How to watch the total solar eclipse correctly?

Precautions:

1. Sunglasses and sunglasses are not specially designed for observing solar eclipses, and can't effectively prevent red/ultraviolet rays from burning the naked eye. Wearing sunglasses and directly observing the solar eclipse will damage the retina, and because the retina will not feel pain, it will not be noticed even if it burns out.

2. During the partial solar eclipse, it is very dangerous to observe directly through binoculars, telescopes and even camera viewfinder. Special filters must be used for visual inspection and photography.

3. It is not advisable to watch the sun for a long time with glasses dedicated to observing the sun. When watching the partial eclipse of the sun, watch it for ten seconds at a time, rest for three or four minutes, and then continue watching, trying to protect your eyes.
