The number one rule for watching the solar eclipse on august 21 is not to look directly at the sun without special eyewear, even when it is partially obscured, said Jim Lattis, who directs the University of Wisconsin-Madison's astronomy outreach center Space Place.
As the total solar eclipse approaches, demand for safe viewing glasses has spiked and experts are warning the public to be wary of risky knockoffs.
"It's going to traverse the entire pass of the United States", Kopernik Observatory Executive Director Drew Deskur said. Tens of millions of people who live within a 70-mile radius of its cross-country track will witness the eclipse in totality (the sun completely blocked by the moon) while millions of others outside of it will enjoy a partial eclipse. But if you live anywhere in the US, you'll be able to see a partial eclipse, which means you're in for some breathtaking sights as the moon partially obscures the sun. If you are planning to watch the solar eclipse on August 21, there are some things you need to know to be prepared. The tech giant has promised to ship some 2 million glasses to 4,800 public libraries across the USA, all in the hopes that as many kids as possible will get to see the moon crossing directly in front of the sun.
"Even at maximum eclipse it is not safe to look directly at the sun", Violet Mager, assistant professor of physics and astronomy at Penn State Wilkes-Barre, said in a statement. Jay Pasachoff says that he often gets asked why they still are so excited about the eclipses, through the scientific paradigm.
The proper lenses should meet what's called "ISO 12312-2" (sometimes written as "ISO 12312-2:2015") global safety standards, according to the group. Contact local science centers and museums if they have any eclipse viewing glasses available. The times of darkness from the eclipse will shorten as you move away from the path of totality, with the areas the furthest away experiencing on a few seconds of darkness.

Eye Care Specialists, which has locations across Luzerne County, also pledged to give out free eclipse glasses to anyone who stops by - while supplies last.
"Do not use a camera, set of binoculars, telescope, even your cell phone, do not view through these even if you're wearing the ISO stamped approved protective eye wear, " Ross said. The glasses should not allow anything through except light from the sun or something similarly bright, such as a bright halogen light bulb, according to the society. "We'll be handing out glasses there and there will be food trucks and a big jumbo screen that will be broadcasting footage from a total eclipse". Over the years, he's journeyed to North Carolina (1970), Turkey (2006), Romania (1999) and Nova Scotia (1972) - the latter eclipse made famous in the Carly Simon song, "You're So Vain".
Just to make it clear, lighter dots mean less cloud formations and darker dots mean higher chance of cloud formations.
