Review (4/5): it works but fogs up easily
This product gets the job done but it does fog up a lot and the string is pretty tight unless I just have a huge head lol. I wear it under sunglasses and just pull the patch away from my eye long enough to clear it up. It helps with shielding your eye from wind and the A/C in the car. Not sure why it fogs up but it does get the job done.
