Finally got a pair of prescription sunglasses for summer, but apparently polarised lenses are potentially dangerous for cyclists according to Redditors due to light playing weird tricks on you. On my first day wearing them the only interesting thing I noticed was my phone screen shimmering like a foil trading card
I ride with polarized lenses and haven’t ever had any significant issues related to it. Could there exist some strange situation where polarized lenses are not ideal? Sure, that’s plausible I guess, but seems like a weird thing to be concerned about when riding a bike. The cars are much more of a real threat.
The only thing I can think of would be if safety signals were being displayed via LCD screens or some other polarized light source. That could cause some issues, but you just push the glasses out of the way for a few seconds and the problem is mitigated.
