Question 1: presbyopia

Answer:

difficulty in focusing for near or close vision due to decreasing of elasticity of the lens. can be tested by near point of accommodation.

Question 2: Accommodation

Answer:

the ability of the eye to focus deferentially for objects of near vision (less than 6 m, or 20 feet)

Question 3: In farsightedness the light is focus_______ the retin

Answer:

Behind

Question 4: Hyperopia

Answer:

farsightedness. the image focuses behind the retina. a person have no problem with distant vision, but need glasses with convex lenses to augment or increase the converging power of the lens for close vision

Question 5: external ear consists of

Answer:

auricle (pinna), external acoustic meatus,stapes

Question 6: refracted

Answer:

when light rays pass from one medium to another,their velocity or speed of transmission changes, and the rays are bent or refracted.Question 7: During close vision, the ciliary muscle is _______, the ciliary zonule is ________, lens convexity is _____, and light refraction is ________

Answer:

contracted, relaxed, increased, increased

Question 8: visual acuity

Answer:

sharpness of vision. can be tested with a Snellen eyes chart

Question 9: The "near point" increase with age because the ________

Answer:

elasticity

Question 10: real image

Answer:

the image formed on the retina as a result of the refractory activity of the len

Question 11: emmetropic

Answer:

eye is able to accommodate properly. visual problem may result -from lenses that are too strong or too lazy (overconverging or underconverging, respectively).-

Question 12: passage between throat and tympanic cavity

Answer:

pharyngotympanic (auditory) tube

Question 13: Ear

Answer:

a complex structure containing sensory receptors for hearing and equilibrium.Question 14: during distance vision, the ciliary muscle is______, the ciliary zonule is_____, the convexity of the lens is_____and light refraction is _______

Answer:

decreased, taut,relaxed, relaxed

Question 15: Myopia

Answer:

near sightedness. the image normally focuses in front of the retina. a person can see close object without difficulty. correction require a concave lens which causes the light reaching the eye to diverge.

Question 16: astigmatism

Answer:

irregularities in the curvatures of the lens and/or the cornea lead to a blurred vision problem.Correction--cylindrically ground lenses which compensate the inequality in the curvature.Question 17: A convex lens, like that of the eyes produces an image that is upside down and reversed from left to right. Such an image is called a________image

Answer:

real

Question 18: the lens required to treat myopia is a_______lens

Answer:

concave lens

Question 19: structure composing the internal ear

Answer:

cochlea, semicircular canal,vestibule

Question 20: contains receptor for the sense of balance

Answer:

semicircular canal, tympanic membrane
