Millions of people in a minority group in North America will look up as the sky darkens. total eclipse on April 8. If he does. safety is important.

Looking at the sun during an eclipse or at any other time can cause permanent eye damage. The eclipse is silent safe to witness with the eyes at all timesor a period of total darkness when the moon completely covers the sun.

Those who love know the eclipse they should buy eclipse glasses from reputable retailers. Sunglasses are not protective enough, and binoculars and telescopes without a proper solar filter can magnify sunlight, making them unsafe.

“Please put those glasses on,” said NASA administrator Bill Nelson.

Where to get eclipse glasses

Since fake glasses are common, consider buying glasses from a science museum or ordering them online from a seller listed on the American Astronomical Society website.

Eclipse protection experts say approved eclipse glasses must block the sun’s ultraviolet rays and nearly all visible light. When worn indoors, bright lights should be seen in depth – not furniture or wallpaper.

Vintage eclipse glasses from 2017 total solar eclipse or October “ring of fire” annular eclipse they are safe to use again, as long as they are not bent and have no scratches or holes.

Glasses must state that they comply with ISO 12312-2 standards, although fake sellers can also print this language on their products. NASA does not endorse or certify eclipse glasses.

How to watch the eclipse without glasses

If you don’t have eclipse glasses, you can enjoy the show through indirect methods like making a pinhole projector using household items.

Punch a hole through a piece of cardboard or cardboard, hold it up during the eclipse and look down to see the small piece below. Carrying a colander or a cracker produces the same result.

Another option: Looking down on a shade tree can create shimmering shadows as sunlight hits the branches and leaves.

Ophthalmologists are warning against viewing the eclipse through a phone camera. Sunlight can also damage the phone’s hardware.

Why eclipse viewing is dangerous

Eye damage can occur without proper protection. Sunlight can burn the retinal cells in the back of the eye. The retina has no pain receptors, so there is no way to detect damage as it occurs. When cells die, they don’t come back.

Symptoms of sun damage to the eyes, called solar retinopathy, include blurred vision and color disturbances.

In a rare case of eclipse eye damage, a woman who saw the 2017 eclipse without proper protection came to Mount Sinai’s Eye and Ear Infirmary, complaining of black spots in her vision. Doctors found retinal damage that was similar to the eclipse.

Dr. Avnish Deobhakta, an ophthalmologist at Mount Sinai, said: “The dark spot he was describing was like a small particle.

There is no rule as to how long a focus can last. Risks vary depending on cloud cover, air pollution, and perspective.

But doctors say watching the eclipse for a few seconds without protection is not recommended. There are reports of solar retinopathy after each eclipse, and eye doctors in the US saw more visits after the 2017 eclipse.

Observers who plan ahead can watch the eclipse worry-free.

Dr. Geoffrey Emerson, a member of the American Society of Retina Specialists said: “It can be dangerous if we are not careful, but it is also very safe if we take precautions.”
