The air being blown into your eye doesnt hurt, it tickles! Its to test for hypoglaucimia or something (spelt wrong), so its worth getting.
I had contact lenses once, sat down watching TV, or reading a book, or doing something, and it came apart in my eye, quite painful, very eye watering.
Worst part about contacts, where they use a toothpick to roll your eyelid up, or when the optician puts them into your eye, or spending an hour trying to get one in, then finding your eye is so sore you got to take it out, so spending an hour trying to take it out
Laser treatment looks good, they cut open your eye with a laser, so that when it heals it corrects the fault, i'ma stick with being half blind though, but they were right, you do go blind!
And no DJ, you aint getting old, I'm 31 on Monday you wee youngster
