Binoculars and telescopes pointed at the solar and considered by the human eye could cause instantaneous blindness. Professionals who use optical units that have special filters which permit them to view the event by way of their instruments.
Joe Citizen, alternatively, has just a few cheap options that may be simply as fun. I will briefly describe the most popular methods. Photo voltaic eclipse glasses purchased from an astronomy store, a do-it-yourself pinhole viewing box or the cardboard projection method.
Secure photo voltaic eclipse glasses are produced from a scratch resistant, optical density 5, black polymer material. They can remove practically the entire infra crimson, ultra violet and 99% of the harmful visible gentle spectrums. These special Solar Eclipse Polarized Sunglasses permit you to see the eclipse as an orange image. They're cheap, light-weight, and a few manufacturers provide the power to print advertising information in case your group would like to give them away or sell them as promotional items.

Another secure method is to use two items of cardboard in the identical way that the box was used above. Merely take one piece of cardboard and poke a gap in it. Hold the piece with the outlet as much as the solar and allow the light from the pinhole to project an image of the eclipse on to the opposite piece of cardboard. Again, DO NOT look by way of the pinhole at the solar for ANY reason. Unprotected direct viewing of the photo voltaic eclipse could cause everlasting blindness.
