Just make sure to not look up to protect your eyes from sun damage. (seriously not kidding)

Also do not use your cell phone to look from there, it too can cause eye damage.

Aug. 21 solar eclipse

The eclipse will fully obscure skies in parts of the United States while partially blocking the sun in Canada. Such partial overlaps of the moon and sun are all the more dangerous because the sun remains exposed to people viewing the eclipse.

“Because it’s not completely blocked, we’re never safe from the damaging rays of the sun,” says ophthalmologist Dr. Cynthia Qian.

Damage from looking directly at the sun can be incurred in just a few seconds. 

“The problem with the back of the eye is that there’s no pain sensors, so all this damage can occur without you even knowing about it until it’s far too late,” says Ralph Chou, a University of Waterloo optometry professor and president of the Royal Astronomical Society of Canada.

Commercially available sunglasses offer insufficient protection when looking directly at the sun, Qian says.

Sunglasses allow thousands of times more sunlight than is safe to reach your eyes. NASA says special solar eclipse glasses should be marked with the “ISO 12312-2” international safety standard on the label. 

Qian adds that looking directly at the sun through the aperture of a phone, camera or telescope is also unsafe.

“Those systems are like when you use a magnifying glass and you can burn a page of paper.” 

Specialized adapted filters are available for some optical devices. Wearing eclipse glasses while looking through a camera or telescope aperture is not a suitable alternative; those devices can burn or melt the sunglasses, thereby affecting their effectiveness.

The American Astronomical Society publishes a list of reputable sellers of ISO 12312-2 eclipse glasses. Qian says Montrealers who do not have eclipse glasses but want to directly take in the eclipse should attend viewing events organized by the Montreal planetarium and McGill University, where suitable protections will be made available. 

As the eclipse, special glasses that actually offer the requisite protections are becoming increasingly difficult to obtain. 

This week, Amazon pulled potentially shady glasses from its site and issued refunds to customers who had already purchased them. In an email to buyers, the company said it could not get confirmation from the supplier that the glasses came from a recommended manufacturer.

“We recommend that you DO NOT use this product to view the sun or the eclipse,” the email said
