The bifocal lens which is made to any shape or size, allows for different amounts of prism, to be prescribed in both the distance and near vision portions of the lens.

Double Vision (Diplopia)

Double vision (medically known as diplopia) is seeing two images of a single object. The two images may be one on top of the other, side by side, or even a mix of both.
