Weather of Arabia - For the first time this year, residents of some Arab countries will be able to see the eclipse of the sun on June 21, and the eclipse will be partial in regions and ringed in regions ( learn the difference between the types of eclipses from here) .
But those who watch this heavenly event need to take precautions, because staring directly in the sun can quickly damage their eyes.
Looking directly at the sun is only safe during the short total phase of the solar eclipse, when the moon completely obscures the bright face of the sun, so the only safe way to look directly at the sun during the annular and partial eclipses is through special-purpose solar filters, such as " eclipse glasses " ".
Which countries can you see the annular and partial eclipses from here?
According to experts, seeing the sun with the naked eye during an eclipse can seriously harm the eye's network, as this phenomenon known as "eclipse blindness" can cause temporary or permanent vision impairment, and in the worst case scenarios may lead to blindness.
There are no immediate symptoms or pain associated with damage that may be caused by looking directly at the eclipse of the eye, so it is difficult to know directly if the eye was actually damaged by the eclipse, as symptoms generally begin 12 hours after watching the eclipse, when people wake up in Morning and they notice that their vision has changed.
Yes. People hurt their eyes by watching the sun during the eclipse without filters in earlier times. However, it is relatively rare.
Dr. Ralph Chow, president of the Astronomical Society of Canada and former professor of optics, said that there are no specific data on the number of people with eclipse blindness, but he noticed that after the solar eclipse crossed Britain in 1999, ophthalmologists reported 70 cases of eye injuries, and that the majority of These people watched the eclipse without filters.
In Canada, 20 cases were reported in the aftermath of the total eclipse of the sun in 1979, and Chu noted that half of the cases reported over the years had fully regained their vision over the following year.
