At daytime, 10m is ok for a short time.
During the night, I'd go with at least 25m.

Some people are more sensitive to bright light than others. My daughter is one of those people, but I have no problem looking at the spot from my Sky Ray 1.7 watt or my 3 watt MS-SSW-II. And that is off a white wall at about 12 feet. It is no longer collimated or in anyway in Phase at all being reflected off of a rough surface, so the damage is more probably imagined. A blond or light colored retina is more sensitive to the brightness of the light. I never have had any damage, and I visit an ophthalmologist every year. She is very thorough and my retina shows no signs of damage.
