Prescription Lenses 

Types of Prescription Lenses 

  • Single Vision - Single Vision Lenses are the most common type of prescription lenses.  These lenses have one prescription from edge to edge.  Prescribed for nearsightedness, farsightedness, and astigmatism.  

  • Bifocal and Trifocals - Bifocals and trifocals have two or three prescriptions built into the lens, normally a distance and reading prescription.  A distinct line in the lens separates these prescriptions     

  • Progressive - A Progressive lens provide three prescriptions in one lens distance, intermediate, and reading.  This lens has no lines in between each prescription and gives more natural vision.

  • Computer/Office Lens - This newest type of lens technology, provides intermediate and reading prescription.  This allows clear vision from your computer or phone to your office space surroundings.

Lens Features


  • Standard Plastic (Cr-39).  Standard Plastic lenses are affordable and light weight.

  • Polycarbonate. Polycarbonate are thin, lightweight, shatter proof lenses, and do not have a lot of distortion.  This material is necessary for kids and active adults.  Polycarbonate lens are durable and can take a lot more abuse. 

  • High Index.  High index lenses offer the thinnest, lighter weight material option for strong prescription wearers.  Since high index lenses are slim and sleek they can be fit in a lot of frames no matter what the prescription is.  

Add on Lens Features

  • Scratch Resistant Coating.  Lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel. Kids' lenses, especially, benefit from a scratch-resistant hard coat for greater durability.

  • Anti-reflective Coating.  Eliminates reflections from the front and back surface of eyeglass lenses.  Eyeglass wearers who use their phone a lot and night time drivers should add this coating.

  • UV Coating.  Overexposure to ultraviolet light is thought to be a cause of cataracts, retinal damage and other eye problems.  UV-protective treatments for eyeglass lenses block those same rays from damaging your eyes.

  • Transition Lenses.  Transition lenses get darker when you are out in the sun and change back to clear when you are inside. Its like having sunglasses built into your regular glasses.

  • Blue Blocking Lenses.  Blue blocking lenses block harmful blue light from your eyes.   Overexposure to blue light could cause all kinds of problems, including dry eyes to digital eye strain, sleep cycle disruption, and even macular degeneration.

  • Mirror Coatings and tints.  Change the color of your lenses with mirror coatings and tints.  Make your lenses match your personality.
