Can I wear ordinary sunglasses to watch the total solar eclipse?

Ordinary sunglasses, it is not feasible to draw black ink on the glass, which will cause harm to the eyes.

It doesn't matter if there is no professional equipment. Make a small hole with a piece of white paper to let the sunlight pass through, so that you can see the scene of partial eclipse from the ground. There are really no tools around, you can make a small hole in the sun with your fingers, and you can also see what the sun looks like after being "chewed" from the ground. If you are too busy to bask in the sun, you can also cast a window to observe the shadows under the tree. Also due to the pinhole imaging principle, the sun of the partial solar eclipse is projected through the pinhole between the leaves, and a small point is projected on the ground, and a hole will also be missing.
