    1) Our bifocals are made from the highest quality materials, in Uncoated, Hard-Coated and Hard-Multi-Coated varieties. We understand that people have different needs in bifocals, so we have created a wide range of these products. It also means we can fulfill all types of orders in bifocals. We encourage you to contact us with questions or for clarifications and price lists. We will be happy to assist in any way we can.

    2) With a segment in the lower area of the lens, a bifocal lens displays two different dioptric powers, which provides presbyopes with clear vision for both near and distance visions.

    3) Bifocal lens can be called a multi purpose lens. It has 2 different fields of vision in one visible lens. The larger of the lens usually has the prescription necessary for you to see for distance. However, this can also be your prescription for computer use or intermediate range, as you would normally be looking straight when you view through this particular part of the lens. The lower part, also called the window, typically has your reading prescription. Since you generally look down to read, this is the logical place to put this range of vision assistance.
