After successful cataract surgery on both eyes, I was able to retire and replace the RX lenses I have worn in my Rydon carbon frame sunglasses since I bought them many years ago. I ordered the Color Polar 3FX Grey Laser lenses locally (in Canada). These lenses are polarized, which reduces glare significantly. The quality, fit, and clarity are superb. I strongly recommend them.
The Smoke Black: 22 percent Light Transmission are truly dark and perfect for summer or really bright days. And like the other Rydon spare lenses, they are easy to change out if the light or weather changes.
The transparent (92 percent Light Transmission) spare lenses are a must-have for riding in the fall and winter months when there isn't as much sun.
They're also great on mixed weather days when the sun is out, but the chance of rain is high. The lenses are small enough to carry with you in the included cloth holder and can be swapped out should the need arise. What's more, objects appear super clear through these lenses.
