A total solar Eclipse will sweep across the continent, turning 21 August, the day into night.

That’s why NASA has published guidelines for the safe observation of the Eclipse.

NASA says that anyone who wants to observe the Eclipse, don’t have to do this directly. Instead, you can use the “shaded glasses” or to observe the Eclipse using the indirect method.

Eclipse glasses (“shaded glasses”) is the only safe way to look directly at the sun when the Eclipse happens. Nasa says that their eyeglasses are available for purchase in most places.

But you want to make sure that the glasses are in order, they should not be scratched, damaged lenses, and they should not be more than three years. Glasses must include the name and address of the manufacturer, who can check in online, and ISO.
