I agree with Andrew that all lasers are dangerous to eyes. But only if pointed directly into eyes. Same with the IR from the cheap lasers noted in the video. As an astro pointer, what we are looking for is the beam that is produced by green lasers, this is the main distinction between what we consider the use of these pointers as opposed to just the bright dot that is being considered in the video. Two very different applications. But this does not detract from the dangers of direct illumination onto skin and eyes.
