Thanks for the inputs everyone! However, I think I failed to word my question well. I am wondering what would I check to make sure that it is 'Me' that is not focusing the lens well rather than there being a fault in the 75 or the 90 tripping me up? and how I would check that? This dang neurontin trips me up cognitively in odd ways sometimes. Part of me knows I know what to check and how to check it, but I'm drawing a blank :-). Rather draw blanks than not be able to walk!
