i didn't get any puffs of air into my eyes Trav - but he did take photos. so at least they have a base picture to monitor later on. even though mine was clear in December, I have family history of pretty much everything that could go wrong with eyes going wrong somewhere, so i'm not too phased at paying $30 every 12 months to have it monitored... i also have visual field tests every 2 years and glaucoma pressure tests every 12 months. same deal. i'd rather be overcautious where vision is concerned...
