Uncomfortable for side sleepers
I purchased this product to replace another sleeping mask that had come apart over time.  This product appealed to me because of its promise to block out all light and not to put pressure on my eyes.  It does a good job of blocking light, but it is the least comfortable sleeping mask I've ever owned.  The padding around the eye socket that blocks the light and prevents the mask from pressing directly on the eye is very rigid.  It puts an uncomfortable amount of pressure on the bridge of my nose, and shifting this to make it more comfortable allows light to come in.  As a side sleeper, though, the worst part of this mask is the small metal piece on the band that allows the band to be adjusted.  When I lie on my left side, the metal piece presses against my temple.  The padding around the eyes of the mask also press into my face when lying on my side.  I've taken to wearing the mask "inside out" as a last resort while I wait for a new mask to arrive.
