Selecting Prescription Lens Focus
Single Vision or Multi-Focal lens:
If you’re not sure what a multi-focal lens is, you’re probably too young to need one. A multi-focal lens is either a bifocal or a progressive lens with the reading prescription on the bottom.
Single Vision lenses correct distance vision only. There is no magnification for reading in the bottom of the lens.
Bifocals correct for distance vision throughout most of the lens, and there is a segment on the lower portion of the lens for reading or seeing things closer to your face. When we put a bifocal in sports eyewear we make the reading area fairly small. Our goal is to provide just enough reading area to be usable, but not large enough to get in your way. If you want more than a small reading area, let us know before we start on your lenses. Bifocal lenses are NOT digital.
Progressive lenses are available in any Rx-able frame. If you're ordering sunglasses and you don’t wear progressive lenses every day, you may not 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, so you can expect to have a smaller reading area and a smaller mid-distance area in our sports lenses 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 for eyeglasses we will send you a pair of the glasses so you can get a picture of the glasses on your face. This way we know exactly where to put the reading part of the lens.
Free-Form Digital Prescription Lenses:
We highly recommend Free-Form Digital prescription lenses in any frame, especially if the frame is curved. Traditional lenses will cause a “fishbowl effect” when placed on a wrap-style frame. In a Free-Form lens, your prescription is recalculated at every point on the lens. This computer-aided design produces sharp, clear vision throughout the entire lens. This technology completely eliminates the fishbowl effect and provides a much wider field of usable vision. It also makes it much easier to get acclimated to the change in base curve, so you won’t get that wobbly, nauseous feeling sometimes associated with getting acclimated to new, curved prescription lenses.
If you have sunglasses with a Free-Form Digital lens you will find the transition from sunglasses to regular eyeglasses a bit easier if your eyeglasses also have a Free-Form lens.
If you don't see an option for a digital lens, then ALL the choices are digital.
