Review on Enhance Your Sports Performance With Xiyalai Polarized Sports Sunglasses - 5 Interchangeable Lenses For Cycling, Running, And More! by David May

I love these! they fit my average sized adult face perfectly. They feel comfortable where they sit on my nose and the arms do not hurt my ears or tug on my hair.I've bought "cheap" sunglasses before and some of them had lenses that warped or they just felt "cheap". The multiple included lenses are NOT warped so my depth perception is not affected. The lenses also have tiny vents on the sides which greatly diminishes (and usually eliminates) the lenses from fogging up.The multiple lenses are easy to switch out and the case keeps everything together. The best part? If I lose them or sit on them and crush them, they will not cost a fortune to replace.
