Difference between revisions of Differentials
m the distance to the object is not the focal distance. (Unless you want to argue that it is the virtual focal distance of the diverging lens that would be required to make objects at infinity appear to be at that distance instead, which is a perfectly valid way of thinking about it.) |

Bearing this in mind, Jake recommends you reduce from your glasses prescription by about '''1.25 diopters'''.<ref name=ChooseReduction /> This will depend on the distance you work from the screen, so reduce it by less if you work farther from the screen. Between 1-2 diopters is a good range - anything more than that and you'll probably want to double check it's a good idea. | ||
