I love this product. You can wear it extremely lose and it still works fine. And it has a great band that won't give you a headache and that you can tighten as much as you want. I rest it on my lower eye socket and let it go above my eyebrow. It doesn't bother my eye lashes, and I have long ones, but they do touch. You can see through them but they are cloudy, which I like. I can see well enough to go to the bathroom, but I won't wear them to work my mistake, which I would if they were crystal clear. I bought them because my CPAP machine caused the top layer of cells to die in the middle of my eye by blowering air on it. It hurt really bad and I was unable to work. Luckily the eye doctor gave me some ointment with cortisone that healed it enough to work within one day. But it also caused painful lumps in my breasts, so don't use the ointment unless you have to, and then only as directed and for a small amount of time. It also caused major depression getting off the cortisone for a few days. The eye shields work well and make me feel safe. I refuse to use my cpap machine without them. I tried other cpap masks and nothing worked well. This was the only workable solution, and one that I really like.
