To be honest I have no idea, I have clear lens version and I never used lens with coated lenses. My buddy bought an Aqualung mask with coating and never used twice. So I can recommend you to try a before buy.Is the UV version worth the extra cost? Does it make the view dimmer underwater or does it just cut glare? If I dive at some deeper depths, the last thing I want is significantly less light. ON the other hand, if the reduction in light is very small with the coating, and it cuts scattering glare from debris, it may actually make the visibility appear clearer.
