There will be a total solar eclipse visible across many parts of the United States on April 8, 2024. NASA reports the upcoming eclipse will be visible between Texas and Maine.

If you’re planning to gaze upon this once-in-a-lifetime event, you’ll need special glasses to avoid permanent eye damage. Regular sunglasses, even those that are polarized and that offer 100% UV protection, are not suitable.

What you need to know about eclipse glasses before you buy

The American Astronomical Society issued important guidelines for choosing the best glasses (also known as eclipse viewers) to wear during the upcoming solar eclipse. Not using the proper eyewear could cause blindness or permanent eye damage.

Proper solar viewers block all but a minuscule fraction of the sun’s ultraviolet (UV) and infrared (IR) light, which is what makes them safe to use.

Here are some inexpensive solar eclipse viewer options you can order online. These viewers have been approved by the American Astronomical Society and adhere to the ISO 12312-2 standard, allowing you to view the eclipse safely. Just don’t wait to place your order, or they could arrive too late.

What to know about the coming total solar eclipse

A total solar eclipse will be happening in the U.S. on April 8, 2024. What time the eclipse will be visible will depend on your location. According to NASA, the solar eclipse will begin in Dallas, TX at 12:23 p.m. local time (CT). It will begin in Caribou, ME at 2:22 p.m. local time (ET).

You can view the path of the total solar eclipse in the map above. Only a narrow band of the U.S. will be able to view the total solar eclipse.

A partial eclipse (the moon will partially block the sun) will happen for approximately two-and-a-half hours. A total solar eclipse (the moon will completely block the sun) will happen for between two and four minutes. Again, these times depend on location. You can view a full eclipse timeline at the NASA website.

Total solar eclipses happen somewhere on Earth once every one to three years, but one that happens in the continental U.S. is rare. According to NASA, the next total solar eclipse visible from the contiguous United States will be in 2044.
