100% Blackout Eye Mask for Sleeping – 3D Deep Contoured (Discount at checkout) Sold by Zoukali-Store / FBA

Looks like a decent option if youre sensitive to light when sleeping. Its designed to give full blackout and has a 3D contoured shape, so there should be a bit of space around your eyes rather than the mask pressing directly against them.
The strap is adjustable and the material looks soft enough for overnight use. Could be handy for travel, naps or anyone working shifts as well as normal bedtime use.
