-> Function
- The eye is a photoreceptor (it detects changes in light) type of sense organ
- It converts light energy to electrical impulses which can be interpreted as images in the brain
- It can respond to changes in light intensity and is able to focus and bend light reflected off of objects in the environment and into the eye so that it is produces a discernible image for the brain to interpret
-> Structure
Note that the ciliary muscles and suspensory ligaments encircles the lens. The ciliary muscles are arranged such that they form a ring of muscle which when contracted, tightens (the radius decreases).
