Atomic SubFrame with Rx is awesome. It's the best mask I have, and I have had a lot of problems with my masks.
I have somewhat strong lenses ~-4.5 in both eyes and the lenses are thick, yes. Gunk gets into the grooves because the lenses jump so high up. However they feel superior to the other Rx lenses I have, brighter somehow. Also the downward view is maximized with the Rx lens reaching as far as possible in every direction. Not like with some other made-to-order lenses where the Rx part is glued only to cover the very middle part of the glass.
The other great thing about the Atomic is that the silicone is very very soft, sealing in superior fashion. I have used mine now for about 3 years and it's holding on great. The strap/buckle system is also something I like better with this mask than my others, very smooth operating.
If you have poor eyesight it's well worth getting mask in your own strengths.
