I bought this after seeing all the positive reviews. I've never worn an eye mask before so I didn't know exactly what to expect. I have to say, it's quite uncomfortable to wear. It's mainly the strap. I tried loosening it and that did help a little but it still hurts to wear it. Not only that, I'll wake up in the middle of the night to find that I'm wearing the thing half on my forehead because now it's too loose. I guess I'm not surprised considering the price.
