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
Just rotate them 90° and you can see what gets filtered. Been using them for years. I can see where dark sunglasses of any kind can be potentially dangerous in less than bright daylight but one could plan ahead and keep a lighter tint set or one with those photochromic lenses.
polarized during the day, any old safety glasses at night if it’s dusty or there are bugs flying around.
