Review on ✨ ITSCOOL Polarized Sports Sunglasses: Versatile 5-Lens Shades for Men & Women - Ideal for Driving, Golf, Fishing, Running, Cycling, Baseball by Carlos Macy

They're really good for the price. My "biggest" complaints are the notches on the top of the lenses (I assume this is an anti-fog measure but haven't had a situation where they might fog up) and they fit a bit. I wear 7 3/8 hats. They are dense enough that you can definitely feel them in less than an hour, no problem, between 1-3 hours. Went fishing and wore them for about 5 hours, I couldn't take them off fast enough when I was done. They worried me. They are very light and come with several different lenses which is great. Haven't used them yet, just the ones that came with the kit, the multi colored ones do a great job of reducing glare. I wish manufacturers would go a little further and provide the dimensions of their products and include them in the description. For example, I bet they fit perfectly on a size 7-7 1/4 head. Tolerable for 7 3/8, and 7 1/2 would definitely pinch. Under 7 and over 7 1/2 would be too small and too big.
