Solar eclipse safety tip (know when to use a solar filter)

I can't believe that I have to say this:

It is not a lizardmen enslaving black magician political propaganda ploy that you really should not look directly at the sun without using a filter. It is not a plot to prevent you from becoming enlightened instantaneously.

No, it is medical fact that you can injure your eyes if you look directly at the sun for too long without using a solar filter.

What is too long? A few seconds is more than enough. And you will not feel the damage happening because the part of the eyeball being damaged has no pain sensors. In other words, you will not feel the damage happening.

So is there anytime during the solar eclipse when you can safely look at it without a solar filter? Yes. When it is 100% eclipsed by the moon. And that is the only time. I repeat--the only time that you can look without a solar filter is when it is 100% eclipsed by the moon. 

Outside of that little window, do not look at the sun directly without using a solar filter.

(Why can you do it when the sun is 100% eclipsed by the moon? Because the moon is actually blocking out the parts of the sunlight that can fry your eyes. This is science, not magic.) 

Know when to use a filter!

Even Nazis would cringe if you decided to listen to people telling you that it is ok to look directly at the sun without a filter.

Just because it is happening in Trump country, it does not mean that normal safety rules are optional.
