Bifocal lenses are eyeglasses with two distinct optical powers. Originally, bifocal lenses were designed with most convex lenses in the lower half and the least convex lenses on the upper of the frame. With new technology and development in the material researches have manufactured such a lens using a liquid crystal layer sandwiched among two glass substrates for reducing problem of headaches while using bifocal lens.
