Blocks all light and comfortable to wear!
I have never been a good sleeper and usually wear an eye mask and ear plugs.  I purchased this product to see if it will help me sleep.  It HAS.  It doesn't remove all noise, but it muffles everything.  It fits tight to my eyes so no light comes through.  Very comfortable to wear.  The key is to make sure when you wrap it around the back of your head, you connect it right below the hard part of your skull.  I don't know what to call it, but if you feel the back of your head, you will know what I mean.<br /><br />I ABSOLUTELY LOVE IT.  I have probably gotten more sleep in the last few days than I did all last month.
