My view has gotten poor over the years, I am 53 and I need glasses to see small things close up. My vision far away is fine. I do not own any scuba equipment, nothing. I was thinking of getting some eye lens so that I can put them in any mask I use while scuba diving. I only go scuba diving 1 time a year while on vacation. So I did not want to get a mask specially made for my vision, since my vision might change year to year. Are there any companies out there where you can buy reasonably priced lens for a scuba mask? Any pros or cons about doing this? Any advice?
