Lens Designs
Single Vision
This lens is used either for distance or near vision correction. It is available in all materials.
Bifocals
Bifocals provide both distance and near correction in one lens. They come in two sizes: FT-28 and FT-35.
Trifocals
A trifocal is a bifocal lens plus an intermediate correction portion that allows clear vision for computer distance.
Progressives
Progressive lenses allow uninterrupted vision at all distances – distance, intermediate, and near. The lens gradually transitions from distance to near. It is available in all materials.
