y prof accidentally shined her red pointer at me. She was about 2 meters away from me but I kind of looked at the laser for a few seconds. Will I get permanent eye damage? I'm worried

From Wikipedia: "Studies have found that even low-power laser beams of not more than 5 mW can cause permanent retinal damage if gazed at for several seconds; however, the eye's blink reflex makes this highly unlikely. Such laser pointers have reportedly caused afterimage, flashblindness and glare, but not permanent damage, and are generally safe when used as intended."
So, it is highly unlikely that you will suffer any permanent damage--you would either blink or turn your head long before any real damage could occur. Red laser pointers are almost always of the low power type (5 mW or less). Green laser pointers, however, can be much stronger and are therefore more dangerous. You don't have to worry...
