'''What is "close" work?''' Norms minus diffs = the number of diopters you need to convert to find this answer. For example, if your normalized glasses are -5 and your differential glasses are -3.5, then you need to convert -1.5. You should be able to see 66.67cm with -1.50 myopia! That's about 26.24 inches, or a little more than 2 feet. | '''What is "close" work?''' Norms minus diffs = the number of diopters you need to convert to find this answer.
