XVI. Terms and facts:
1. The cornea is the most powerful refracting surface of the eye.
2. Refractive index of the cornea is = 1.376.
3. Index of refraction of the aqueous is = 1.336.
4. Emmetropia is normal vision.
5. Myopia: Nearsighted, image focus falls in front of the retina, a concave lens (-) is used to correct
this condition.
6. Hyperopia: Farsighted, image focus falls behind the retina, a convex lens (+) is used to correct this
condition.
7. Presbyopia: Loss of accommodation due to age.
8. Exophthalmos: Protruding eyes.
9. Enophthalmos: Recessed eyes.
10. Diffusion: Process by which distribution of molecules happens.
11. The retina is an extension of the central nervous system.
12. Dialysis: Water is transferred into a solution of protein.
13. Ultrafiltration: Salt is transferred into a solution of protein. Dialysis in the presence of
hydrostatic pressure.
14. Index of refraction of the lens is = 1.390.
