This astounding astronomical phenomenon attracts many people but if viewed incorrectly, it will be dangerous because the radiation is very strong. If direct observation does not use protective devices, our eyes are prone to ultraviolet rays causing burns of the cornea, pain, loss of vision for hours, or even cataracts and withdrawal yellow point chemistry.

Therefore, the US Space Agency (NASA) issued a series of instructions for everyone to be able to observe eclipses safely. Accordingly, to protect the eyes, viewers of the eclipse are required to wear specialized glasses or watch through the filtered sunlight.
