Hello everyone,
Today I was feeling bored in front of the television and decided to use my 7x50 Fuji's to look at Tolkien's orcs in greater detail. To my surprise, I was able to achieve razor-sharp focus and even had some remaining adjustment range in the individual diopter knobs at a mere ~3m away from the television. I proceeded to test the focus range for several minutes and realized that I could read the small lettering on an Amazon box label (approx size 10 font) less than 2m away.
The min. focus distance of this model is 5m per current Fuji specs, so I know this likely isn't an issue of manufacturing tolerances. With my limited understanding of optical physics, I concluded that it must have something to do with my myopia. As of my last exam in 2018, I have a -3.75 diopter in my left eye and a -4.00 diopter in my right eye.
I believe this is severe enough of a defect to give me a permanent "boost" in close focus distance compared to people with good vision. Of course, the trade-off is I cannot use binoculars with a narrow dioptre range without glasses, as the "negative" correction will often top out long before I get a good view. Have other members with corrected vision noticed something similar with their eyes? Perhaps I should look into insect study. 3
