I should note that in about 350 rounds yesterday, I did not have any malfunctions. One of several casings that landed in my left shirt pocket did scorch it. That left shirt pocket does seem to be a pretty consistent place for casings to land with this particular gun.

Three weeks ago I saw a girl shooting a new Glock G17 at the range. She was bobbing and weaving like a boxer to avoid brass hitting her in the face without thinking about it. Watced a young man shoot his new G19 yesterday. Every time it hit him in the face or the head he shook. A natural reaction.
Before I got rid of my last Glock it hit my safety glasses so hard it made a dent in them (Federal HST 124gr. +P). When I posted this on Glock talk some called me a liar even though others chimed in with similar results. One guy has even posted pictures of the cuts in his forehead from the errant rounds.
Anything hard enough to put a mark in polycarbon safety glasses and hot will do major damage to an eye. Argue what you will. In a gunfight things have already gone to hell fast! Why would anyone in their right mind pick a handgun that might degrade their ability to fight even further than it already is because of adrenaline dump, fight or flight, fear and so on?
A slight poke in the eye, even a flick causes temporary (or permanent depending on the force) intererence or loss of vision, pain,
and extreme watering of the eye. That's why you can't use eye pokes in Martial Arts, Wrestling, MMA, or whatever. It's only for the street. So do you want to inflict an eye poke/gouge to yourself in a gunfight?
The solution is simple. Buy an XD, M&P, PPQ, HK, Beretta, Sig, or any other decent quality gun and it's a non-issue. They don't bite their owners. You might still win a gunfight with a damaged and burnt eye. But why in the hell is anyone trying to make it sound like damaging an eye (even if you win the gunfight) is not a problem?
Just so you can use your Glock? Tell you what. Just take you fingernail and scratch your eye. Especially the colored part. See how bad it hurts and interfers with your vision.
It's like saying my Doberman Pincher is a good protection animal. He bites me regularly. But if I'm ever attacked he'll bite the bad guy in between nipping me. I think you'd get a new dog!

I believe that eye damage would be highly unlikely. The velocity of an ejected casing isn't going to be high enough to exceed a person's blink reflex. Eyelid might get burned, seriously doubt eye damage.

Watching my video with the case extracting into my eye it happens so fast my blink happens after it hit my glasses.

Thanks gents! As a Glock newbie and Gen 4 initiate, I don't have to panic the first time this happens to me!

Just to avoid a long typed out definition by me, this is from Wikipedia:
http://en.wikipedia.org/wiki/Corneal_reflex

The corneal reflex, also known as the blink reflex, is an involuntary blinking of the eyelids elicited by stimulation of the cornea (such as by touching or by a foreign body), or bright light, though could result from any peripheral stimulus. Stimulation should elicit both a direct and consensual response (response of the opposite eye). The reflex consumes a rapid rate of 0.1 second. The evolutionary purpose of this reflex is to protect the eyes from foreign bodies and bright lights (the latter known as the optical reflex).[1] The blink reflex also occurs when sounds greater than 40-60 dB are made.[2]

Use of contact lenses may diminish or abolish the testing of this reflex.

So....a blink reflex usually happens if something actually stimulates the cornea, although it is possible that a person could react to loud noises and also if something comes towards that person's eye and they see it.

The key is that you have to see it coming to blink before it hits you in the eye. Despite much slower velocity, people get poked in the eye by tree branches all the time because they never saw it coming. Once they get poked, the blink reflex causes them to blink and jerk away, reducing the damage, but damage may still occur despite the reflex.

After installing a WSD HRED on an erratically ejecting/failure to ejecting G19 I have, the casings actually came back at my head faster and harder to the point where it hurt. I eventually got the gun to eject more consistently (and 100% reliable with 2500 rounds since) by switching to the Lone Wolf extractor, modifying the ejector, and keeping the WSD HRED in the gun.

Nah. A large, light, low velocity object coming right at the eye...corneal damage unlikely, but I'll grant you that anything is possible.

HMAC - my 3rd Gen G19 would eject brass to 6 o'clock hard enough that if BADLY scratched the lenses of my Oakleys; and the brass frequently hit my forehead hard enough to leave bleeding cuts.

I'd guess that if I caught one of those directly in the eye, it would have caused damage...
