Behind the anterior chamber is the eye’s iris (the colored part of the eye) and the dark hole in the middle called the pupil. muscles in the iris dilate (widen) or constrict (narrow) the pupil to control the amount of light reaching the back of the eye. directly behind the pupil sits the lens. the lens focuses light toward the back of the eye. The following are parts of the human eyes and their functions: 1. conjunctiva. the conjunctiva is the membrane covering the sclera (white portion of your eye). the conjunctiva also covers the interior of your eyelids. the conjunctiva helps lubricate the eyes by generating mucus and tears. it also aids in immunological monitoring and prevents.

Choroid – this is made up of a layer of blood vessels that supply oxygen and nutrients to the retina. defect in the chm gene can cause choroideremia, leaky blood vessels can expand in the retina causing wet age related macular degeneration (amd) and diabetic retinopathy. retinal pigment epithelium – this is a single layer of cells that. The eye is a sense organ containing receptor cells which are sensitive to light intensity and colour. the purpose of the eye is to receive light and focus it onto the retina at the back of the eye. there are two main functions of the eye: accommodation to focus on near or distant objects. adaptation to dim light.
