II. Round Top Bifocals:
You focus through different prescriptions at different distances through the same lens - hence the name. Bifocals (meaning a lens with two points of focus - usually one for distance and one for near) are the most commonly prescribed multifocal lenses.
Bifocal the upper part of the lens is generally used for distance vision, while the lower part is used for near vision. Usually, a segment line separates the two.
Typically a person with myopia would have one section of a prescription lens that has a certain diverging power while another section of the lens would havea lower diverging power for close-up work. Similarly a person with hyperopia would have one section of the lens with a certain converging power and another section with a greater power for close-up work.
Bifocal sare typically placed so the line rests at the same height as the wearer's lower eyelid. As a bifocal wearer drops his eyes downward to read, the eyes naturally seek out the near-vision portion of the lens.
In an effort to decrease the chromatic changes and the object jump which are problems with fused bifocals, flat-top solid bifocals have been made. They have the advantage of lowered chromatic change and of no jump or no shift in the objects when the gaze is shifted from distance to near.
