Sunglasses Lens Information

Selecting a Lens Material

There are only two lens materials approved for use as sports lenses: polycarbonate and Trivex. If you are purchasing glasses for an activity that could lead to facial impact, you need unbreakable lenses.


Selecting a Lens Color

The right lens color can improve contrast, ease eyestrain, and generally improve your vision. As you select a lens color, you should also decide on whether you want a polarized lens or not. The newest polarization technologies have the greatest impact on glare, regardless of color.


Selecting Lens Treatments and Coatings

Lenses can be polarized, photochromic (Transitions - changing from light to dark) or tinted to reduce glare and eyestrain. Anti-reflective or Flash (Mirror) coatings can be added to lenses to help with scratch resistance and glare as well.


Free-Form Digital Lens Surfacing

Free-Form Digital lenses are the most important improvement in sports eyewear. We highly recommend free-form lenses in any frame, any prescription, every time. If you are getting a wrap style sports frame, this free-form digital design is even more important.


Prescription Lens Information (Rx)

Even more information on prescription lenses! We believe being a well-informed consumer will enable you to get the best value for your dollar when purchasing prescription sunglasses. You can't really understand prescription lenses without some knowledge of diopters and base curve. Learn more about diopters, base curve and high minus prescriptions.


Understanding the Prescription Order Form

When ordering prescription sunglasses, we ask for your prescription information in a form on the order page. We do this so that we can make sure the pair of sunglasses you have selected will work with your prescription, and then of course, to actually make the lenses. The article explains the meanings of all the numbers in your prescription.
