how do the lenses of eyeglasses function differently from properly functioning lenses of the eyes?
Answers
Answer:
Here are five ways in which eye lenses differ from eyeglass lenses.
The eye lens is organic, and is made up of lens fibers, a capsule and epithelium. Eyeglass lenses are inorganic, made entirely of glass or plastic.
The eye lens can accommodate (change its shape and focal length). Eyeglass lenses have fixed focal lengths, although they can be manufactured with more than one focal length in different parts of the lens (bifocals, for example).
Eye lenses are biconvex, whereas eyeglass lenses can be either biconvex or biconcave.
Eye lenses are subject to degeneration and diseases (opacification from cataract, for example), whereas eyeglass lenses are not.
The eye lens works in concert with the cornea, whereas eyeglass lenses work alone.
