Solar Eclipse 2017: Glasses Giveaway

Solar Eclipse 2017: Glasses Giveaway”

As eclipse glasses sell out at retailers across the United States, customers are panicking as they realize that their glasses may not arrive in time for the once-in-a-lifetime event. To view the eclipse, you'll need something at a 12, 13 or 14.

Here's a test, put on the glasses and if you can see the room you're in you probably shouldn't use those glasses to look at the sun.

"Even the tiniest sliver, even 1 percent of the surface of the sun is so bright. you could potentially injure your eyes", the American Astronomical Society's Fienberg cautioned.

You watch the projected image, with no risk of sun damage.

You can also check out other options on the American Astronomical Society's list of reputable brands and retailers. "This video shows the time and what you'll see of the eclipse in various areas here in Utah", according to KSL-TV.

The business said the recall only applies to the Vision Source eclipse glasses sold last week.

But before you grab the first pair of "eclipse glasses" you find online, eye professionals are warning you to be careful of unapproved, or even discount/counterfeit glasses that might not provide any protection at all.

"Instead, Young said, search for NASA approved cardboard glasses, with an "ISO" logo".

Peru State College in Nebraska, which lies in the path of the eclipse, ordered 7,500 pairs for students but discovered the shipment from a Chinese distributor was defective and came with safety certificates for ordinary sunglasses. Homemade filters nearly certainly will not work.

Safe eclipse glasses should be stamped with a label indicating they meet the worldwide "ISO 12312-2" standard - although Fienberg said counterfeiters have also started to print that on fake glasses.

"While Utah won't be in the zone of totality for the upcoming solar eclipse, you'll still be able to see a partial solar eclipse".

Amazon has said that the glasses it sells directly all meet NASA guidelines, but it can not guarantee the same with all its third-party vendors.

Many libraries and eye doctor offices have been handing out officially approved glasses free of charge, but some of them report they are running out.

In Madison on Friday, the glasses were sold out at Kirkland's on the Far East Side and at Toys R Us on the Far West Side.

As a result, demand is soaring for safe glasses for viewing it. For anyone who welds as part of their profession or as a hobby, this could be a way to not have to buy anything new at all.

The group recommends only using a welding mask if you're certain of its "shade number", an indication of how dark the mask's tint is.
