Playing competitively on a weekly basis (Pittsburgh Pinball League in PA, Tales Of The Tuesday Nights in WV) and in various tournaments throughout the year, I have always thought that I played better with my glasses on than I did when I was wearing my contacts. One reason I believe I think this is is that my contacts are monovision contacts...meaning my right eye is my "far" eye and my left eye is my "short" eye, as far as power of the lens goes. That is a far cry from my glasses, which are basically the same strengths in both eyes.
Just wanted to hear what you all that switch between contacts and glasses have to say about the issue...
