Single vision occurs when an individual is near sighted or far sighted, but not near sighted and far sighted.

A lens with two points of focus - usually one for distance and one for near vision. Bifocal portion of lens is in the shape of a half moon.

A no-line multi-focal lens that includes all corrections, from distance to close-up, in one lens without any separation of the visual zones by a line.

Anti-reflective coatings eliminate the distracting glare that can be produced by light when it reflects through your lenses. Anyone subjected to direct or indirect reflections – especially those who spend a lot of time around computers and electronic monitors of any type, suffer from eye strain, or who drive at night – will likely enjoy the benefits of glare reduction. Due to the high reflective properties of high index lenses, an anti-reflective coating is recommended, and is practically mandatory for high index lenses made of glass. (Note: AR coating is not good for outside glasses, dusty dirty environments and or constant cleaning.) The lenses must be wet before they are cleaned.

Our Premium Anti-Reflective (AR) plus Super Hydrophobic coating is a premium A/R coating with a Super Hydrophobic topcoat that helps protect the A/R coating from the outside, encapsulating it in a manner that promotes longer Anti-Reflective life. Besides protecting the lens from water, the super hydrophobic coating makes the lens easier to clean.

An anti-fog coating works by chemically affecting the adhesion of water molecules, preventing them grouping into larger clusters that can impair vision. If your glasses are frequently exposed to temperature changes or humid conditions, you’ll likely want an anti-fog coating to help combat condensation. The same goes for anyone who engages in strenuous activities such as physical labor, participation in sports, or exercise. Any activity that causes your body temperature to fluctuate will likely lead to lens fogging.
