1. Pupil

   The pupil is a black hole located in the center of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil. The term "pupil" was coined by Gerard of Cremona.In humans, the pupil is round, but its shape varies between species; some cats, reptiles, and foxes have vertical slit pupils, goats have horizontally oriented pupils, and some catfish have annular types. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea. On the inner edge lies a prominent structure, the collarette, marking the junction of the embryonic pupillary membrane covering the embryonic pupil.

Examples of pupil in a Sentence

2. Nietzsche:

3. Saj Khan:

   Dr Homer said. The laser treats only the iris and does not enter the pupil or treat any portion of the inside of the eye where the nerves affecting the vision are located. The company is still in the fundraising stage but hopes to have completed clinical trials within several years. And the cost of turning your brown eyes blue ? Dr Homer says Stroma Medical would charge around $ 5,000( £ 3,120) for the procedure. Industry skepticism Industry reaction to the process has been muted. Ophthalmologists who deal with people's eyes, Dr Homer concedes, have every right to be skeptical for the simple fact they are dealing with one of the most sensitive organs in the human body. Saj Khan, an ophthalmologist at the London Eye Hospital, told CNN the treatment raised some red flags. ' The main concern with any procedure that involves releasing pigment inside the eye is that the pigment can clog up the normal drainage channels which can in turn cause the pressure inside the eye to go up, if that happens significantly enough, for long enough, it's how patients develop glaucoma.

4. Emerson:

   The secret of education lies in respecting the pupil.

5. Publilius Syrus:

   To-day is the pupil of yesterday.
