Human eyesight deteriorates with age because the essential parts of the eye lose freshness and functionality in time and with extended use. Examples of issues related to decreased function of a specific part of the eye include problems with near-sight vision (otherwise known as presbyopia) and issues reading small text, which is the result of a loss of flexibility in the eye's lens. Age-related diseases can also cause damage to the retina and optic nerve, although age alone does not necessarily damage these parts of the eye.
