The countdown to the total solar eclipse on April 8th, 2024, is on, and Eclipse Glasses USA is here to ensure a secure viewing experience for this spectacular event. As the top supplier of solar eclipse glasses that meet the ISO 12312-2:2015 standard, we want to stress the significance of this standard as a marker of safety and effectiveness for our range and others in the market.

The ISO 12312-2:2015 standard, developed by the International Organization for Standardization, prescribes the specifications for the safe direct observation of the sun. This is particularly relevant for those looking forward to solar eclipses or sunspot observation and covers important safety considerations such as optical density, the transmittance of solar radiation, and the requirements for filters in eyewear designed for direct sun observation.

Our products at Eclipse Glasses USA are thoroughly tested to ensure they align with ISO 12312-2:2015 standards. This guarantees that our glasses not only mitigate the sun’s brightness to safe levels but also block out harmful ultraviolet (UV) and infrared (IR) rays, thus protecting your eyes from potential damage and ensuring a clear view of the eclipse.

As the April 8th total solar eclipse draws near, it’s critical for viewers to rely on ISO-certified eclipse glasses. The use of non-compliant eyewear can lead to severe eye conditions such as solar retinopathy, caused by inadequate shielding from the sun’s intense light and invisible radiation. Though not typically fatal, such conditions can result in permanent visual issues.

The eclipse glasses market is further complicated by various online retailers who inaccurately claim their products are ISO-compliant without meeting the necessary standards. In cases of doubt, consumers should request the vendor’s ISO testing documentation, which should be readily available from a reputable, accredited US lab.

Furthermore, these documents should offer detailed testing results for luminosity, UV, and IR, showcasing exact performance metrics. Caution is advised with results that simply state “pass” or “fail” without indicating the precise performance within the safe range.

Reviewing the American Astronomical Society’s (AAS) list of reputable eclipse glasses vendors is also recommended. Vendors on the AAS list have satisfied the organization’s strict criteria for approval. It is advisable not to purchase glasses from vendors not on this list.

Eclipse Glasses USA is honored to provide products that meet the strictest safety criteria. We encourage schools, astronomy clubs, and the broader community to prepare for this rare astronomical event by securing their ISO 12312-2:2015 compliant solar eclipse glasses well in advance.
