Sunglasses heatup
I've noticed that my sunglasses often heat up under sunlight (with their black color as a contributing factor, apparently, up to the point that wearing them becomes uncomfortable). Are there already any ways to prevent excess heatup of black sunglasses (possibly material or coating-wise)? Thanks. 212.180.235.46 (talk) 21:04, 16 June 2020 (UTC)
 * Replace your dark sunglasses with mirror shades. They stay a lot cooler. If you can, get light colored frames on the new ones. --Guy Macon (talk) 21:47, 16 June 2020 (UTC)


 * That’s weird. How old are your sunglasses? Are they off-label?  I’m in the direct, tropical sun every day, and I’ve never once had this problem. Viriditas (talk) 23:11, 20 June 2020 (UTC)
 * Is the frame metal? Metal will transfer more heat to your body; consider switching to all-plastic shades if that's the case. Also wear a light-colored, wide-brimmed hat (not a baseball cap or similar). This is a good idea anyway because it shades your body, which keeps you cooler and reduces sun exposure to skin, which is why health authorities recommend it. --47.146.63.87 (talk) 18:56, 21 June 2020 (UTC)
