During totality you can look at a solar eclipse beside no protection. I've done it three times with no distrustful effects.
During a partial solar eclipse you wouldn't want to look at the sun for the same purpose you wouldn't want to look at the sun on an average day -- it's too bright to withstand for more than an instant.
I don't see how anyone could undergo to stare at the full sun. It would simply be too painful. If you use filter to make it bearable you own to make sure they filter out any treacherous invisible wavelengths so you don't do damage to your eyes you can't sense straight away.
I suppose it's healthy to tip off people not to look directly at the sun, but I contemplate we go a bit overboard when eclipse roll around.
Never view the sun near the naked eye or next to any optical device, such as binoculars or a telescope!
This is more than advice. Why? As a kid, did you ever pocket a magnifying chalice out into the sun and burn leaves? If so, you probably remember that when the focused sunlight coming through the lens was refracted and concentrated to a small spot, the enthusiasm available there be truly remarkable. Guess what? You have a lens freshly like that within your eye. If you look at the sun, your eye-lens will concentrate the sun's light and focus it to a severely small spot on the back of your retina. This can make happen permanent eye mess up or blindness. Additionally, there are no backache sensors back here so you won't even know it's happening! Have I worried the willies out of you? Good!
There are safe ways to outlook the sun. The simplest requires only a long box (at smallest 6 feet long), a piece of aluminum foil, a pin, and a sheet of white composition.
The length of the box is important. The longer the box, the bigger the pinhole symbol. To find the size of the image, multiply down the box by the number 0.00873. For a box that is 1 meter long, the sign will be 0.00873 meters (or 8.77 mm) in diameter. If your box is 5 foot (60 inches) long, your solar image will be 60 x 0.00873 = 0.52 inches surrounded by diameter. If you want to round things off, the size of the emblem is about 1/100th down the box.
If you can't find a long box or tube, you can tape together two or more boxes to variety a longer one. In the illustrations below, we found that tape together two triangular UPS shipping tubes works well. Of course, if you do this, you must cut out the cardboard at the ends of the tube surrounded by the middle!
I found this at google.com and that is how u should look at a solar eclipse
and a lunar eclipse is simply not bright ample to damage your eye
its just similar to looking at the moon during a lunar eclipse and when you look at a solar eclipse its like looking at the sun.
It is the difference between looking at headlights lighting a garage wall and looking at the headlights themselves - the sun is like the headlights and the moon the wall. An eclipse of the sun is similar to someone (the moon) standing in front of the headlight - if they step aside, you will be blinded (temporarily contained by the case of a headlight). And eclipse of the moon is again resembling someone (the earth) standing in front of the headlight, but this time you are looking at the wall so the shadow make the wall hard to see, but if the blocker steps aside, the wishy-washy level is low.
Der. because you never look directly at the sun. And a LUNAR eclipse is looking at the MOON.
because when a solar eclipse happen, you can still see the sun and during a lunar eclipse, it's just approaching looking at the moon
When you normally look at the sun (not during a solar eclipse), your pupils contract and prevent the excess street lamp energy from hurtful your retina. During a solar eclipse, the direct solar radiation from the sun's chromosphere does not instigate the pupil response because your brain perceives it to be within run of the mill limits. In certainty, the overall darkness will bring in your pupils dilate. Without feeling or knowing anything, your retina will be swiftly damaged if you look at the sun.
A lunar eclipse doesn't event because the reflected insubstantial off the moon is too insipid to do anything, whether your pupils are dilated or not.
Because when you look at the sun, you close your eyes automatically, but in a solar eclipse your pupils get dilated and that automatic close doesn't work, and you see directly at the sun, and the moon doesn't affect you because it isn't making the light, the hurricane lantern is a reflection of the sun's pallid.
because lunar is the moon, it won't wound your eyes
but during a lunar eclipse, you would be looking at the sun, which can damage your eyes.
