They block harmful ultraviolet (UV), visible, and infrared (IR) light, protecting your eyes from damage. The American Astronomical Society (AAS) emphasizes the importance of using certified glasses to ensure safety during solar observations.

The Risks of Counterfeit Glasses

The AAS warns about the risks associated with counterfeit solar glasses. Many counterfeit products are made in factories, particularly in China, and may not meet safety standards. For instance, glasses printed with the name of a reputable manufacturer but lacking proper certification can pose serious risks. The AAS has identified counterfeit glasses that appear safe but do not provide adequate protection.

Identifying Safe Solar Glasses

To ensure your solar glasses are safe, follow these guidelines:

Check for Certification: Look for ISO 12312-2 compliance on the packaging.
Perform the Indoor Test: Put the glasses on indoors; you should see nothing except very bright lights.
Outdoor Test: Take them outside on a sunny day; you should only see the sun’s reflection faintly.
Look at the Sun: If you can see anything other than a sharp-edged, round disk, the glasses are not safe.

Where to Buy Safe Solar Glasses

When purchasing solar eclipse glasses, it’s crucial to buy from reputable vendors. Websites like cbsaustin.com and jaxyopticalinstruments.com offer certified products. Additionally, bookishbunnyglasses.com provides clearance on surplus glasses that meet safety standards.

The Importance of Quality Assurance

Quality assurance is vital in the manufacturing of solar glasses. For example, Chautauqua County purchased glasses from Shenzhen POCE Technology Co. LTD, ensuring they met stringent safety measures.
