What will happen to the eye, if you look through the telescope at the sun?
The astronomer shows the result of "observations" in practice
From childhood, many of us have heard that no binoculars or a telescope to look at the sun can not - will be damaged eye. All we know why - the sun's rays are focused, and eye tissue can be sure to be damaged. But how can the damage be? The question, perhaps, a little child, but still interesting.
So it is interesting that all of this it was decided to check. Astronomer named Mark Thompson decided to show it in practice. He set 80mm telescope with a 50x increase, pointed it at the sun, and looked through a telescope. However, his eyes he was not endangered damage - instead the Sun "admired" pig eyes.
The structure of the eye pig is quite similar to the structure of the human eye. Therefore, this body is a good demonstration of the effects of observing the sun without protection, unprotected eye. First, sort of like nothing is happening, but after 20 seconds the eye starts to smoke. And this is not par - eye tissues begin to burn.
Within 20 seconds the hole formed in the eye, passing through the cornea and lens. Thompson cut eyes, and found that the extent of the damage is very high - light and struck the deep layers of the eyeball, not only the surface
. What conclusion does the scientist? "It's very, very bad idea to look at the sun through a telescope naked eye," commented Thompson happened. But we do not doubt it, right?
