It hurts to wear [SEP] There is a hard sharp plastic covering on the inside that is meant to shield your eyes from the light when you wear it.  This covering digs into my eye lids and underneath and causes a deep sharp line around my eyes.  It make the mask very painful to wear as it digs into my skin like a knife.  I am male with thick skin so if you have thin delicate facial skin I imagine that will cause you a great deal of pain and damage your skin with line marks. I purchased this brand new, but it was not new and was missing the two forhead pads that go underneath as well and there was no user manual.
