Afarsighted person has a nearpoint of 40 cm from her eyes. she wants glasses that will let her see objects at a distance of only 25 cm from her eyes. determine the focal length of the glasses needed if the glasses are 2 cm and 3 cm from her eyes. (remember, a converging lens has a positive focal length and a diverging lens has a negative focal length.) f2 cm cm submit helo 2) f3 cm cm submit 3) a nearsighted person has a farpoint of 484 cm from his left eye and 634 cm from his right eye. he wants contact lenses that will let him see objects at a great distance. determine the focal length of the contact lens needed for each eye.
