Better than expected
The black eye mask has foam all around the edges and cuts out all the light. There is enough room inside that I can blink and not feel the mask yet its completely dark. The black mask is actually more comfortable than the satin mask that was also included.  The satin mask seems to have an opening I'm thinking to add one of those cold gel eye masks though the kit didnt include one. It also came with ear plugs.
