Presbyopia

A natural, age-related loss of the eyes' ability to focus on close objects, typically beginning in mid to late adulthood.

Lens Elasticity

The ability of the lens in the eye to change shape to focus on objects at various distances; it tends to decrease with age.

Cornea

The transparent front part of the eye that covers the iris, pupil, and anterior chamber, contributing to the eye's ability to focus light.
