Lens Tint Guide
When you see the percentage numbers next to a lens tint, that describes the amount of light that is being let through the lens. For example, 8-9% is a very dark lens, 35% is a very light sunglass lens and 96% is a clear lens. The chart above shows the percentage range we would recommend for each light condition. In lens guides, Visual Light Transmission is sometimes shortened to VLT.
Lens Materials 101
Prescription trail running sunglasses typically use lenses made of either high grade polycarbonate or Trivex, another composite lens material. Both are lightweight and shatterproof and provide excellent clarity. Trivex is a slightly better material in terms of clarity, but most people have a hard time telling the difference and both result in excellent lenses in terms of optical quality and impact protection.
Polarized vs. Non-Polarized Lenses
Polarized lenses are great on bright sunny days, but they are not a neccessity in lenses used primarily for trail running. The exception to this is if you frequently run in exposed areas, like the desert or Moab, then polarized lenses would be the right choice for you. The polarization filter effectively cuts glare and reduces eye fatigue and it’s hard to perform your best when squinting. Our rule of thumb is that if your face is relaxed then your body tends to feel more relaxed as well.
Progressive vs. Single Vision
If you normally use progressive lenses in your everyday glasses, should you get them in your running eyewear? There isn’t a perfect answer to this one, usually runners will know for sure if they want them or not. If you are on the fence, we would recommend getting progressive lenses if your “add” power (reading magnification) was +2.00 or higher. If your "add" is weaker, for example +1.50, you can likely make out the numbers on your heart rate monitor or watch without the reading magnification. In our opinion, the benefit of not giving up lens space for the magnification portion, seems to outweigh the inconvenience of squinting a little to read your watch.
