With the solar eclipse happening Monday, some of the hustle and bustle in the busiest city in the country will come to a standstill as people look up to see the moon cross the sun.

“We have so many people excited about capturing, viewing this eclipse," said Frank Multari, a sales manager of a local B&H. “If you want to use a camera and take pictures of the eclipse, you’re going to have to have a filter, a solar filter."

New York Department of Mental Health and Hygiene reminded people to not look up at the eclipse without protective eyewear.

The moon will only block 90% of the sun. That means the sun’s rays will still peak through despite the darkness the eclipse creates.

Looking up can lead to serious eye damage.

“It’s going to look like you can kind of just look at the eclipse, but you can’t. It’s going to be dark out, so you might feel comfortable just looking at the sun,” Multari said.

The city health department cautions people against using old eclipse glasses. It said if the glasses are more than three years old, toss them out.

The department also said if driving, walking or cycling, don’t get distracted.

Officials said to use a handheld solar viewer or eclipse viewing glasses, not everyday sunglasses, and to also stop by the city library where they have eclipse viewing glasses while supplies last.

“Yes, this is exciting, but fingers crossed for clear skies," said B&H customer Sona Shah.

Clouds in the city may be the only thing to let people down.

Some, though, are getting out of town and heading upstate to be along the line of totality.

The next solar eclipse visible in the city will be 2079.
