Optical Lenses while snorkeling?

[DMFender]

I'm going on the Western cruise on 9.25, does anyone know if the snorkel sites on Grand Cayman or Cozumel have Optical Masks for rent? Thanks!

I don't know if they do but I just bought one and they are great. It was only $30. I know some states don't sell them but you could always try. I got mine at Sport Chalet.
