It is true that you should not look directly at it with your naked eyes, because the sun delivers more power than our eyes are designed to handle, and it will damage your retinas. Not likely to make you blind, but could cause serious ongoing problems.
In Dallas, the Partial Eclipse begins Aug 21 at 11:40 am. The moon touches the Sun's edge Maximum Eclipse at 1:09 pm. The moon is closest to the center of the Sun. The Partial Eclipse ends at 2:39 pm.
When the moon passes between Earth and the sun, and scores a bull’s eye by completely blotting out the sunlight, that is a total solar eclipse. The moon casts a shadow on our planet. The total eclipse will last up to 2 minutes and 40 seconds in places. A partial eclipse will be visible along the periphery.
