As you prepare for the solar eclipse on Aug. 21, remember: Not all eclipse viewing glasses are created equal.

You will want to make sure that yours meet a specific worldwide standard known as ISO 12312-2 (ISO stands for International Standards Organization), which means they are safe for looking directly at the sun. You’ll find the ISO information printed on your glasses. It’s sometimes written as ISO 12312-2:2015.

Glasses are available for purchase online and throughout the Valley, at local stores like REI, Idaho Camera and others; and free through public libraries beginning Aug. 1 on a first-come, first-served basis. (See box to learn which libraries are participating and holding special events.)

REI is selling the “Celestron EclipSmart Solar Shades Sun and Eclipse Observing Kit” with four pairs of glasses and a booklet with a complete eclipse timetable and map ($9.95) as well as a deluxe version that includes a photo filter for your phone or camera as well as glasses for you ($26.95). A third pack ($9.95) offers two pairs of glasses and a magnification filter.

Sales have been brisk, said Teri Garvin, an assistant store supervisor.

“Customers are excited. It’s a once-in-a-lifetime opportunity,” she said.

Initially, REI’s Boise store hadn’t planned to sell eclipse packs until staffers campaigned to corporate headquarters.

“Seeing as we’re in the path of totality,” said Brad Oakey, sales manager.

It was a good call. Eclipse packs have been selling as fast as the store can stock them, he said. Packs are available now, and more are on their way. Call ahead for availability to be sure.

Idaho Camera has safety equipment for your eyes and your cameras. They range from simple glasses for $3 to magnifying safety binoculars ($11.95 for a 2x magnifier, $39.95 for 10x magnifier) to the Celestron Solar Kit that includes glasses, a telescope, a filter, tripod and backpack to carry it all for $119.95.

Online, eclipse glasses can be purchased at , Amazon and many other retailers.

Once you have the glasses…

Even if your glasses have the proper ISO, inspect them closely before you use them to make sure they’re not damaged or torn. Dark sunglasses or homemade solar filters are not safe alternatives for eclipse viewing.

Those are just a few bits of information from the American Academy of Ophthalmology that Katherine Lee, a pediatric ophthalmologist at St. Luke’s Children’s Ophthalmology in Boise, is working to share.

Children, said Lee, are particularly at risk of eye damage during an eclipse. The lenses in children’s eyes are clear and thus more vulnerable to light. In addition, young children might not be capable of understanding the risk of sun exposure to their eyes.

“Any kid who can’t understand or follow instructions for viewing should not be included (during the actual eclipse),” Lee said.

Looking directly at the sun without proper eye protection can damage the retina, a condition called solar retinopathy. Solar retinopathy doesn’t cause pain. Symptoms may not be immediate, but they can include a permanent loss of vision, loss of color perception and distorted vision.

During totality, when the entire sun is fully covered, it’s OK to sneak a peek, said Lee. But be careful: Eyes are vulnerable as soon as a sliver of sun appears. Also, the pupils will be dilated in the fading light from the eclipse so will be extra vulnerable when light returns.

Protect your camera, too:

Lenses can magnify the light from the sun and damage your equipment, so you need to protect the lenses of your cameras — including the camera on your phone — your telescopes and any other lens with a solar filter. Filters are available at several local camera and outdoors stores.

So remember: Don’t look through the viewfinder of an unfiltered camera, or telescope or binoculars when it’s pointed at or near the sun, even if you’re wearing protective glasses.
