5. A far-sighted person cannot focus on objects closer than 80 cm away, compared to the...
A particular patient's eyes are unable to focus on objects closer than 34.5 cm and corrected lenses are to be prescribed so that the patient can focus on objects 22.0 cm from their eyes HINT (a) is the patient nearsighted or farsighted? O nearsighted O farsighted (b) If contact lenses are to be prescribed, determine the required lens power (in diopters). diopters (c) veglasses are to be prescribed instead and the distance between the eyes and the lenses is 1.80...
Sometimes a person cannot clearly see objects close up or far away. To correct this type of vision, bifocals are often used. The top half of the lens is used to view distant objects and the bottom half of the lens is used to view objects close to the eye. A person can clearly see objects only if they are located between 36 cm and 160 cm away from her eyes. Bifocal lenses are used to correct her vision. What...

A farsighted woman breaks her current eyeglasses and is using an old pair whose refractive power is +5/3 diopters. Since these eyeglasses do not completely correct her vision, she must hold a newspaper 42.00 cm from her eyes in order to read it. She wears the eyeglasses 2.00 cm from her eyes. a.What is the focal length of the lenses? b.Are the lenses converging or diverging? Why? c.How far is her near point from her eyes? d.In order to be...
A near sighted person wears corrective glasses made of a diverging lens with a focal length of f = −50 cm. The result is that far away objects appear much closer, and the person sees this image rather than the actual object. Suppose a 12 cm long pencil is held vertically at a distance of 2.0 m from the person. Determine the height and location of the formed image. (for trig-based physics class)
