"So while I was at work today, a coworker pointed a Infrared Thermometer at my eye from 8 ? 10ft/2.5 ? 3 meters away. I don't know how long he had been pointing the laser at my eye for but I realized what he was doing and I directly saw the laser for 5 seconds and it hurt my right eye." -Heinstar Whirlpool Broadband forums.
Although some light might not be visible to humans, all light should be regarded as visible and dangerous.
The danger is however variable, some sources are going to be worse than others.
The critical thing here is what you did immediately after you were exposed to the light.
This is exactly why I created the Universal Solution Law. A simple all-purpose rule that anyone can follow and due to its simplicity is especially suited to an emergency situation.
It reads as follows:
"All problems have an equal and opposite solution which is synonymous with zero."
So, the 'problem' here was exposure to a bright visible light. The 'solution' therefore is the equal opposite of brightness which is darkness. Darkness = zero.
Therefore, immediately after exposure hopefully you sat in a dark room with as close to zero light as possible.
The energy in the form of light that your eyes were exposed to, would shift to and be absorbed by the darkness in the room thereby curing your eyes of that problem.
Obviously it might be a bit late now but good to remember for next time.
