Why you should not observe a solar eclipse with your naked eye?

Answer 1

You can see a solar eclipse with the unguarded eye but it not good for the eye at all. Looking directly at Sol any time is not advised. You can reduce the amount of light with several film negatives stacked together. Make a projector using a telescope and view it on a sheet of paper.

Answer 2

In a solar eclipse there are three stages, the beginning, the total eclipse and the end. during the total eclipse the sun is totally covered and during this time your iris opens up totally to have a brighter view in the dark and when the eclipse passes this stage, sun's radiation enter your eyes and since the iris is totally opened, yours eyes get damaged.

Answer 3

You would certainly be able to see the light from the sun through a telescope,

and that's putting it mildly ! But it would be foolish and dangerous to do it.

Have you ever roasted an ant, or ignited a piece of paper, by focusing a tiny image

of the sun with a magnifying glass ? What happened to the ant or the paper is exactly

what would happen to the inside of your eye if you focused the image of the sun on it.

And don't try doing it for just a little "until you need glasses" either. It only takes

a second for the damage to be done, you don't feel it happen, and all you know is

that you can't see anything in the middle any more.

Answer 4

Observing a solar eclipse with the naked eye can cause permanent eye damage or blindness. The intense brightness of the sun during an eclipse can overwhelm the retina, resulting in solar retinopathy. It is recommended to use special solar viewing glasses or indirect viewing methods to safely observe a solar eclipse.

Answer 5

Actually you can, if you also use a curved mirror.
