ANSWER:
You can burn your retinas and cause blindness.
It's too bright for our eyes. You can burn out your retina and blind yourself.
The Sun is very bright and by focussing the light onto the back of your eye (the retina) with or without a telescope, you are putting a lot of energy (both optical light and infra-red) onto a tiny area. At some point in your life you may have tried to set paper on fire using a magnifying glass, so just think about that being done to the back of your eye. It isn't nice. Even more scarily is the fact that the retina of your eye does not have pain receptors, so you will not even feel the damage being done. It may not even become apparent until later.
It will hurt your eyes! In addition, I think it also may potentially cause you to go blind. The rays are too harmful for our eyes' sensitivity.
Because looking directly into the sun, can damage your eyes permanently.
You could easily lose your sight (go blind) from the concentrated light being reflected back to earth. You only get one pair of eyes ... once their gone, that's the end of your sight ... forever!!
It is dangerous to look a the sun using convex lenses because:
When sunrays hit the lens, the focus increases, as does the heat coming from the rays. The excess heat is suffecient to damage our eye tissues if our eye is the focus of the lens and we may loose our vision. The heat can also burn a piece of fabric of paper.

It is harmful to look at the sun with you bare eyes because it will damge them...............................
Focused sunlight is very strong, and can set fire to paper, as well as destroying your vision if you were so foolish as to look at the sun through a convex lens. Even without the use of a lens, it is not safe to look directly at the sun.
A convex lens.
Bi-Convex lens can be used to focus the Sun's rays
Easy way: Use it to form an image of the sun or moon, and measure the distance of the image behind the lens. When the object is at infinity, the distance between the lens and the image is the focal length of the lens.
Have light from a very distant object directed through the lens onto an opaque, white surface. Change the distance from the lens to the projection surface until the distant object shows a sharp image on the surface. The distance from the lens to the surface at that point is the focal length.

Mermadids do not exist and it is dangerous to look at the sun.
It's dangerous to look at the sun under anycircumstances. The brightness of the sun can cause temporary or even permanent blindness if you look at it long enough ! If you want to view the sun, pierce a tiny hole in a large piece of (preferably black) card. Hold the card so that the sun shines through the hole onto a wall, and view the image there.
The "halo" around the sun or moon is caused by refraction from ice crystals high in the stratosphere (which we look through when looking out into space).
Use binoculars/telescope & a card to look at the Sun. Point the binoculars at the Sun, then put the card behind the one lens of the binocular while the other is covered.
She says it is dangerous "when a man goes outside his home to look for peace."

The sun emits such intense light that it can damage your eyes if you look directly at it.
If you are referring to you eyes, no, definitely not. A SOLAR eclipse is what is dangerous to look at, because the moon is in front of the sun. In a lunar eclipse the sun is in front of the moon. The logic might seem kinda backwards, but it all adds up to the single word that NO, lunar eclipses ARE NOT DANGEROUS.
Because the sun is so intense that sunglasses don't offer enough protection
