A physicist's right eye is presbyopic (i.e., farsighted). This eye can see clearly only beyond a distance of 87 cm, which makes it difficult for the physicist to read books and journals. Find the focal length and power of a lens that will correct this presbyopia for a reading distance of 25 cm, when worn 2 cm in front of the eye. focal length: cm power: diopters Is this a converging or a diverging lens? diverging converging

A physicist's left eye is myopic (i.e., nearsighted). This eye can see clearly only out to a distance of 35 cm. Find the focal length and the power of a lens that will correct this myopia when worn 2.0 cm in front of the eye focal length: cm diopters power Is this a converging or a diverging lens? diverging converging

A physicist can see distant things clearly when wearing -2.00-diopter eyeglasses. Each lens rests 1.55 cm in front of the eye. (a) What focal length (in cm) describes the lenses? (b) Determine the far point (in cm) for this physicist's eyes. (c) is the physicist nearsighted or farsighted? nearsighted farsighted (d) The physicist decides to replace eyeglasses with contact lenses, one of which rests directly on each eye. What would the contact lens power be (in diopters) in order to...

Your grandfather's left eye is presbyopic. This eye can clearly see only beyond a distance of 89 cm, which makes it difficult for him to read the newspaper. If the printed text in his newspaper averages 3.5 mm in height, how high is the image of the text on his retina if he holds the newspaper as close to his eye as he can? Assume the...

A particular nearsighted patient can't see objects clearly beyond 19.7 cm from their eye. Determine the lens power required to correct the patient's vision and the type of lens required (converging or diverging). Neglect the distance between the eye and the corrective lens. HINT (a) the lens power required to correct the patient's vision (in diopters) diopters (b) the type of lens required (converging or diverging) O converging Odiverging

Goal Apply geometric optics to correct nearsightedness. Problem A particular nearsighted patient can't see objects clearly when they are beyond 24 cm (the far point of the eye). (a) What focal length should the prescribed contact lens have to correct this problem? (b) Find the power of the lens, in diopters. Neglect the distance between the eye and the corrective lens. Strategy The purpose of the lens in this instance is to take objects at infinity and create an image...

A patient can't see objects closer than 32 cm and wishes to clearly see objects that are 18.3 cm from his eye. (a) Is the patient nearsighted or farsighted? (b) If the eye-lens distance is 1.92 cm, what is the minimum object distance p from the lens? in cm (c) What image position with respect to the lens will allow the patient to see the object? in cm (d) Is the image real or virtual? Is the image distance q...

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 person sees clearly wearing eyeglasses that have a power of -3.00 diopters when the lenses are 1.80 cm in front of the eyes. (a) What is the focal length of the lens? cm (b) is the person nearsighted or farsighted? O nearsighted farsighted (C) If the person wants to switch to contact lenses placed directly on the eyes, what lens power should be prescribed? diopters Need Help? Read it
