Only buy eclipse glasses from trusted retailers
A solar eclipse is one of nature’s most spectacular events, but it can also be dangerous if viewed without proper eye protection. That’s why choosing where you buy your eclipse glasses is just as important as remembering to wear them.
The risks of unsafe eclipse glasses
Looking directly at the Sun without appropriate protection can cause serious and permanent eye damage. During a solar eclipse, the reduced brightness can make it feel safer to look at the Sun, but harmful solar radiation is still present and can damage the retina without causing immediate pain.
Unfortunately, major eclipses often attract counterfeit and substandard eclipse glasses. These products may look genuine but fail to provide adequate protection, putting users at risk.
Understanding the ISO 12312-2 Standard
Safe eclipse glasses should comply with the international safety standard ISO 12312-2. This standard specifies the requirements for filters intended for direct observation of the Sun.
Glasses that meet this standard reduce sunlight to safe levels and block harmful ultraviolet and infrared radiation. Reputable manufacturers test their products to ensure they meet these strict requirements before they reach consumers.
Why trusted retailers matter
Buying from a trusted retailer provides an additional layer of confidence. Established retailers carefully source their products from recognised manufacturers and can provide information about the origin and certification of the glasses they sell.
Trusted suppliers are also more likely to stay informed about safety guidance from astronomy organisations and consumer protection agencies. They understand the importance of quality control and have a reputation to protect.
Most importantly, trusted retailers can trace their products back to the original manufacturer. This traceability helps ensure that the eclipse glasses you receive are the same products that have been tested and certified.
Be careful with online marketplaces
We generally do not recommend purchasing eclipse glasses through online marketplaces such as eBay. While some legitimate products may be available, it can be difficult for consumers to verify the origin, certification, and authenticity of products sold by individual marketplace sellers.
Consumers should also exercise caution when buying through large online marketplaces such as Amazon. Although many reputable manufacturers sell through Amazon, third-party sellers can also list eclipse glasses. In some cases, products from different suppliers may pass through the same fulfilment and distribution systems, making it harder to verify exactly which manufacturer’s product will ultimately be delivered.
When eye safety is involved, it is always preferable to buy directly from a trusted astronomy retailer, science supplier, museum, observatory, or an authorised distributor that can clearly identify the manufacturer and certification of the eclipse glasses being sold.
How to Buy Safely
When purchasing eclipse glasses:
- Check that the glasses are labelled as compliant with ISO 12312-2
- Buy from established retailers with a proven track record in astronomy, science education, or eclipse viewing
- Ensure the retailer can identify the manufacturer of the glasses they are selling
- Avoid suspiciously cheap products from unknown sellers
- Inspect glasses before use and do not use them if they are scratched, damaged, or torn
- Follow the manufacturer’s instructions carefully
Enjoy the eclipse with confidence
A solar eclipse is an unforgettable experience, but only when viewed safely. By purchasing eclipse glasses from trusted retailers and ensuring they meet the ISO 12312-2 safety standard, you can enjoy the event knowing your eyes are properly protected.
When it comes to eclipse viewing, safety should never be left to chance. A trusted supplier provides not only certified eclipse glasses, but also the confidence that the product protecting your eyesight is exactly what it claims to be.
