Binoculars and telescopes pointed on the solar and seen by the human eye could cause instantaneous blindness. Professionals who use optical devices which have special filters which allow them to view the occasion by their instruments.
Joe Citizen, however, has a number of low cost options that can be just as fun. I'm going to briefly describe the preferred methods. Photo voltaic eclipse glasses purchased from an astronomy retailer, a do-it-yourself pinhole viewing box or the cardboard projection method.

They will remove practically all of the infra purple, extremely violet and 99% of the harmful visible mild spectrums. These special Solar Shield Clip On Sunglasses Size Chart help you see the eclipse as an orange image. They are low cost, light-weight, and some manufacturers provide the ability to print advertising data in case your organization would like to give them away or sell them as promotional items.

Another safe methodology is to use two items of cardboard in the identical approach that the box was used above. Merely take one piece of cardboard and poke a gap in it. Maintain the piece with the opening up to the solar and permit the sunshine from the pinhole to venture a picture of the eclipse on to the opposite piece of cardboard. Again, DO NOT look by the pinhole on the solar for ANY reason. Unprotected direct viewing of the solar eclipse could cause permanent blindness.
