The focal length of a relaxed human eye is approximately 1.78 cm. When we focus our eyes on a close-up object, we can change the refractive power of the eye by about 16 diopters. Calculate the focal length of the eye when we focus closely.
1/di+1/do=1/f
im not really sure what to do with the diopters. please help me start the problem.
