Gbenga needs to get glasses to correct his farsightedness. His eyes currently cannot focus on objects that are within 2.1ft (or 63 cm) of his eyes. This is in contrast to people with normal vision who can focus on objects as close as 25 cm in front of them. If the glasses that Gbenga will get will sit 1.6 cm in front of his eyes, what lens focal length f would correct his vision, allowing Gbenga to focus on objects that are 25 cm in front of his eyes? What is the power P of such lenses? P = diopters The lenses will be lenses.
