No! You are simply taking advantage of your natural focal point. However, if you are using both eyes and focusing in at 8", the extra-ocular muscles involved in converging both eyes together to allow for binocular vision at that close range will suffer some strain after prolonged viewing. This is not harmful though.

John, I would suspect your RX to be in the -6.00 to -8.00 range?

Cheers!
