Eyes are relatively insensitive, and can be seriously damaged by bright light without pain. If a bright light hurts, it's dangerous. However, just because a bright light doesn't hurt doesn't mean it _isn't_ dangerous. Bright light can, however, cause a flinch reaction without being dangerous. This reaction isn't meaningful without a complete description of the circumstances.
