Our Story

We founded HALO eclipse spectacles in order to raise awareness about the 2017 North American total solar eclipse and to provide sustainable options for safe eclipse viewing. As avid adventurers, we had been eagerly awaiting the eclipse for years and felt that a proper celebration of this astronomical rarity should be accompanied by beautiful and Earth-friendly eyewear.

HALO spectacles are crafted from durable and renewable bamboo and hardwoods, and our eclipse certified lenses are tested and certified by an independent professional testing facility and meet the requirements of ISO 12312-2:2015 for safe solar viewing during the eclipse.

When you make a purchase of HALO spectacles, you are supporting a conscientious approach to sustainability and integrity in our business practices. As part of our commitment, we use a portion of our proceeds to donate new glasses to classrooms in South America and support school eclipse viewing trips. We’ll also provide packaging to ship your glasses directly to organizations that collect eyewear.


When I was initially researching lens manufacturers for HALO for the 2017 eclipse, the first supplier I found provided certification from an unaffiliated company in Canada. When I pressed for more details and didn't get satisfactory answers, I passed on them and found a different company to make my lenses. As it turned out, Amazon ended up pulling all of the initial company's affiliated eclipse products offline. My shipping agent explained that certain China-based manufacturers consider it an SEO strategy to claim they meet certifications, which is terrifying but the reality of the situation. (Amazon eventually sent emails to people that purchased from some of these sources and refunded these purchases.)

Several other eclipse lens manufacturers that we reached to out also couldn’t provide the required certification, but we eventually found a supplier with a valid certification for ISO 12312-2:2013 standards and who was willing to get HALO glasses specifically re-certified for the superseding ISO 12312-2:2015 standard. We arranged for testing and passed certification in an internationally recognized independent testing lab. 

Serendipitously, my husband is a physicist with a Ph.D. in photonics and we have access to a ton of optical equipment including a spectrometer. For our own peace of mind, we independently tested the transmission of the sample sunglasses and verified that they meet ISO specifications as indicated by the certification testing.

I encourage everyone to stay diligent and do your research on the companies you're buying from. There are safe options out there, HALO eclipse spectacles among them.

We have just a handful of months left before the next totality! It's going to be glorious and I can't wait.

Happy and safe eclipsing,
