My husband is just starting to fence. He typically wears progressive lenses and is having problems with the (loaner) mask knocking his glasses around/out of alignment. The simple band-around-the-back-of-the-head device for keeping glasses in place doesn't solve the problem. So his instinct is to buy monofocal sports goggles for fencing. Is that a sensible approach? Here I'm asking both about the goggles (vs. contacts, vs better fitting mask) and the switch to monofocal for fencing. (I do it for bowling, but that's a sport where the distances are basically fixed).
