I'll give that a go. won't sunglasses make it harder to see though? since sunglasses make things dimmer
I've got cycling glasses where you can swap the lenses, so there are dark lenses for if it's a really sunny day, completely clear lenses for rubbish weather and yellow lenses (still not sure what these are for, glare? making things look brighter?) too
so if you wear the clear lenses you still get protection for your eyes without any change in your vision
