According to the US space agency (NASA), see or look at a solar eclipse directly without glasses is actually safe.
But, can only be done during a total solar eclipse or when the sun is fully closed. Been 33 years or so, the events of the total solar eclipse on March 9 next enthusiasm would invite people to watch.
However, it is important to know how the correct way to enjoy it, especially the naked eye.
The important thing to note is actually safely view solar eclipse in person, just so you know when to see it.
Sunlight when viewed directly will damage the eyes, so if the sun is not fully closed, it is important to use special glasses.
How to know when to look directly and when to use the glasses are familiar signs at the solar eclipse stage following:
Baily's Beads
At this stage the moon was in front of the sun, but still should not be seen directly, because there are points of light that penetrates the outskirts of the month.
Usually the points of light are called Baily's Beads, alias sunlight through the uneven surface of the moon.
Diamond ring
At this stage in the light continues to move up to the point of almost closed all but one point that looks like a large diamond stones.
Still not safe to look directly at this stage, because they have to wait until all the dots of light was gone.
Full eclipse
At this stage the moon has closed the sun in full and were safely be viewed directly using the naked eye in duration of 1-2 minutes.
However, it remains to be aware of the movement of the moon and always monitor the opposite direction from where a point of light like diamonds had been.
sun crescent
The more engaged, will appear a crescent shaped light shadow of a spot of light in the opposite direction last seen being.
At this stage, special glasses must be worn, because soon the light spot will reappear and the previous stages will be repeated.
