Binoculars and telescopes pointed on the solar and viewed by the human eye may cause instantaneous blindness. Professionals who use optical devices that have particular filters which allow them to view the occasion via their instruments.
Joe Citizen, however, has a few low cost options that may be just as fun. I'm going to briefly describe the preferred methods. Solar eclipse glasses bought from an astronomy retailer, a home made pinhole viewing field or the cardboard projection method.
Protected solar eclipse glasses are constituted of a scratch resistant, optical density 5, black polymer material. They'll remove practically all of the infra pink, ultra violet and ninety nine% of the dangerous seen gentle spectrums. These particular Solar Eclipse Free Glasses 2015 let you see the eclipse as an orange image. They're low cost, lightweight, and a few manufacturers offer the flexibility to print advertising info in case your group would like to give them away or promote them as promotional items. Even though these glasses are safely rated, consultants still advice to not view the solar via them for extended lengths of time.

It's a lot safer than any kind of glasses or filter as a result of to be able to use it, your back is to the sun. (It's arduous to burn your optic nerve that approach) To make a pinhole viewer, simply take a medium sized, rectangular field and poke a small hole within the center of one of many quick sides. Whereas standing along with your back to the solar, put the field over your head with the pinhole aspect dealing with the sun. You will note an inverted image of the eclipse projected on to the other aspect of the box. (CAUTION: Do NOT look via the pinhole under any circumstances. It might cause instant blindness)
Another safe methodology is to use two items of cardboard in the same approach that the field was used above. Simply take one piece of cardboard and poke a hole in it. Maintain the piece with the outlet as much as the solar and permit the light from the pinhole to challenge an image of the eclipse on to the opposite piece of cardboard. Again, DO NOT look via the pinhole on the solar for ANY reason. Unprotected direct viewing of the solar eclipse may cause permanent blindness.
