Solar Eclipses and Eye Safety
Eye safety should always be the number one priority when viewing a solar eclipse. Looking directly at the sun during a solar eclipse is unsafe and can cause temporary or even permanent damage to your eyes. Before viewing this natural phenomenon, learn more about proper eye safety to keep your eyes healthy.
Total Solar Eclipse: April 8, 2024
It will be the last total solar eclipse visible from the contiguous United States until 2044! So, let’s get those peepers prepped for viewing.
Tips for viewing a total solar eclipse:
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.
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. Sunglasses, smoked glass, unfiltered telescopes or magnifiers, and polarizing filters are unsafe. Inspect your eclipse glasses or handheld viewer before use – if torn, scratched, or otherwise damaged, discard the device.
Technique of the pros.
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 normally wear eyeglasses, wear your eclipse glasses over them, or hold your handheld viewer in front of them.
Totality awesome.
Only within the path of totality—and once the moon completely blocks the sun—can eclipse viewers safely be removed to view totality. Once the sun begins reappearing, however, viewers must be replaced.
Keep in mind! Eclipse glasses are NOT regular sunglasses – regular sunglasses, no matter how dark, are not safe for viewing the sun.
Symptoms from Incorrect Viewing:
It can take a few hours to a few days after viewing the solar eclipse to realize the damage that has occurred. If you experience discomfort or vision problems following the eclipse, visit your local doctor of optometry for an in-person, comprehensive eye exam. Some common symptoms include:
Loss of central vision,
Distorted vision, and
Altered color vision.
All symptoms should be treated as urgent until viewed by a doctor of optometry. If you suspect an eye or vision problem, don’t hesitate to visit a doctor of optometry – this is the best way to combat potentially severe complications, including vision loss.
