NATS 1870 FINAL EXAM REVIEW ALREADY PASSED through accommodation, your eye can change its refractive power to help it focus images by changing the shape of the lens itself, via attached ciliary muscles contracting or relaxing it (lesson 13) we have blurry vision in water (such as in a swimming pool) because cornea itself is mostly made of water, reducing the difference in indices of refraction (lesson 13) a person born with no (functioning) retina in his eyes would be completely blind (lesson...

Cornea Transparent protective coating over the front part of the eye, where it bends light waves so the image can be focused on the retina. Pupil Iris opening that changes size depending on the amount of light in the environment. Iris Colored part of the eye with muscles that control the size of the pupil in response to light (in bright light the iris contracts to make the pupil smaller, and in darkness the iris muscles relax to open the pupil wider). Lens Transparent pa...
