Eclipse Glasses Safety Info

Safety Standards for Eclipse Glasses

Eclipse glasses are necessary for viewing a partial or total solar eclipse. These glasses are different than regular sunglasses or tinted glasses. Genuine eclipse glasses must meet the ISO 12312-2 international safety standard, which determines the specific criteria for safe eclipse viewing.

Eclipse glasses should have a special solar filter to block the sun's harmful UV and infrared rays, allowing only a limited amount of visible light to reach the eyes. ISO 12312-2 standard lays the eclipse glasses guidelines that provide sufficient protection from harmful sun exposure while viewing the eclipse.

Risks of Wearing Unsafe Glasses

During a solar eclipse, it's never safe to view the sun without wearing proper eclipse glasses. You can't use a camera lens, a telescope or binoculars without the special solar filter because the concentrated solar rays can cause serious eye injuries. Always look through eclipse glasses, which are a thousand times darker than ordinary glasses. The specialized glasses must comply with the ISO 12312-2 international standard; check them for any damages before using them. Buy them only from trusted vendors to avoid problems.

Tips for Safe Solar Eclipse Viewing

Are you planning to watch the solar eclipse? Prioritize safety with the tips below:

Wear eclipse glasses during the partial eclipse phase; remove them only during totality.
Only use sunglasses or wear no eye protection when the moon completely blocks the sun. You can only safely look up when you can no longer see any part of the sun.
Always wear eclipse glasses before or after the totality. Avoid eye injury by immediately putting on the eclipse glasses when you see a bit of sun reappearing.
To prevent skin damage when watching the eclipse, wear sunscreen and protective clothing or a hat.

How to Verify the Authenticity of Eclipse Glasses

Several counterfeit eclipse glasses are available, but they don’t provide enough protection for your eyes as genuine eclipse glasses. It’s crucial to purchase eclipse glasses only through reputable vendors you trust. Search for the manufacturer’s details on the glasses and verify their credibility online.

Look for the ISO certification label on the glasses to confirm that the glasses are safe for solar viewing. Check the glasses for any scratches, defects or signs of damage. Eclipse glasses verification is crucial to protect your eyes from significant damage. To help, we've created a 4 step verification method called "The Core 4".
