Structure And Function Of The Human Eye Cornea and lens: there are two lens in your eyes, cornea and eye lens. cornea,the front surface of eye, does more of focusing in your eye. eye lens provide adjustable fine tunning of focus. this is because the cornea air surface has large change in index of refraction, so light bends alot. the power of eye lens is 43 dipoter.

The simplest explanation is that what we see is a result of light entering the eyes through the cornea and lens, which direct and focus the light towards the photosensitive cells (rods and cones) in the retina. rods work in low light, while cones require bright light but give us colour vision. cones provide the details at the centre of our. The cornea, like the lashes, eyelids, and tear fluid, protects the eye from injury and foreign objects, such as dust. it also helps the eye focus by directing light into the eye. the cornea is. Now that you know the names of the parts of the eye, it’s easy to follow the steps leading to vision. cornea: light enters the eye through the cornea. because of the shape of the cornea, it exits pre focused. aqueous humor pupil: from the cornea, light passes through the aqueous humor and through the pupil.

How the eyes work. all the different parts of your eyes work together to help you see. first, light passes through the cornea (the clear front layer of the eye). the cornea is shaped like a dome and bends light to help the eye focus. some of this light enters the eye through an opening called the pupil (pyoo pul). 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.
