A Rare Total Solar Eclipse.

A total solar eclipse will cross the United States on April 8, 2024, passing over Texas and traveling through Oklahoma, Arkansas, Missouri, Illinois, Kentucky, Indiana, Ohio, Pennsylvania, New York, Vermont, New Hampshire, and Maine. Weather permitting, it will be a partial eclipse for us in Colorado.

It will be the last total solar eclipse visible from the contiguous United States until 2044.

Let’s get those peepers prepped for viewing.

Except during the brief total phase of a total solar eclipse, when the Moon completely blocks the Sun’s bright face, it’s not safe to look directly at the Sun without specialized eye protection for solar viewing.

Protect your eyes during the eclipse.

Use approved solar eclipse viewers. The only safe way to view a partially eclipsed sun is through special-purpose solar filters, such as “eclipse glasses” or viewers that meet international standard ISO 12312-2 for safe viewing.

Keep in mind, regular sunglasses are NOT eclipse glasses – regular sunglasses, no matter how dark, are not safe for viewing the sun.

Sunglasses, smoked glass, unfiltered telescopes or magnifiers, and polarizing filters are unsafe. Inspect your eclipse glasses or handheld viewer before use – discard the device if torn, scratched, or otherwise damaged.

The pros use the following technique:

Stand still and cover your eyes with your eclipse glasses or solar viewer before looking up. After viewing, turn away and remove your glasses or viewer—do not remove them while looking at the sun. If you usually wear eyeglasses, wear your eclipse glasses over them or hold your handheld viewer in front of them.

Totality is awesome.

Only within the path of totality—and once the moon completely blocks the sun—can eclipse glasses safely be removed to view totality with the naked eye. However, once the sun begins reappearing, eclipse glasses and handheld viewers must be replaced to protect your vision. In Colorado, your eclipse viewers should be worn the entire time. 

After the eclipse:

If you should experience discomfort or vision problems following the eclipse, contact Van’s Eyecare immediately to schedule a comprehensive eye exam. Some common symptoms include:

      • Loss of central vision, or solar retinopathy,
      • Distorted vision
      • Altered color vision.

If you have any of these symptoms, call us immediately.
