I went to the opticians a few weeks ago for a contract lense check and I mentioned my eyes felt dry. The optician put some dye in my eye and agreed that I did indeed have very dry eyes. They start drying over after a couple of seconds, other people can get to 8-10 seconds apparently (very impressive of them)
This just got me wondering if I have to blink more regularly than the more wet eyed people? So using the very scientific one elephant...by three elephants I need to blink but I can hold it, by five seconds it's getting fairly uncomfortable but by nine elephants my eyes are burning and I have to give in to the sweet sweet blink.
Anyone else care to join my experiment, am I really the most dry eyed of them all?
