Query: Room darkening eye shades

Fantastic! The sun was shining right in my eyes--too much trouble to close the blinds--so sleeping was a struggle. Put these on, and it's a whole new ball game. They not only shut out all light (comfortably), they rocket you into another dimension. You don't think about your To-Do list and why you should worry about the day that's dawned...your consciousness just kind of...disappears. I highly recommend these magical masks! Just be sure you have a good alarm clock or you'll never know what day or time it is, or which planet you occupy.
