I've had to endure wearing eyeglasses most of my childhood and all my adult life. To be very honest, they have been a pain in the ass the whole time. They slide down your nose, catch on things in tight spaces or just fall over the side. I've just forked out some big bucks on all singing, all dancing titanium frames with spring-loaded hinges that flex in 4 axis and have vari-focal lenses. Good stuff and I SHALL remember to swap them over when antifouling! The joyous part of wearing specs? Well okay when with an angle-grinder or airhose at a pinch, but not great. Always put proper protection over them when you can. The down side? Jumping into a Zodiac in Tahiti and watching one of your lenses wibble to the bottom of the harbour, bumping into the owner for 2 weeks while blind and him sending his 737 private jet 8000 miles to go and pick-up some new ones for you. Anyone else have issues with their eyeglasses?
