NEED HELP ON #2 A nearsighted pharmacy student has eyes who have a relaxed refractive power of 49 diopters and her retina is 2.3 cm from her lens. 1). If she is nearsighted, what is her far point? If she is far-sighted, what is her near-point? .1804 m 2) Let's say she wants to be able to focus clearly on objects that are from 150 m to 6.5 cm away. What is the power of the corrective lens she should...

A child's far point is 129 cm and her near point is 15.0 cm. In what follows, we assume that we can model the eye as a simple camera, with a single thin lens forming a real image upon the retina. We also assume that the child's eyes are identical, with each retina lying 1.80 cm from the eye's "thin lens." (a) What is the power, P, of the eye when focused upon the far point? (Enter your answer in...

34. In children's eyes, the lens is more flexible than in adults and may be fattened enough to focus on objects that are very close. This near point for one young girl is 8 cm, while her far point (the furthest point she can focus with her lens completely relaxed) is 2 m. The distance from her lens to her retina is 2.00cm a) Between what limits, measured in diopters, does the power of her lens-cornea com bination vary? b)...

A farsighted man uses contact lenses with a refractive power of 2.20 diopters. Wearing the contacts, he is able to read books held no closer than 0.285 m from his eyes. He would like a prescription for eyeglasses to serve the same purpose. What is the correct prescription for the eyeglasses if the distance from the eyeglasses to his eyes is 0.030 m? in dipoters ??? not 1.67 A diverging lens (f1 = −13.5 cm) is located 23.0 cm to...

A certain child's near point is 15.0 cm; her far point (with eyes relaxed) is 129 cm. Each eye lens is 2.00 cm from the retina. (a) Between what limits, measured in diopters, does the power of this lens-cornea combination vary? lower bound diopters upper bound diopters (6) Calculate the power of the eyeglass lens the child should use for relaxed distance vision. diopters Is the lens converging or diverging? O converging diverging
