Aug 21 Solar Eclipse in United States – Safety tips and solar glasses

ViewsHeadlines Desk,

Aug 21 Solar Eclipse has excited the entire American continent. Astronomers expect to be one of the most memorable such scenes in a long, long time, though many others are already talking about the apocalypse.

The excitement is palpable all around with people preparing to watch the spectacle in its full might. What common people and astronomers fear the most right now about the 21 August solar eclipse is weather? Many a times solar and lunar eclipses were not very clearly visible due to the fact that the weather played truant and overcast sky didn’t allow the enthusiasts to watch the spectacle.

In United States, it will be complete and total solar eclipse on August 21. NASA has said that the moon will block out the sun completely, as seen from the United States, following a narrow band across the country while the shadow of the moon moves from the west coast to the east.




NASA has said that this will be the first total solar eclipse in the entire US in the last one hundred years. The last such spectacle was observed across United States on 8 June 1918.

NASA says that anyone within the path of totality can see one of nature’s most awe-inspiring sights – a total solar eclipse. This path, where the moon will completely cover the sun and the sun’s tenuous atmosphere – the corona – can be seen, will stretch from Lincoln Beach, Oregon to Charleston, South Carolina. Observers outside this path will still see a partial solar eclipse where the moon covers part of the sun’s disk.

The solar eclipse will not be short and will last for hours, allowing people to watch and enjoy the spectacles for a long time. This celestial event is a solar eclipse in which the moon passes between the sun and Earth and blocks all or part of the sun for up to about three hours, from beginning to end, as viewed from a given location. For this eclipse, the longest period when the moon completely blocks the sun from any given location along the path will be about two minutes and 40 seconds.

Even though it is an eclipse, you should still not look at the sun directly with your naked eyes, since that could damage your vision. NASA has offered a helpful list of things to do and not do for viewing the eclipse.

Despite your enthusiasm to watch and enjoy the eclipse, don’t forget to take necessary precautions recommended for the occasion. NASA asks the people not to use ordinary sunglasses, irrespective of how dark they are and what UV protection they offer, to look at the eclipse directly.

NASA also clearly asks the people to ensure that they and the young children do not use any homemade filters. It recommends to get hold of solar glasses or a handheld solar viewer that will help you watch at the sun directly without damaging your eyes.

The world’s top space organization asks you to clearly authenticate and check the safety standards of the glasses. Many people who claim to produce safe glasses, fail to keep the standard. You need to ensure that such glasses have certification information that conform to the ISO 12312-2 international standard, and that they have the manufacturer’s information printed somewhere on them. However, if the lenses are scratched or wrinkled, or if the glasses are older than three years, they should not be used.
