Review (2/5): Would be nice if they had holes to see through so you could use them with the eye masks that have holes to see
This would be a better product if they made some WITH holes and some without holes.
As they are, they interfere with the movement of your eyelashes and so are not entirely comfortable.
They have slits in them so they don't block out light completely, so I don't know what the purpose of the slits is.
