses with a computer generated front curvature, which reduces magnification and thickness) were designed. When choosing a frame, avoid rimless ones because they will have very thin edges and will be too fragile to hold the lenses properly.
