Aviophage is right.
The eclipse itself is not the risk. It is simply dangerous to look directly at the Sun for more than a few second. Normally, if you look at the Sun, you have the reflex of turning away.
However, when you know that near is something going on, you may be tempted to hold on looking, in the hope of seeing the eclipse. That is the jeopardy.
It gets even more dodgy when people use devices to clear the sun appear brighter (like binoculars or telescopes).
The rays from the sun are not MORE dangerous during an eclipse. However, they are not LESS dodgy either. The rays from the sun are LWAYS precarious for the eyes if you look at the sun without proper protection.
Sunglasses (even those against UV rays) are NOT proper protection. Smoked chalice is not OK. Using exposed Black & White (or color) film negative is NOT good protection.
Some grades of welder's chalice (e.g., number 13) may be good. Mylar solar filter specially designed for astronomy are also OK.
Most of these replies are wrong!
A totally eclipsed Sun is no hazard at all: the bright photosphere is completely blocked by the Moon, and the wishy-washy coming from the Sun's corona is dim and harmless (and extremely superb!)
The danger comes a moment ago before and purely after totality, when only a watered-down sliver of the photosphere is visible. Because it's a meagre sliver, our normal reflex to look away are inoperative, and so the full radiation from the photosphere falls on our eye's retina. The damage is _not_ from UV (ultraviolet) street lamp, as someone said, but rather from the other come to an end of the spectrum: infrared (= heat). What happens is that the bake from the Sun concentrated on our retina actually COOKS the cell there (yuck!)
What happen on a properly conducted eclipse expedition is that special dense filters are used to judgment the partial phases of the eclipse. Then, at the moment totality begins (Sun fully covered by Moon) someone yell "Filters off!" and everyone removes their filter and looks directly at the eclipsed Sun, one of the most exquisite sights in adjectives of nature. At the wrap up of totality, the Sun breaks through the valleys at the outskirts of the Moon (called Bailly's Beads), and everyone puts their filters support on to view the final phases of the eclipse without risk. I've been on two eclipse expeditions, contained by 1963 and 2006, and this procedure was followed respectively time and everyone viewed adjectives phases of the eclipse in unfaultable safety.
Looking directly at the photosphere of the Sun (the bright disk of the Sun itself), even for just a few second, can cause unchanging damage to the retina of the eye, because of the intense detectable and invisible radiation that the photosphere emits. This defacement can result in unalterable impairment of vision, up to and including blindness. The retina have no sensitivity to pain, and the effects of retinal sprain may not appear for hours, so there is no admonitory that injury is occurring.[31]
Under normal conditions, the Sun is so bright that it is difficult to stare at it directly, so in that is no tendency to look at it contained by a way that might destruction the eye. However, during an eclipse, with so much of the Sun covered, it is easier and more mouth-watering to stare at it. Unfortunately, looking at the Sun during an eclipse is just as hazardous as looking at it outside an eclipse, except during the brief period of totality, when the Sun's disk is completely covered (totality occur only during a total eclipse and just very briefly; it does not crop up during a partial or annular eclipse). Viewing the Sun's disk through any kind of optical aid (binoculars, a telescope, or even an optical camera viewfinder) is even more hazardous.[32]
Glancing at the Sun beside all or most of its disk distinct is unlikely to result in unbreakable harm, as the pupil will close down and muffle the brightness of the whole scene. If the eclipse is close at hand total, the low average amount of light cause the pupil to open. Unfortunately the remaining parts of the Sun are still a moment ago as bright, so they are now brighter on the retina than when looking at a full Sun. As the eye have a small fovea, for detailed viewing, the tendency will be to track the representation on to this best part of the retina, cause damage.
Same as the regular Sun. The Astronomer told his student that he had be studying the sun all year. When the student asked him what he learned, he said, "not to study the sun adjectives day."
No one has all the same given the real intention. It is because UV radiation from the sun (the frequency of light that does the most sabotage to your eyes) does not significantly diminish during an eclipse. So when you look at the sun when it is much more dim (like during an eclipse), your eyes are more dilated and you let within MUCH more damaging UV radiation, and because the sun appears more dim, it seem more comfortable to look at it for prolonged periods.
Through a telescope, you will lead to blindness. Looking for prolonged periods next to the naked eye will grounds temporary color blindness, color blindness and next blindness and cataracts.
You can look at the sun through a telescope that have a special "solar filter" attached to the lens. You can also use the "camera obscura" trick - poke a small pin hole in a sheet of aluminum foil and hold it away from a sheet of dissertation out in the sunlight. When it's surrounded by focus, you can see sun spots and eclipses.
You can also aim the eyepiece of your telescope at a sheet of rag on the ground and it will create a really nice projection of the sun's image on the serious newspaper... just don't look through the telescope to align it next to the sun! Some telescopes have a white viewing card that attaches to your telescope for this severely purpose.
It is exactly like as when the Sun is not eclipsed. The merely difference is that a 99% eclipsed sun can be looked at short feeling headache, but it still have ample brightness to damage your eye. It roughly burns the cells surrounded by your retina where the lens focuses the feathery.
It isn't the eclipse itself that can wreck your eyes, but looking at the sun. Normally the sun is so bright that your eye will not permit you to look directly at the sun. During an eclipse, though, the sun's insubstantial may be dim enough that you can look at it, but still bright satisfactory to injure your eye.
Never look toward the sun except through a solar telescope or a welding costume or welding filter.

You're eye uses a lens to focus an image on the retina, where on earth the sensory cells "see" the photograph and transmit the signals of the image to your brain.
If you've ever used a magnify glass to focus the sun to burn wood, composition, or bugs, well, that's what the lens contained by your eye is doing to your retina.... It isn't a good thought. Even when the sun is partially clandestine by the moon, there is still satisfactory light to spoil your eyes, so... be careful. The best bearing to view an ecclipse is one that we crafted within Cub Scouts - get a huge board, and drill about 1/4" or 3/8" hole, and hold it in the order of 3 feet stale the ground. The image of the sun will appear within the shadow of the board. (It's called the pin-hole camera effect.) Much safer, and you receive to see the ecclipse.
X-ray, radiowaves, ultraviolet rays are other there. Most of the time it hurts to look. Have you ever have welders flash? It sucks, it is a sunburn on your eyes and it hurts to blink.
