Great mask. I chose this one because of my light sensitivity and it helped 100%. I did not have any of my usual discomfort snorkeling in bright sunlight.
It fits nice and soft and seals very well.
It provides amazing clarity in the water:
Our local guide lost two banknotes while diving. My wife suggested trying to find them but he was sure it was impossible. Using this mask, after several minutes of search from the water surface I was able to spot the money on the see floor at about 4-5 meters depth and recover it.
