In bright environments, a significant amount of light can still enter the human eye even through closed eyelids.

This can inhibit napping.

BorgCo has developed an efficient remedy.

Simply have your eyelids tattooed with our new opaque ink. Flesh- coloured, and using metallic pigments that won't degrade or fade over time, it blocks all light from seeping through closed eyelids.

That is all.

The inverse Eyelid_20lenses
[MaxwellBuchanan, Oct 02 2017]

This tattoo could serve double duty and depict sleepless eyes, so no-one would know when you were sleeping and would be (more) afraid to sneak up on you.

Although your glutinous snoring might give it away. A workaround: begin snoring loudly when awake as well, so your enemies never know. You can blame a sinus condition.

Conversely, replacing part of the eyelid with a transparent membrane (possibly with optical correction) would allow you to watch what's going on while you sleep.

The optimal application of this, will of course be temporary tattoos.

That way you can put on the bloodshot ones in the morning, and as they wear you can swap them for the improved models.
