I’ve worn specs since I was about 5 or 6, they are, for better or worse, part of who I am in terms of looks. The only time I don’t need them, in fact they get in the way, is when I’m doing really close work and then it’s a joy to dispense with them. I wear contact lenses for outdoor activities sometimes. In answer to the OP, yes I do. Do I need them to play? Not really, but if I need to read something or look beyond the stage whilst playing, they’re a necessity.
