I'm not an expert on laser pointers, and i just got a blue or violet laser pointer. Not sure which, because my brother ordered it from amazon.com, the title says violet, but i dont know if thats considered the same thing as blue or blu-ray in laser pointers. So one thing i noticed is when i point it at the wall the dot seems very large out of focus, and fuzzy. I heard somewhere that blue lasers appear this way because our eyes cannot really comprehend the color or wavelength or somthing. I also heard that once you use the laser for a while and your eyes will adjust and it wont be fuzzy anymore. Is that true? And would my eyes make the dot appear more big? On my green and red the dots are small, but it has light shining around the dot. The blue or violet one just seems to have one big dot with little light. Fill me in?
