Bifocal Lenses - Made with a main lens and an additional segment for near vision, the bifocal lenses are available in a variety of shapes of near addition.
Trifocal Lenses - The trifocal lenses are composed of a main lens and two reading segments; one that assists with nearsighted vision, and one for intermediate distances (about arm's length).
Multifocals - Composed of a main lens, our Multifocals have continuously variable additions for all manner of near reading positions.
Aphakic Lenses - These high-power plus lenses are made with aspheric surfaces to minimize aberrations due to the shape of the lens. They are predominantly used for cataract patients.
Photochromic Lenses - The photochromic lenses are designed to darken when exposed to short wavelength radiation (300nm – 400nm) or ultra-violet light. The rate of darkening and final transmission of the lens (saturation transmission) is dependent on the ambient temperature. Your lenses will not darken when driving due to the UV absorption of car windows and windshields.
Coated Lenses - The surface reflection of coated lenses is related to the material index so that different lens materials will have varying amounts of surface reflectance. They are often treated with a surface coating (vacuum coating) to reduce unwanted reflections. Reflections are classified as 4 main types, which include:
