Binoculars and telescopes pointed on the sun and considered by the human eye can cause instantaneous blindness. Professionals who use optical devices which have special filters which allow them to view the event by their instruments.
Joe Citizen, alternatively, has a couple of low-cost options that may be just as fun. I'll briefly describe the preferred methods. Solar eclipse glasses bought from an astronomy store, a home made pinhole viewing box or the cardboard projection method.
Secure photo voltaic eclipse glasses are comprised of a scratch resistant, optical density 5, black polymer material. They will remove virtually all of the infra crimson, ultra violet and ninety nine% of the dangerous visible light spectrums. These special Solar Shield Clip On Sunglasses Reviews mean you can see the eclipse as an orange image. They are low-cost, light-weight, and some manufacturers offer the ability to print promoting info in case your group wish to give them away or promote them as promotional items. Even though these glasses are safely rated, consultants still recommendation not to view the sun by them for prolonged lengths of time.

If you cannot find a set of Solar Shield Clip On Sunglasses Reviews, then your greatest guess is to make a pinhole viewer. A pinhole viewer is an indirect methodology of viewing the eclipse. It's much safer than any kind of glasses or filter because in an effort to use it, your back is to the sun.

You will note an inverted image of the eclipse projected on to the other facet of the box. (CAUTION: Do NOT look by the pinhole underneath any circumstances. It may trigger quick blindness)
Another secure methodology is to make use of two pieces of cardboard in the identical means that the box was used above. Merely take one piece of cardboard and poke a hole in it. Hold the piece with the hole up to the sun and permit the light from the pinhole to challenge an image of the eclipse on to the other piece of cardboard. Again, DO NOT look by the pinhole on the sun for ANY reason. Unprotected direct viewing of the photo voltaic eclipse can cause everlasting blindness.
