Selecting a Type of Lens For Your Vision
All of the lenses in this section are Free-Form DigitallySurfaced lenses. This is a big deal. If you’re not aware of the differences please follow the link ablove.
SINGLE VISION
Single Vision lenses correct distance vision only. There is no magnification for reading in the bottom of the lens. If you never wear reading glasses, choose a Single Vision lens here.
PROGRESSIVE
Progressive lenses have a reading portion in the lower area of the lens that gets progressively stonger toward the bottom of the lens. Progressive lens are available in any Rx-able frame.
If you’re ordering sunglasses and you don’t wear progressive lenses every day, you may want to get acclimated to your first pair while participating in a sport or riding a motorcycle. We typically use Short Corridor progressive lenses in sports eyewear. You can expect the reading area in our sports sunglasses to be a bit lower than you have in your everyday progressive lenses. Once again, we are assuming that distance vision is a bigger priority than near vision. Let us know if you are ordering glasses for fishing, or if you want a larger reading area. If you’re ordering a progressive lens we will send you a pair of the glasses so you can get a picture of the glasses on your face. We will use Photoshop and the known height of the lens to calculate where to place the reading corridor in the lens.
�Selecting a Lens Material:
There are only two lens materials approved for use in sports sunglasses: Polycarbonate and Trivex.
Polycarbonate is the most popular lens for sports glasses. It is unbreakable, and is available as a Tinted, Transitions, Clear, or Polarized lens.
Trivex was developed by the U.S. Military as an improvement over polycarbonate. Trivex has a higher Abbe Value than polycarbonate, so there is less Chromatic Abrasion in a Trivex lens. (less peripheral color distortion) Trivex is also available as a Tinted, Transitions, Clear, or Polarized.
CR-39 lenses are made from a plastic that is used frequently in everyday eyewear. This material is breakable, so it may not be a good choice in eyewear intended for active-sport use. We can use CR-39 lenses in prescription inserts that are mounted behind a polycarbonate lens or in a goggle, or in glasses used for driving, fashion, hanging out at the pool, etc.
Polarized Lenses reduce glare and images appear sharper and clearer, increasing visual clarity and comfort.
Photochromic Lenses start out clear indoors, in the shade or inside a car, but turn dark in the bright sunlight.
When you check the “Yes” box for “Send a Try-Out Pair First” the price of the prescription lens you selected will be deducted from your total. We will send you a non-prescription version of this frame to try on, and you will receive a 100% refund on the frame as soon as it is returned. Your only expense to try on these frames is the cost of return shipping. (We pay for the outbound shipping, but not the return shipping.)
You can order as many tryout frames as you like, you're under no obligation to order prescription lenses, and there is never a restocking fee. We want you to be absolutely certain you are enthusiastic about wearing these frames before we make your prescription lenses.
If you like the glasses, email us at [email protected] or call (800) 381-9083 toll-free and confirm that you want the prescription version. Then return the Try-Out pair of glasses in the same box that we used to ship them to you. Include all the original documentation and accessories that were with the glasses when you received them. If you do NOT return the glasses, or if they are not in re-sellable condition, you will not receive your refund. For this reason, we recommend insuring these glasses in transit.
