A solar eclipse is an event when a part of the Earth casts a shadow of the Moon. Due to this, sunlight does not reach the earth in whole or in part. During this time, the sun, the moon and the earth come in line. In a full solar eclipse, the sun completely hides behind the moon, while a partial and anular (like ringed ring) eclipse a part of the sun.
We do not see the Ring of Fire during every solar eclipse and the solar eclipses in which we see the Ring of Fire are called anular solar eclipse. During such an eclipse, the moon covers the middle part of the sun in such a way that its outer edges appear like a ring. Looking at it from a distance, it seems that there is a ring of fire around the moon. However, this ring of fire can be seen everywhere during the annular eclipse. This is the reason that anular or ringed solar eclipse can also look like a partial solar eclipse.
If you are looking at the sky with naked eyes during solar eclipse, the infrared and ultraviolet rays of the sun can damage the retina of the eyes. During this, one should not look directly at the sun for a while. Even though 99 percent of the sun's surface is covered by the moon, the rest of the light is very sharp which can damage the eyes.
