Hi Jake,

Here I just have a follow-up and want to double check with you so I understand it correctly.

1. Double check if I did the normalised diopter correctly. Say the differential is -6, then the normalized should be either -7.5, or the one gives 20/30 on snellen chart, right? It should NOT be -4.5 (-6 + 1.5), right?
2. What I do now is wearing differential for close-up, like screen-work, reading, cooking etc. For outdoor, and at night when I need clarity at longer distance, say TV, I use normalized one. Let me know if this sounds good or anything wrong here.

Thank you very much!
