Am I going to go blind?

Okay, so the title was an exaggeration. Maybe clickbait. I can still see. But, after looking at the focus point (not the actual beam pointed at my eye) of a 405nm 150mw violet laser, without safety glasses, I experienced some pain in my right eye. Not that the safety glasses I was using would be any better, I got them for $10 on ebay (but I'm nearly positive they're for the correct wavelength). Any veterans here able to tell me if the pain is serious damage, or just me being paranoid? Any help is appreciated.
:thanks:
