I use 4 or 6 pairs of sunglasses stacked on top of each other, can I observe a total solar eclipse

Oh no, after all, sunglasses are not for looking at the sun for a long time. It can only weaken part of the strong light and microwave, infrared, and ultraviolet rays.

If you don't have eclipse glasses, it is recommended to use welding goggles, after all, the welding light can be weakened.

The following information was found in someone else's.

Sunglasses: This is one of the most dangerous ways to observe a total solar eclipse and one of the most widely misbelieved. Sunglasses and sunglasses are not specially designed to observe a total solar eclipse, and wearing sunglasses directly Sunglasses to observe a total solar eclipse will harm your eyes.

**Negatives: This method has been used to observe total solar eclipses before, but because everyone uses negatives to make different levels and negatives, the safety of observation cannot be fully guaranteed, and this method is not recommended.

Candle blackened glass: This is also a relatively early local method, but there are still problems, due to the degree of blackening, the thickness of the glass and other uneven problems, it is also not possible to completely guarantee the safety of observation, this method is not recommended.

Floppy disk core: blackened glass with candles.

Water poured with ink: Although the water with ink has turned into a black background, it still reflects more sunlight to the observer's eye, which can still cause some damage to the eyes. Not recommended.

For eye safety, please use.

Special sight glasses: solar eclipse glasses (or homemade observation devices filtered through a professional light-reducing film such as "Bard film").

Aperture imaging: A small hole is pierced through the paper with a needle, and the total solar eclipse is observed through the projection of the small hole on another paper or other interface; It can also be observed by crossing two fingers to form a small hole.

Telescope projection observation method: 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.

Welding goggles: There are stores specializing in ** welding goggles. However, it is important to note that welding goggles are not the same as sunglasses, which cannot be used to observe a total solar eclipse.

Landlord, if you can buy it, it's best to buy welding goggles or regular eclipse eyes.

If it's true that time is not in a hurry, there is no way, there is only that. However, be careful, you should never watch it for more than 30 seconds in a row.

Tonight's news said that the retina does not have pain nerves, and even if it was burned at the time, it would not feel pain, but it was not long before there was a problem.

Don't take any chances. I'm going to image with small holes.

It's the piece of paper with a needle in the middle.

It is then projected onto another piece of paper.

Experts say that when it's completely dark, you can see with your eyes a little.

Be careful, beware of impaired vision.

OK. 2 pairs will do.

No, absolutely not, it is easy to hurt the eyes When watching the total solar eclipse, we must choose the correct and safe observation method, and even if the observation method is correct, it should not exceed one minute continuously, otherwise it is very easy to bring permanent damage to the eyes.

Six Wrong Ways to Observe.

1.Many people think that you can use sunglasses or sunglasses to watch it, which is actually one of the most dangerous ways to observe a total solar eclipse. 2.The observation of the photographic negatives that have been used will not be completely guaranteed due to the different levels of negative production and the different degrees of negatives; 3.

The soil method of candle blackening glass cannot fully guarantee the safety of observation due to uneven problems such as the degree of blackening and the thickness of the glass sheet; 4.The use of X-ray negatives is not effective in filtering ultraviolet and infrared rays and is not safe; 5.Some people use water poured ink for observation, and although the water has turned into a black background, it still reflects more sunlight to the observer's eye, and the viewing effect is poor.

6.Observed with the floppy disk core, the ultraviolet intensity is still very high, and it is easy to hurt the eyes.

Six Correct Ways to Observe.

1.Look with welding goggles. Welding goggles are meant to protect your eyes under strong light, and you can use them to look directly at the sun; 2.

Small hole imaging. Two sheets of white paper, one with a neat circular hole on it, one facing the sun and one behind the hole, allowing the sunlight to pass through the hole and image on the other white paper; 3.Shade observation.

During the solar eclipse, the gaps in the shade of the trees will become natural holes, and the small bright spots under the shade of the trees are all images of the sun's holes; 4.Look with eclipse glasses. There are many special observation glasses for total solar eclipse on the market**, but you must pay attention to the choice of regular products (it seems that there is no hurry to buy now); 5.

Telescope projection. Never hold a telescope to look directly at the sun, if you use a telescope to look directly at the sun, be sure to use a filter; 6.Look at it with a camera.

Viewing the eclipse directly from the frame can also hurt your eyes without a filter, so don't try it.

Hope for a good weather tomorrow.

Do you have anything to wear for something that is rare in a century???

Please direct **!!

Is there a problem with your brain on the first floor?

Ordinary sunglasses actually have no effect, and they are also harmful to the eyes.

It's better to buy professional eyes

Do you have anything to wear for something that is rare in a century???

Please direct **!!

Of course you can't pull it, your eyes will be broken.

1. The projection of the sun can be dyed black by ink staining a basin of water**, but it is not recommended, because it cannot effectively filter ultraviolet rays and X

It's okay to just wait, as long as you don't stare at it for a long time.

2. Eclipse: The western edge of the moon is inscribed with the western edge of the earth's umbra, and the moon just enters the earth's umbra.

Eclipse: The center of the Moon is closest to the center of the Earth's umbra.

Light: The eastern edge of the Moon is intangent to the eastern edge of the Earth's umbra, at which point the total eclipse phase ends. Round: The western edge of the Moon and the east of the Earth's umbra.

The fate is cut outward, and the whole process of the lunar eclipse ends.

Whole eclipse growth is actually the process from food to light.

3. The observation site can be on the balcony, window, or in the open air, and the observation sites in the Yangtze River basin of China are the best observation sites.

We should not look directly at the Sun with the naked eye because our eyesight may be impaired as a result, even in the event of a solar eclipse (only in the event of a total solar eclipse). Direct observation of the Sun is safest only when wearing special solar filters, such as eclipse glasses and hand-held solar scopes.

There is also a way to observe a partial solar eclipse - using a pinhole projector. With this device, sunlight passes through a small hole – such as a pencil through a hole in a blank piece of paper, or a gap between two fingers – and is projected onto a temporary screen (a piece of paper or the floor). Remember, you can only look at the screen and not the sun.

Don't look at the sun through small holes, it's not safe.

1. Absolute error.

2. At the beginning, all covered and exposed, that is, the moon has passed, and the demobilization is of course a knot. There will be no difference of a few hours, this time it is longer, about 30 minutes to complete, and the meal is even 6 minutes long, long enough.

3. It can be seen that the observation sites in the Yangtze River basin in China are the best observation sites.

Observation method: There are special eclipse observation glasses, ** is very cheap, 5-10 yuan a pair, but many places do not sell it, you know, these glasses are usually useless. Don't think sunglasses will do, no.

There is another way,It's to cover it with cardboard around the display frequency of a digital camera.,And then just look at the screen**.,It's just that the clarity is not high.。。 I can only understand, who made our conditions bad?? There is also the use of small hole imaging, just a few holes on the paper.

1. The best tool for observing a total solar eclipse is, of course, a professional eclipse scope. The projection of the sun can be dyed black by ink, but it is not recommended, because it cannot effectively filter ultraviolet rays, X-rays, etc., as long as you don't stare at it for a long time.

2. Eating refers to the beginning of the initial loss, which is the partial eating stage. As the moon continues to move eastward, the part of the sun's circle that is obscured by the moon gradually increases, and the intensity and heat of sunlight decrease significantly. When the eastern edge of the lunar surface is intangent to the eastern edge of the solar surface, it is called an eclipse.

At this time, the entire circle of the sun is obscured, so the eclipse is the moment when the total solar eclipse begins.

After the eclipse, the lunar ring continues to move eastward, and when the center of the lunar wheel and the center of the sun are closest to each other, the eclipse is reached. For partial solar eclipses, an eclipse is the time when the Sun is most obscured by the Moon.

After the eclipse, the moon continues to move eastward, and the moment when the western edge of the lunar surface and the western edge of the solar surface are intangent is called shengguang, which is the moment when the total solar eclipse ends. Before the light will occur, the phenomenon of diamond rings and pearls will appear on the western edge of the sun, but they will soon disappear.

Circle After the light is generated, the moon surface continues to move away from the sun surface, and the obscured part of the sun gradually decreases, and the moment when the western edge of the moon surface tangent to the east edge of the sun surface is called a double circle. At this time, the sun takes on the shape of a disk again, and the entire total solar eclipse process is over.

What we call whole food growth is actually the process from eating to light.

3. The observation site can be on the balcony, in the window, or in the open air, as long as the east side is not blocked.

Finally, have a good weather, good luck!

It is dangerous to observe a total solar eclipse if you do not know how to observe it, because the sun emits intense visible light, infrared light and ultraviolet light. Not only can UV light cause sunburn**, it can also cause rapid damage to the retina of the eye. As long as the human eye is directly exposed to the sun for a few seconds, it can cause permanent damage or even blindness.

If you look at the sun through a telescope without proper dimming equipment, the consequences are even more dire.

Partial solar eclipses and annular solar eclipses cannot be taken without special safety measures**. During the partial eclipse phase of a total solar eclipse, even if the surface of the Sun is 99% obscured by the Moon, the remaining photosphere formed by the Crescent Moon can cause damage to the eyes. Do not attempt to visually observe the Sun during any partial solar eclipse, annular eclipse phase, or partial eclipse phase of a total solar eclipse.

Ink observation.

You can take a basin of water, add ink, and see the sun in a total solar eclipse through the reflection of the water surface.

Pinhole projection method.

Using two boards, dig a small hole in one of the boards and let sunlight shine through the small hole onto the other board, and the shadow of the sun of the partial eclipse of the total solar eclipse falls on the clapper board.

Telescope projection.

It's similar to the aperture imaging method, but don't shake your hands, otherwise the shadow of the sun will run back and forth. And never hold a telescope to look directly at the sun, if you use a telescope to look directly at the sun, be sure to use a filter.

Filter observation. Transparent filters allow for safe observation of solar eclipses. The material used to make the filter can be waste film, or it can be made from a broken computer floppy disk core.

It is also possible to take advantage of a special eclipse observation card** for eclipses.

Use special eclipse glasses (can you see the sun with just sunglasses or with the naked eye?) Can the eyes stand it? ）

If you can't get a special sight glass, you can replace it with glasses lenses for electric welding or stacking two old discs.

You can wear sunglasses and a sun hat, and you can wear an X-chip.

Don't you have some glasses that you wear to watch a total solar eclipse in supermarkets now?

If you want to use special goggles, it is like the kind used by welders, a small piece is fine.

Look with your eyes or don't look.

Definitely.

You can use the glass on the mask used by welding personnel, which saves money and has a good effect, and is sold in general hardware stores, one or two yuan a piece, and everything else is average. Go ahead and give it a try.

The windows must be UV resistant.

Yes, because the eyes don't have painful nerves, so even if you hurt your eyes, sometimes you won't notice it, so it's best not to watch the eclipse the way you say.

I'm afraid it will, it depends on whether your car has a film and what kind of film is pasted.

Actually, it doesn't matter if we usually look at the sun, but when you suddenly see the sun from the dark, it will have an impact on the eyes.

When you do it yourself, stick it on your sunglasses with the best film, and you'll be fine. Mainly in the solar eclipse and the rounding stage need to be banded.

The color should be as deep as the protective goggles used for electric drought.

The sunglasses on the market are obviously not good.
