Myths are rampant with eclipses. You don't need to stay inside and draw the shades to stay safe Monday, 8/21/17. There's no magically deadly light radiated from an eclipsed sun. It's the same 'ol sun, just with a moon blocking most of its light. This means as long as you're not looking directly at the sun (as is true always) you won't need the special solar eclipse glasses. If you do plan to, "watch the eclipse", do know that sunglasses absolutely do not provide the needed protection. The only case for wearing normal sunglasses to observe the eclipse is if you are looking down at a projection of the eclipse on the ground.
As I wrote yesterday, the only exception to witnessing the eclipse without the need for special solar eclipse glasses is if you observe a projection of the sun from a pin-hole box, under a shade tree or projected down to the ground or onto a piece of paper, from a telescope or binoculars.
It is perfectly safe to be outside and operate as normal that day, whether you choose to wear normal sunglasses or go without any eye protection. Do you normally stare into the sun directly? No. So don't do it Monday either -- unless you're wearing the special eclipse glasses.
Don't mow the lawn wearing solar glasses. Don't drive wearing solar glasses. Don't walk wearing solar glasses. You don't need them unless you're looking directly up at the sun. If you attempt to drive or walk or do anything other than stand still, you'll find yourself completely blinded and inevitably will crash into something.
Now, to review: if you do plan to stare up at that fiery orb in the sky, you must wear your special solar eclipse glasses. Sunglasses will not provide the needed shielding.
