A rare celestial event, annular solar eclipse, popularly called as 'ring of fire eclipse' will appear in the sky this Sunday. A solar eclipse is a phenomenon in which the moon gets between the Earth and the sun, thus casting a shadow over the earth. When viewed from Earth a solar eclipse looks like the sun is being covered by a round dark shadow casted by the moon.
Trying to watch the eclipse without the right precaution and protection could permanently damage one's eye. Here is a list of Do's and Don'ts that everybody should be following while viewing the Solar Eclipse.
