I was reading a tutorial on taking my PS2 apart (which I followed), and the author made a couple of references to "level 1 lasers". S/he was saying they can potentially blind you, I was wondering if this is actually true or if it's a misunderstanding? I only ask as i've worked with exposed lasers quite a bit and my vision is a-ok (In fact, i'd say I have above-average eyesight, probably equal to that of Superman's).
