ISO 12312-2 Eclipse Glasses for the 2027 Solar Eclipse

Certified Eclipse Glasses for 2 August 2027

The total solar eclipse of 2 August 2027 will be one of the most remarkable astronomical events of the decade. Millions of people across Europe, North Africa and the Middle East are expected to watch the eclipse.

Looking directly at the Sun requires appropriate eye protection. Eclipse Glasses Europe supplies eclipse glasses compliant with ISO 12312-2, the international safety standard applicable to filters for direct observation of the Sun.

Our eclipse glasses are available in bulk quantities for hotels, resorts, retailers, municipalities, tourism organisations, events and other businesses preparing for the 2027 solar eclipse.

What is ISO 12312-2?

ISO 12312-2 is the international standard for filters designed for direct observation of the Sun. It sets requirements for solar viewers, including eclipse glasses, to ensure that harmful levels of solar radiation are sufficiently reduced when the product is used correctly.

The standard covers important aspects such as the amount of visible light, ultraviolet (UV) radiation and infrared (IR) radiation that may pass through the filter. It also includes requirements relating to the quality and uniformity of the filter material and the information supplied with the product.

This is important because ordinary sunglasses are not designed for direct solar observation. Even very dark sunglasses do not provide the same type of protection as solar viewers that comply with ISO 12312-2.

For organisations purchasing eclipse glasses for guests, visitors or customers, checking compliance with ISO 12312-2 is therefore an important part of selecting suitable solar viewing products.

Eclipse Glasses Europe supplies eclipse glasses that comply with ISO 12312-2 and are intended for safe direct observation of the Sun when used according to the supplied instructions.

Why Certified Eclipse Glasses Matter in 2027

During a partial solar eclipse, part of the Sun remains visible. Looking directly at it without appropriate solar viewing protection can cause serious eye injury.

This is particularly important during the 2 August 2027 eclipse, when large numbers of visitors are expected to travel to destinations within and around the path of totality.

Appropriate eclipse glasses should be worn whenever any part of the bright solar surface is directly visible.

For locations experiencing totality, eclipse glasses may only be removed during the brief period when the Sun is completely covered by the Moon. They must be put back on before the bright Sun begins to reappear.
