Some eclipse glasses reportedly sold through Amazon have been recalled because they might not meet safety standards, according to the Illinois Department of Public Health.

The recalled glasses were sold as "Biniki Solar Eclipse Glasses AAS Approved 2024 — CE & ISO Certified Safe Shades for Direct Sun Viewing (6 Packs)." In addition to online sales, they were available at several stores in southern Illinois.

The recalled glasses were labeled as “EN ISO 12312-1:2022,” according to the health department. Proper eclipse glasses should have the manufacturer’s name and address clearly labeled, along with the ISO logo and the code “IS 12312-2” printed on the inside.

“People in possession of the recalled glasses should not use them to view the eclipse,” the public health department said in a statement. “Using inadequate eye protection could lead to serious eye damage.”

For wildlife, the sudden darkness of a total solar eclipse comes as a surprise. Birds might squawk to sound an alarm. Crickets start to chirp and owls hoot as if it’s nighttime.

We’re at a nature preserve near Little Rock to witness how wildlife responds to the total eclipse.

People who are visually impaired can still participate in eclipse festivities in Cleveland, thanks to a "LightSound" device that converts light from the sun into noise.

“So you hear the tone — brighter light is a higher pitch tone — and as the shadow passes over, it’s going to get lower and lower and lower until it’s just a series of clicks when it’s perfectly dark,” said Lindsay Deering, an information and education administrator at the Ohio Department of Natural Resources.

From Mexico to Maine, people have already begun to snag choice viewing spots, hoping to catch a view of the solar eclipse.

The Texas Eclipse Festival in Burnet has been canceled because of expected severe weather today through Wednesday, including the possibility of thunderstorms, hail, high winds and tornadoes.

“Your safety is our top priority. With the support and coordination of Burnet County officials, local safety agencies, and The National Weather Service, we’ve agreed to end the festival today in a calm orderly manner,” event organizers said in a post on the festival’s website.

Organizers said people can stay for the solar eclipse as long as they are prepared to depart after totality.

“This guidance may change based on weather,” officials said.

Newton Chu traveled more than 4,000 miles to witness today's total solar eclipse.

Journeying from Hilo, Hawaii, to Indianapolis, it will be Chu's third time experiencing totality. He saw his first total solar eclipse in 1991 from the summit of Mauna Kea in Hawaii, at an altitude of 13,500 feet. In 2017, Chu traveled to Sun Valley, Idaho, and witnessed totality atop one of the local mountains.

This time around, Chu said he's hoping to do something a little different.

“My goal is to see some planets this time, which I’ve never seen before in the daytime,” he said, adding that he'll be looking out for Saturn, Venus and even a rare comet that could be visible near Jupiter.

But ultimately, he wants to simply enjoy the experience of his third total solar eclipse. “Hopefully I’ll try to stay in the moment,” he said.

Chu said traveling to see eclipses has given him a good excuse to experience celestial events in the great outdoors while surrounded by friends and family.

“It’s really something quite special,” he said.

DALLAS — It’s pretty cloudy here, but it’s still early! And you never know what’s going to happen with the weather in Texas.That said, there is some expectation from forecasters that there could be some breaks in the clouds before storms roll in.

Eclipse mania is in full effect, but what exactly is taking place in the sky? NBC News’ Angie Lassman uses augmented reality technology to give a visual representation of what happens during a total solar eclipse.

BLOOMINGTON, Ind. — William Shatner, the oldest person to ever visit space, will be on stage narrating the moments leading to totality at Indiana University this afternoon.

Sitting down with NBC News, he expressed the magical feeling an eclipse will will provide: "It’s huge when you think about it. Celestial bodies are placing themselves between other celestial bodies."

But in combination with his fascination and curiosity about space, he advised humans “need to do both” when it comes to tackling climate change on Earth and exploring space around our home planet.

"You have to have a focus on the most important part, which is staying alive. I mean, what’s the point of going into space, if you can’t come back, or you were overcome by the fumes?" he said. "No, we’re in a dire situation. We’ve got to clean up the environment and add our curiosity and our ambition to see what’s out there."
