- Problem 102. My wife Margie has lost most of her accommodation. She has a nearpoint of 130 cm and would like to read as close as 40 cm from her eyes. A) What power reading glasses should Margie use? Assume the lenses in the glasses are 2 cm from the eye. B) What is Margie's farpoint while wearing reading glasses?21.17 An overhead projector with a lens of 35.6 cm focal length is used to throw an image on a screen 1.80 m away. If you consider the lens to be a thin lens, how far is the slide from the lens when the image is in focus? What is the magnification in this setup? Work this problem by ray tracing.(a) If your relaxed eye has a refractive power of 55.1 D, and your lens-to-retina distance is 2.35 cm, determine if you are near or far sighted.nearsightedfarsighted (b) If you are nearsighted, determine your far point. If you are farsighted, determine your near point.cm
- A patient cannot clearly see any object that lies closer than 32.0 cm to her right eye. However, the patient wishes to see objects as close as 20.0 cm with that eye. The patient requests eyeglasses to address the problem. (a) Is the patient nearsighted or farsighted? nearsightedfarsighted (b) If the eyeglass lens lies 2.10 cm in front of the patient's eye, what is the minimum distance p (in cm) separating the lens from an object she wants to see? (Give your answer to at least three significant digits.) cm (c) The patient is unable to focus clearly on anything closer than 32.0 cm to her eye (this being the patient's near point). The image formed by the eyeglass lens must therefore be 32.0 cm from the eye. How far, then, (in cm) would the image lie from the lens? (Give your answer to at least three significant digits.) cm (d) The image lies on the same side of the lens as the original object. Is the image real or virtual, and is its position q positive or…You need to use a 23- cm -focal-length lens to produce an inverted image one third the height of an object. At what distance from the object should the lens be placed? Express your answer with the appropriate units.A nearsighted man wears contact lenses of -3.00 diopters. With these lenses, his corrected near point is 25.0 cm. What is his uncorrected near point?
