Why can t you just look at a solar eclipse with your eyes?

Although the sunlight is much weaker than usual during a solar eclipse, it can still damage the eyes and damage the cornea if you look at it directly.

Because looking directly at the sun will cause damage to the eyes, although it is a solar eclipse, the damage to the eyes is still huge.

It can be said that a solar eclipse is relatively dazzling, and when you look directly with your eyes, it will damage the cornea of the eye, resulting in decreased vision.

It is important to know that direct solar eclipses are more harmful to our eyes, back destroying our corneas.

While people's curiosity is satisfied, many people go blind as a result of using the naked eye** directly, for example, a few decades ago, dozens of people in Germany were disabled for life because they did not use anything to block the light, and they were accompanied by darkness all their lives.

Even after a solar eclipse, the light emitted by the sun is still strong enough to burn the retina and eyeball after a long look.

If you look directly with your eyes, it may cause damage to your eyes.

A few decades ago, dozens of people in Germany were blind just because they were looking at a solar eclipse with their eyes!

The partial solar eclipse is still very glaring.

1. Special observation glasses: There are special eclipse glasses on the market**. It is good to observe with these glasses and does not hurt the eyes.

2. Imaging observation of small holes: use a needle to pierce a small hole in the paper, and observe the total solar eclipse through the projection of the small hole on another paper surface or other interfaces.

3. Telescope projection: After the image of the sun passes through the telescope, it will be projected on the ground, and the total solar eclipse will be achieved through observation projection. But it is absolutely not possible to directly ** a total solar eclipse through a telescope, which can lead to blindness in severe cases.

The key to taking a good picture of Bailey Bead and the Sunrise phenomenon is to get the timing right, because it is fleeting and lasts for a few seconds at most, so you must start closely monitoring the ground glass on the viewfinder a minute or two before eating and before the light is born, and be decisive when you see Bailey Bead and Sun**, and never hesitate for a moment, and be careful not to forget to remove the filter.

If you do not use scientific methods, it will cause damage to people's eyes, and in the past total solar eclipses, this kind of injury has occurred repeatedly, and some have also caused permanent blindness.

You can't see the total solar eclipse directly with your eyes, you can't see the eclipse with film, you can't see the total solar eclipse directly with sunglasses and binoculars, you can't see it directly with your eyes through these devices, and you can't see it if you are injured.

The correct way is to wear glasses for astronomy to look at the sun; Telescope perspective, so that the telescope is pointed at the sun, to see the light and shadow of the sun through the telescope to the ground; In the small hole imaging method, you can see the image of sunlight shining through the hole on the ground using a small hole on the paper.

If you use the naked eye to directly ** total solar eclipse, after watching it, there will be a black shadow in front of the eyes, or a black area in front of the eyes, which will look as if it is blocked by clouds and fog, and it will be accompanied by discomfort such as visual distortion and discoloration.

It is caused by the infrared rays in the sunlight directly irradiating the eyes. Infrared heat energy is very strong, and can pass through a very thick atmosphere or clouds without dispersion, so when you look directly at the sun with your eyes, infrared light will pass through the cornea, lens, vitreous body of the eyeball to the macular area of the retina, after the light is absorbed by the pigment epithelial cells, it is converted into heat energy, burning the macular area, making the macular area edema, bleeding, and even perforation.

**Without proper protective gear during a partial solar eclipse, it can also cause burns to the retina. No matter how long the retina has been exposed to the sun, this damage can lead to permanent damage to vision. When the retina is burned, we may not feel pain, but this visual symptom will appear at least a few hours after this damage appears, so it is important to take measures to protect your eyes during a total solar eclipse.

No. When observing a solar eclipse, it is important not to use the naked eye directly** to avoid strong sunlight burning the eyes, causing solar ophthalmia and solar eclipsal retinopathy, and in severe cases, it can cause permanent visual damage, even if it is a partial solar eclipse, it cannot be directly observed with the naked eye.

Eclipse observation method.

1. Aperture imaging observation method: Aperture imaging allows sunlight to pass through a small hole, and a white screen is placed 1 meter away after the small hole, so that the sunlight beam shines on the white screen through the small hole and projects a image of the sun. This projection observation method can be taken from local materials.

For example, a board with many holes, a loose and broken straw hat, or even the fingers of both hands can be crossed to project a series of images of the sun on the screen.

2. Telescope projection observation method: you can put the binoculars on the tripod and put the whiteboard behind it, so that the magnified image of the sun can be projected. Never hold a telescope directly to the sun, if you use a telescope to look directly at the sun, be sure to use a filter.

3. Goggle observation method: The most common goggles are the special goggles for welders with a shading number of 14, which can be bought in the welding equipment market.

4. Bard film observation method: Bard film is a metal-coated resin film, which can be used for visual and photographing. It is very thin, the socks are noisy with excellent optical quality, and the Bard film that can be bought at the moment has two densities, one for visual use and one for photographing).

5. Observation of solar eclipse glasses: There are many special observation glasses for solar eclipse on the market, and you must pay attention to the selection of observation glasses when buying a banghong.
