optic zone - the central portion of a contact lens which contains the refractive power and generally corresponds to the central corneal cap posterior apecal radius - this term is generally used in reference to spin-cast soft lenses. the curvature of the posterior surface of the lens changes with the refractive power. the radius of curvature is measured at the apex of the posterior surface. steeper base curve - occurs when the posterior radius of curvature is decreased (i.e. 8.4 to 8.1 mm) flat...

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...

How do we read and interpret a phylogenetic tree? - ANSWERSTo interpret a phylogenetic tree, one should first examine the lengths of the lines. The phylogenetic trees are usually graphed over a change in time, and thus the lines that extend the farthest overtime relate to the extant species. Extant species include the species that are currently alive and reproducing. If the lines end early these species can be determined as extinct, no longer alive and reproducing. Next, one can follow these lin...
