Do you also wear contacts? I snorkeled with mine and didn't have any trouble. I just had to be extra careful when pulling my mask off. Matter of fact, I had my son fitted for contacts for this very reason before we went on vacation. He had always worn glasses. Worked wonderfully for him as well. Debbie
here's a cheap and easy way to see while you snorkle if you are not going to buy a mask with a prescription lens; remove the stem pieces (i think that's what you call them)from an old pair of glasses and put the frames with the lenses inside of your mask. it works.
also, i can fix anything on the face of the earth with duct tape. i even taped a duct with it once. just ask me how!!!
I ordered a prescription lense mask at our local dive shop before I went to AC last March for the first time. I have an astigmatism as well as being very nearsighted. From what I understand the rental prescription lenses don't correct for the astigmatism. It was well worth the expense. Have a wonderful trip. Marie
