I don't know why this works but it does
I started using sleep masks after contracting meningitis because light affected my eyes. I bought these as replacement masks and they are amazing. Our bedroom is situated so that when people make a left turn onto our street the headlights come straight in our window. I never realized how much that disturbs your sleep! I've got my husband wearing one now and we both sleep deeper and longer. It's breathable, comfortable, and you don't realize you're even wearing it.
