Clear glasses: riding at dusk with a decent front light makes one an insect magnet
this reminds me of lel'09 - i had clear glasses for night riding and photochromic for daytime. one night i fell asleep on a bike, went into a ditch.. got up, sorted myself and the bike out, started riding again and after km or two started wondering why my eyes are getting watery. oh no... no chance of finding them then.
photochromic glasses were darker at night, but not too bad. lucky i had them - can't ride without glasses due to sensitive eyes.
