I've seen ads touting tactical flashlights, and at least one such flashlight was claimed to be capable of "blind[ing] a bear".
I wanted a reality check, and not specifically whether a sufficiently strong tactical flashlight could temporarily blind a bear. My understanding is that people are more visual than many other mammals, and so on egocentric lack of Theory of Alien Minds, customers targeted by the ads would think "I'm mostly incapacitated when I can't see, so being temporarily blind would be an incapacitating experience to a bear," where for bears sight isn't quite so central and a blinded bear may well be capable of getting to you off of hearing and smell, not to mention even more upset for pain in the eyes.
If you want to be able to defend yourself from a bear, how effective or ineffective would a sufficiently strong tactical flashlight be? Would it be an asset or liability combined with a can of bear spray?
