Is the total solar eclipse photographed by mobile phone harmful to the lens of mobile phone?

Shooting a total solar eclipse with a mobile phone is harmful to the lens of the mobile phone.

Shooting the sun will damage the lens. The lens of a mobile phone is like a convex lens. If the convex lens shines on black paper with the sun, it will burn immediately. Although the lens will not catch fire, it will also damage the photosensitive element. Because of the damage caused by too strong light to the photosensitive element of COMS or CCD lens, black shadow will appear after taking pictures, which cannot be recovered unless the lens is replaced.

The mobile phone camera is fully automatic. When facing the sun, the camera will automatically shrink according to the amount of light entering, and the aperture in the camera will minimize the incident light, so there is no need to worry about shooting in a short time. But for observing the total solar eclipse, the mobile phone needs to shoot under strong light for a long time, which will definitely cause damage to the camera.

Precautions for solar eclipse observation:

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.
