Sherwood MA50BS Oracle+ Scuba Dive Snorkel Mask, Black Silicone

Worked well as a plain mask but the bi-focal part was useless because it sits so far at the bottom of the mask I couldn’t use it to see anything I was close to unless it was under my chin....

Lenses are so small and so low you can only use 1 eye to try and see anything. Impossible to see with both eyes.Don't buy these.

My husband loves these!! Great product, shipped quickly.
