Comfortable and cool. I have trouble taking these off when they arent necessary lol. The color and polarized lens definitely gives relief when its bright out. When I first put these on, my face immediately bacame relaxed. It was like a whole bunch of weight fell of my face. I can wear these all day until its absolutely too dark to see, but whats interesting is you can still see clearly in a low lit environments. Dont ask how I know. ENJOY!
