The eclipse can never be observed by naked eyes, but the professional eclipse glasses sold online are expensive. According to the experiment, I made a pair of observation glasses, which is convenient to take, and everyone can try it.
The production process is:

  2. Cut into a frame of glasses with cardboard.
  3. Apply the blackened plastic sheet to the cardboard frame with scotch tape.

What is the principle of looking at the eclipse?

Look at the eclipse of the eclipse, you can make it yourself, but there are also manufacturers, but they are all similar.
The self-made black platter can be cut out as a lens by using a computer floppy disk, and the eyeglass frame can also be used with clear glass to smear the ink.
The principle is simple. Most glasses are dark or black. According to the principle of the lens, such as a red lens, the transmitted light is red, the light of other colors is absorbed, the light transmitted by the green glass is green, and the different wavelengths are absorbed.
In the same way, everyone knows that black is produced because the light is dim or no light, so the black lens causes the glass to absorb most of the light and light of various wavelengths.
Why do you want to absorb it? The sun is very strong, and looking directly at the eyes can cause temporary blindness of the eyes, decreased vision, and life-long severe blindness.
Therefore, the eyes of the eclipse are made of black or dark to absorb most of the intense light and protect the eyes.
