I have a class III laser that I'm doing experiments with. The laser makes a point on a wall. I am starring at this point for extended periods of time. I could potentially star at this point for upwards of 10 minutes at very close range(less than 12 inches). I can't really discern weather or not the point is brighter than an ordinary light bulb or a burning candle. Given the close range and extended period of exposure, is there any danger?
