I’ve noticed people who wear reading glasses due to presbyopia often put on and remove their glasses hundreds of times per day. Were differentials ever intended to be used this way?
On the flip side, I’ve noticed my eyes get more fatigued or I feel more dizzy the more often I switch between normalized and differentials in a period of time.
Based on data or consensus of those who came before, I’m wondering if a certain amount of focal plane changes per day or per hour (not an exact number, but a guideline) is known to be too much…or am I just imagining it that it’s making me dizzy the more often I switch?
Or, maybe copying the behavior of presbyopic adults past middle age is not a winning strategy for myopia reduction…
