Doesn't block out the light
This is a nice eyemask for someone who travels, but isn't wonderful for regular use (it doesn't provide any cups for the eye to keep eyelashes from brushing the fabric).  It also doesn't block out all the light, so it's useful for a room with some light, but probably not useful for someone needing to sleep during the day.  I found the charcoal filter irritating to the skin.
