I dive wearing specsavers monthlys, yesterday I started Iantd Advanced Nitrox I did my no mask swim couldnt see a thing once my mask came off except my instructors fins followed them eyes open for a while when he gave me my mask back, still had my contacts in what a result. I have always worn my lens when diving and never had a problem or lost them while diving, but if you plan to do any teaching when you need to remove your mask frequently I would recommend a prescription mask and you get can inserts for almost all masks. |
