Manta Sleep Mask

Community noted

A sleep mask with adjustable, replaceable eyecups used to block out visual distractions.

Why it's buy-it-for-life

The eyecups wear out but are replaceable, letting the mask itself last long-term; a user relies on it to cut off visual distractions and force focus.
