Looks like
A clear, flexible, bean-shaped disc behind the iris, hung by fine fibres.
What it does
Fine-tunes focus by changing shape, letting the eye switch between far and near.
Keeping it well
Stiffens after 40 (reading glasses) and clouds with age (cataract); cataract surgery replaces it safely.
