If you have not purchased your solar eclipse glasses yet, you might want to get on that. Supplies are selling out fast.

As you look for a pair, the thought might cross your mind, are these any good? How do I know if the solar glasses I'm about to buy are really the best view and the best eye protection at the same time?

Just because they are expensive does not mean that they are the best. Just because they are cheep does not mean that they are the worst. So how do you know? NASA has provided an explanation of details. 

First, look for glasses that are CE and ISO certified. Just because the seller's website says that they are, does not mean it's true. Go to the official list and find out if what you want to buy is on it.

On the low end of the price spectrum are the Rainbow Symphony, which will provide the best bang for your buck. They have a simple cardboard frame and are CE and ISO Certified for quality and safety. These are great if you need to buy a bundle for a group of people. Price: $11.95 a pair.

You can really go crazy and look cool with a pair of welder’s goggles. Just make sure they are made with Shade 14 welder’s glass. The goggles fully eliminate the harmful UV and IR light. Price: $19.95.

The Phillips Solar Eclipse Safety Glasses are a  bit more expensive at $29.80. What is very important is that, much like the welder's goggles, they provide protection on all sides, not just up front.

If you want the bottom of the barrel in price but good quality protection then visit our friends at DayWeather.com They have compiled a list of the cheapest of the cheap, but still effective protection.

Just putting on several pairs of glasses over glasses or other home made solutions will not work. Make sure you buy from a company that has been inspected and certified.
