could light sources from our surrounding hurt / damage / affect our eyes ?

I don't mean UV / Sunlight that we all know that they will hurt our eyes by common sense.
I am living in densely populated city where I could often see strange colored light from unknown sources. They are NOT from advertising windows or storefront or automobiles. They could be from unknown devices. For example, today I saw a pedestrain holding something and pointing it to the upper direction which emits strong green light, I wasn't sure what it was, I turn my eye away quickly, I want to get close to him to see what it was, but he then left quickly.
I think I am sometimes overreacting, however, for long we know that LASER could damage
our eyes permanently and everyone of us could easily get a pocket LASER legally.
I have two questions
Should I worry about colored light from unknown sources in my city? Could those light hurt / damage our eyes or worsen myopia?
How to know if light from a source is LASER or not? Does LASER only appear as a form of beam? If the light is not a beam-like, then it's not LASER. Am I correct?
If every time I find strange light or strong light, then I look away immediately, could a few seconds of looking at those light be bad enough to do some harm to our eyes?
Any other comments, discussion and information are always welcome

Hi, I am afraid I cannot answer your question. I live in the country where there are not a lot of unusual light sources. i had a laser used on my eye yesterday which helped my problem. but I guess you do have to be careful about them. i have been advised to protect my eyes from the sun. I hope someone can give you some answers.
