My main problem with sunglasses is that it often slides off my nose when I’m hiking or taking the dogs for a walk. Constantly pushing it up the bridge of my nose is annoying. Have not had this happen to me, even when I’m sweating heavily. It stays firmly on my face. I have a wide(ish) face and also can tolerate having the sunglasses on even for hours.Purchased for an Arizona sightseeing trip. They fit perfectly, provide great sun/eye coverage, reducing glare and heightening contrast and definition. They are light weight but sturdy, don't fall off when I bend over, slip down in the heat or put pressure on my nose. My eyes never got tired. Perfect!For the price these sunglasses are similar to the Oakley's. Comfortable, lightweight, and fit great.Glasses were light and stylish but did not fit well on me so had to return it.Excellent. Absolutely clear with no distortion. I use these for golf.I was happy that product was not broken and it arrive on timeGreat vision with these sunglasses. No distortion. Very comfortable.Awesome pair light weight durable will be buying again
