Just OK.
Eh. I bought the gray polarized lenses without a prescription. Compared to my Zenni lenses (gray, polarized, CR39), there's no perceptible difference in vision quality. Trees and water do seem to pop a tiny bit more, but that's because the lenses have a slight greenish blue tint and are not a true gray. As a result, color accuracy is compromised and I'm unhappy about that (I wanted gray for a reason). For reference, I've professionally calibrated TVs and computer monitors, and have a perfect score on a color hue test. Customer service offered me to send the lenses back for them to reexamine, but I declined as I didn't think it'd be worth the hassle. Overall, the lenses do not outperform a budget brand, but they're decent. I'd say the gray lenses are in-between an actual gray lens and a green lens. If they prove more resistant to crazing (reason I'm looking to move on from Zenni) then I may keep ordering from this company.
