See the eclipse ~ what do you need to prepare?

Sunglasses. It is a big misunderstanding to observe the total solar eclipse directly with sunglasses. This is because the lens has the function of focusing. When sunglasses are too close to the eyes, sunlight will burn the eyes, and in severe cases, it will lead to blindness. It is not advisable to observe directly with the naked eye. The correct way is to take off your sunglasses, keep one arm away from your eyes and observe the lens from the side. In addition, pinhole imaging is also a good way to observe.

The earliest food:

On May 26th, 65438 BC+0265438 BC+07 BC, people living in Anyang, Henan Province were carrying out various normal activities, but amazing things happened. People look up at the sky, and the previously radiant sun suddenly has a gap and its light color is dim. However, after missing a large part, it began to recover. This is the earliest solar eclipse record in human history. It was carved on a tortoise shell with Oracle Bone Inscriptions on it.

The observation of solar eclipse in ancient China kept the continuity of records. For example, in Spring and Autumn Annals, 37 eclipses were recorded in 244 years from 722 BC to 479 BC. Since the 3rd century, the record of solar eclipse has continued to modern times, lasting for nearly 2000 years.
