You can become blind very easy if you stare at the sun or a light for a long time.If you were wondering how this effect happens here is the cause! The sun (or light)burns your eyes which makes you see a black dot when you open them that means if you stare for a little bit longer then you could become blind that instant!I have always wondered why or how the sun could blind you but apparently we figured it out! So from now and on please don’t stare at the sun or a light for a long time because you know what will happen to your eyes! SO DON’T STARE AT THE SUNNNNN!!!!!!!!!!!:)
