A myopic person uses his ideally prescribed eyeglasses that have a refractive power of -2.3 diopters. What is his far point distances if he wears his eyeglasses a distance of 3cm from his eyes

(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…

Your mother (without glasses) can see things clearly only if they are between 26.0 cm and 167 cm from her eyes. (a) If her glasses are to sit 2.20 cm from her eyes, determine the refracting power needed for glasses that will correct her myopia. (b) Determine your mother's near point when wearing these glasses. cm

Suppose a person's eyes have a relaxed power of 50.62 D. Assume a 2.00 cm distance from the retina to the lens of the eye.    What is the far point of the person in m?

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?

A farsighted librarian wears her 3.84-D refractive power eyeglasses 0.0300 m from her eyes and is able to read books held no closer than 0.264 m from her eyes. As a matter of convenience, she decides to switch to contacts. Determine the refractive power for her contact lens prescription.
