A total solar eclipse will be plunging parts of the U.S. on August 21, into darkness as the moon will be passing directly in front of the sun. This event, is referred to as “exciting and profound,” and it is going to be watched by millions of people across the nation, as the path runs from Oregon to South Carolina.
To help watching safely the solar eclipse, NASA and other experts have given lots of tips and guidelines. Yet what happens in case you look directly at the sun and what may be the damage and how to prevent it. It is strongly recommended to use special solar filters such as eclipse glasses to view the partially eclipsed sun or uneclipsed sun.
If your eyes get exposed to excessive ultra violet radiation in a short time, especially during eclipse, you may experience eye sunburn namely photokeratitis. The symptoms of the eyes include red eye, gritty feeling within the yes, a foreign body sensation, excessive tearing and extreme sensitivity to light.
It is best to take proper precautions and to avoid looking directly at the sun during a partial eclipse as it may cause solar retinopathy and cause permanent damage to your eyes. This is mostly caused by light from the sun that floods the retina on the back of your eyeball. The exposure to solar radiation is on the retina causing damage to its light-sensitive rod and the cone cells ignite a series of complex chemical reactions inside the cells.
