Types of Vision.

There are multiple types of lenses available for different needs. The information below will describe the various types of lenses available for individual needs and preferences.

 

Single Vision

Single vision lenses have one power from edge to edge. These eyeglass lenses are typically prescribed to correct for nearsightedness, farsightedness, and astigmatism. They're the most common type of prescription lens. 


 

Bifocal 

Bifocal lenses give you close-up lens power on the bottom of the lens (for reading, texting, close detail work) while also providing distance vision on the top of the lens. The fields are divided by a visible line.

 

Trifocal

Trifocal lenses take the bifocal one step further by adding a section for people who need help seeing objects that are within a couple of feet or so. These lenses give you three focal points in one lens to help you see close-up, mid-range (typically for computer or seeing your car dashboard), and far-away. There are also visible lines in trifocal lenses. Your prescription will specify trifocal.

 

Traditional Progressive

Progressive lenses give you two or three focal points in one lens to help you see near and far without switching your glasses. Unlike typical bifocals and trifocals, progressive lenses don’t have lines separating the lens sections. Progressive lenses have a smooth progression of power between distance and near.

 

Digital Progressive (free form)

With digital HD progressive lenses, the fabrication of the lenses from wearer's eyeglass prescription is optimized with computer-controlled surfacing equipment that is much more precise than traditional progressives.  This provides the most accurate lens power and the sharpest vision possible, giving you a wider reading, intermediate and distance area while reducing peripheral distortion.
