It will be horribly painful and you'll probably hear a slight popping sound if you're hit with a true 1W from close up, and even at long distances it's going to hurt like hell and blind instantly.

If i recall correctly, your instantly blinded and struck with pain on the initial flash. It's then followed by severe headaches.
Then after a day or two your vision begins to come back and you'll start to notice the blind spot where you permanently blinded yourself.

I wonder if the day or so long blindness is from inflammation and swelling pressing on the optic nerve?

the general point of eye damage is 25mW/second. so 1 watt= 1000mW. so you've got 25/1000=0.025 second. id say thats a definive YES. permanently. 1.5 watts would be 0.017 seconds. come on, look at the forums. look at the danger that people talk about over and over again on the 445 forum stickies. your 1/10th of a second blink reflex will not help you. is this some sort of a joke?

can 1w of 445nm blind you?
probaly not. I mean they also use laser treatment for curing eyes.
Id say try it out and then report back here.
Also make sure you can blind type first.
and blindy read a pc screen and control a mouse.
I take no responsibility in this good advice.

If you hit the spot where all the nerves exit/enter the eye (ironically your natural blind spot) you can blow you complete eye and really lose nearly all or all your vision in that eye.

Aside from a a few jabs, we're telling (YELLING) you that if you have to ask, don't get one until you have eye protection and fully understand the potential danger of a laser. I tell people the same thing about firearms.
