boruch, what a wonderful question you posed. it is brilliantly constructed and a real way to make us all use our minds in a productive manner. i, personally, have had glasses for almost 13 years, and have not yet had the courage to make the step and get contacts. but you, boruch, have begun the process which i have waited a long time for. i think now, after reading this thread, i may be ready.
thank you again boruch and tisku lemitzvot!
