Hello everyone! I’ve taken a long time to get my first differentials because I wanted to see if I could find the answer to my question on the blog or forum first, and I was a bit busy to do so. I have now looked and can’t find the answer anywhere, so I apologize if I missed it.
I understand that one finds the average of your measurements to figure out your prescription. My question is, how many days’/weeks’ worth of results do I take into account?
