Warby Parker offering free eclipse specs for April’s celestial event

By Trevor Mogg Published March 5, 2024

Quick to spot an opportunity, eyewear company Warby Parker has announced it will be handing out free eclipse glasses for safe viewing of April’s highly anticipated celestial event.

“An astronomical phenomenon is coming on April 8 — the last total solar eclipse visible from the contiguous United States until 2044 — and whether you’re getting a full view or a partial peek, we’re here to help you see it,” Warby Parker said in a message on its website, adding, “As avid supporters of sharp vision, we want to make sure you have everything you need to safely witness this celestial spectacle.”

You can pick up your free eclipse glasses from any of Warby Parker’s more than 250 stores across the U.S. (its website has a full list of store locations) from April 1. It’s offering up to two pairs per family while supplies last. We’re betting the offer will be popular, so do swing by as early as possible if you’re keen to grab a pair (or two).

Warby Parker says that if you miss out, it’ll hand you a free eclipse pinhole projector instead, which offers another way to safely view April’s solar eclipse. If you can’t make it to a store, then you can download the template for the DIY pinhole eclipse projector from this Warby Parker webpage.

The specs are made by American Paper Optics and are ISO-certified, meaning they’re safe to use for viewing the event.

The total solar eclipse on April 8 will see the narrow path of totality fall over Mexico (from Sinaloa to Coahuila), the U.S. (from Texas to Maine), and Canada (from Ontario to Newfoundland). A partial eclipse will be viewable from almost all of North America and even parts of Europe. This Digital Trends article offers more more detailed information on the location of the eclipse’s path of totality across the U.S.

Be sure to take special care when viewing next month’s solar eclipse, and only use specially-made viewing devices or spectacles to do so. If you can’t get hold of Warby Parker’s specs, NASA has some excellent information on how to enjoy the breathtaking spectacle without damaging your eyesight.

How to watch this week’s solar eclipse in person or online

This Tuesday, October 25, a partial solar eclipse will be visible in some parts of the world as the moon passes between the Earth and the sun. Around a quarter of the sun's face will be obscured behind the shadow of the moon in what will be the final eclipse of 2022.

Parker Solar Probe detects a natural radio signal coming from Venus

When flying past Venus in July 2020, Parker Solar Probe’s WISPR instrument, short for Wide-field Imager for Parker Solar Probe, detected a bright rim around the edge of the planet that may be nightglow — light emitted by oxygen atoms high in the atmosphere that recombine into molecules in the nightside. The prominent dark feature in the center of the image is Aphrodite Terra, the largest highland region on the Venusian surface. Bright streaks in WISPR, such as the ones seen here, are typically caused by a combination of charged particles — called cosmic rays — sunlight reflected by grains of space dust, and particles of material expelled from the spacecraft’s structures after impact with those dust grains. The number of streaks varies along the orbit or when the spacecraft is traveling at different speeds, and scientists are still in discussion about the specific origins of the streaks here. The dark spot appearing on the lower portion of Venus is an artifact from the WISPR instrument.

A NASA spacecraft intended to study the sun has been doing some bonus science, revealing new information about Venus as it passes by the planet. It's been a long time since a spacecraft has taken a direct measurement of the Venusian atmosphere -- according to NASA the last time was almost 30 years ago when the Pioneer Venus Orbiter peered into the atmosphere in 1992 -- and the study has revealed some fascinating facts about our planetary neighbor.

NASA has shared this gorgeous image of Venus, captured by the Parker Solar Probe on a flyby of the planet in July last year. The probe's main mission is to explore the sun up close and learn about its corona, but it also regularly passes Venus as it uses the planet's gravity to adjust its orbit. The researchers staffing the mission don't let these flybys go to waste, and use the probe's instruments to learn about Venus as well on their way by.
