Inferior tarsus

Looks like

The narrow plate of dense tissue that stiffens the lower eyelid, lying just behind the lash line.

What it does

Holds the lower lid against the eyeball and carries oil glands that coat the tear film.

Keeping it well

Lax lower lids with age can turn out or in; gritty, watering eyes from this can be treated by an eye doctor.
