A total solar eclipse will take place on August 21, 2017, and millions of people across the United States will be able to witness the celestial event. Named the #Great American Eclipse, the event can be witnessed from quite a few places in the U.S. Residents of Idaho, Oregon, Wyoming, Nebraska, Illinois, Missouri, Tennessee, Kentucky, South, and North Carolina will be able to see the #Total Solar Eclipse. However, it is of utmost importance to take precautionary measures before witnessing this once in a lifetime phenomenon.
Protect your eyes during the upcoming solar eclipse
As we all know, a solar eclipse takes place when the sun and moon align with each other in a straight line while staying in their respective orbits.
According to scientists at NASA, stargazers should look directly at the eclipse with bare eyes only during the totality and not before or after the occurrence of the event. However, if one risks looking directly at the sun without protection before or after the totality, they may risk damage to their eyes. Looking directly at the sun during a solar eclipse may cause something known as solar retinopathy.
How to protect eyes during the solar eclipse?
NASA, the #American Academy of Ophthalmology, the American Astronomical Society, the National Science Foundation, and the American Academy of Optometry have laid down some common ground rules one must follow while witnessing a partial or total solar eclipse. According to the above-mentioned institutes and agencies, one must use either solar filters or handheld solar viewers to look safely at a partially eclipsed sun. However, home-made solar filters or even ordinary sunglasses – despite their darker shade – are not safe for looking at the sun directly during the celestial event. Apart from this, one must also not use a telescope, camera, or any type of optical device – unfiltered or filtered – to look at the sun.
