Surya Grahan: Solar Eclipse 2021, Skygazers treat | Can it also cause blindness?

Solar Eclipse: People in the southern hemisphere will be to see a total or partial solar eclipse tomorrow on December 4.

It will be the day when the moon moves between the Sun and Earth. Also, it will be this year’s last.

A big feast for the sky gazers-the moon will fully or partially cover the sun’s light in the southern hemisphere.

This way it will be casting a shadow in some areas on our planet earth.

It is worth mentioning here that Antarctica will be the only place that will experience a full solar eclipse.

The Sun, Moon, and Earth will fall in a direct line. While, in some other places, viewers will see a partial solar eclipse.


Those living in Saint Helena, Namibia, Lesotho, South Africa, South Georgia and Sandwich Islands, Crozet Islands, Falkland Islands, Chile, New Zealand, and Australia will only witness a partial Surya Grahan.

But several viewers will need to get a clear view of the horizon in order to see the solar eclipse; it is because, at several locations, it will occur before, during, and after sunrise or sunset time.

But technology has made it easier for all of us to see Surya Grahan via a live webcam these days.

NASA will also live stream the total solar eclipse from Union Glacier, Antarctica on YouTube. Viewers may also watch it on

However, sky gazers are always advised to never look directly at the Sun. The viewers must wear solar viewing or eclipse glasses for the same.

Watching solar Eclipse with naked eyes can cause blindness?

Viewing a total solar eclipse may not cause any harm but watching a partial Surya Grahan can badly damage your eyes.

Watching Surya Grahan through the naked eye can cause a central retinal burn.

As per scientists, humans can’t stare at the sun through naked eyes. This is because of intense light released by the sun which eventually causes immediate eye closure.


But during a solar eclipse, the intensity of sunlight is decreased significantly which means humans can then see the sun through naked eyes. But while watching the sun through naked eyes, the ultraviolet rays (UV) penetrate our eyes. This can lead to loss of central vision.

This damage can happen without any pain. In fact, the damage could be visible after a few hours or even a few days after viewing the Surya Grahan.
