Diagram Human Eye Anatomy With Label Royalty Free Vector Labelling the eye. use this interactive to label different parts of the human eye. drag and drop the text labels onto the boxes next to the diagram. selecting or hovering over a box will highlight each area in the diagram. the human eye has several structures that enable entering light energy to be converted to electrochemical energy. 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.
Eye Diagram Discovery Eye Foundation The main function is to refract the light along with the lens. iris: it is the pigmented, coloured portion of the eye, visible externally. the main function of the iris is to control the diameter of the pupil according to the light source. pupil: it is the small aperture located in the centre of the iris. The iris is a flat, thin, ring shaped structure sticking into the anterior chamber. this is the part that identifies a person’s eye colour. the iris contains both circular muscles going around the pupil and radial muscles radiating toward the pupil. when the circular muscles contract, they make the pupil smaller. 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. conjunctivitis, often known as pink eye, occurs when this thin membrane becomes inflamed or swollen. Your eye is a slightly asymmetrical globe, about an inch in diameter. the front part (what you see in the mirror) includes: iris: the colored part. cornea: a clear dome over the iris. pupil: the.
