    An optometrist tests a person and finds that without glasses, he needs to have his eyes 15.0 cm from a book to read comfortably and can focus clearly only on distant objects up to 2.75 m away, but no farther. A typical normal eye should be able to focus on objects that are between 25.0 cm (the near point) and infinity (the far point) from the eye. (a) What type of correcting lenses does the person need: single focal length...

(b) What should be the focal length of a pair of contact lenses prescribed to correct this problem? (c) If instead he wears eye-glasses, and they are to sit 2.0cm in front of his eyes, what prescription should they be?

    8. Your nearsighted brother has a far point of 4 m and he wants to see an object 15 m away clearly Assume he will wear his glasses 2 cm in front of his eyes. What is the focal distance (in meters) of the glasses he needs? Hint: Draw a diagram of your brother, the glasses, the object and the image. Use the diagram to figure out whether the glasses have to be diverging or converging. 9. Consider question 8....

    The contacts worn by a farsighted person allow her to see objects clearly that are as close as 25.0 cm, even though her uncorrected near point is 75.0 cm from her eyes. When she is looking at a poster, the contacts form an image of the poster at a distance of 162 cm from her eyes. (a) How far away is the poster actually located? (b) If the poster is 0.310 m tall, how tall is the image formed by...

    With a near point of 12.0 cm, a nearsighted technician can focus on relatively nearby objects. Yet, with a far point 58.0 cm out, he cannot clearly see distant objects without optical aid. (a) Calculate the focal length (in cm) of a contact lens that would enable this technician to clearly view very distant objects. (Hint: Allow p to approach infinity in the thin-lens equation). (b) What power (in diopters) describes this contact lens? (c) When this contact lens is...
