A:AnswerThe "eye shield" refers to the silicone piece that surrounds the eye holes of the mask. It doesn't block all light, but it does block direct exposure from the LEDs to your eyes. As long as you aren't looking directly into the diodes, you should be good.
A:AnswerThis is not a direct answer to your question, but I put on this mask after showering and doing my evening skincare routine, and it does not produce any extra strain on my neck from supporting the mask. There are no pressure spots, either, that make it sore.
