I’ve been using 7eye since maybe 2004 in Arizona and the Eye Cups help greatly with the Desert Dust.
The Mistral works so well for me. I own both black and tortoise shell and always get the polarized grey lenses. They do a super job of protecting my aging eyes and minimize the wind exposure.
Fit perfectly on my glasses. Much better quality than the old style foam.
I suffer with severe dry eye and have had multiple cornea ulcers. I can only wear total protection glasses with a prescription and these glasses are awesome! They are very comfortable and light. They are also quite stylish. I highly recommend them to help keep out the wind, dust, air conditioning and fans. They do fog up but I just use an eyeglass anti fog spray on them and they are good to go.
