K, very helpful.
If you wore glasses, you'd get it. It's an almost universal image shown inside of a glaucoma test device, which puffs a quick burst of air into your eye. It doesn't really hurt, but it startles you and initiates your blink reflex and causes your eye to water. The blink reflex part is the kicker, though, because blinking before the test is done will invalidate the test and they'll have to do it again. I've sat there upwards of six times through this torture device. Lately, though, my eye doctors use a bump test after putting numbing drops in the eye. I think it's probably more accurate, and it doesn't initiate a blink reflex like the puff test does.
Why would you do a glaucoma test for glasses? I've been using them for 15 years now and it's the first time I'm seeing that in my life.
It's a common test for general eye health. It's really not about wearing glasses, it's just something eye doctors do to make sure you stay healthy.
