Seeing a solar eclipse can be a very exciting event. There are, however, many precautions that need to be followed in order to view the eclipse safely.
When you look up at the sky to see a solar eclipse, you are staring directly at the sun. If you don’t know already; staring directly at the sun is extremely harmful for your eyes and can cause serious damage and blindness. The sunlight will be focused onto a very small spot on the back of your retina and fry your eyes. There aren’t any pain sensors back there, so you won’t even know that it is happening.
Some ways of looking at an eclipse safely are using quality welding goggles, special solar filters, or using the pinhole projection method. This can be done by taking two sheets of white cardboard and poking a small pin-hole in the middle of one of the boards. Then hold the second board below it and an inverted image of the sun crescent will be projected onto the second board through the pinhole of the first. Be sure that your back is to the sun the whole time and that you don’t look through the pinhole. You may need to adjust the distance of the boards in order to get the best image.
There are also different kinds of filter lenses that you can put on telescopes and binoculars so you can get a nice close up view of the sun without damaging your vision.
There is only danger in looking directly at a SOLAR eclipse. These types of eclipses involve looking right up at the position of the sun for several minutes at a time. LUNAR eclipses on the other hand are perfectly safe to view with the naked eye. The light from the moon during a lunar eclipse is actually just a fraction of the brightness of a regular full moon, so it’s perfectly fine to look at without any kind of protection.
