Solar Eclipse Safety

Our office wants you and your family to know about solar eclipse viewing safety.

On August 21, a total solar eclipse will touch the U.S. mainland for the first time since 1979, following a path that crosses the country from Salem, Oregon to Charleston, South Carolina. Tens of millions of people who live within a 70-mile radius of its cross-country track will witness the eclipse in totality (the sun completely blocked by the moon) while millions of others outside of it will enjoy a partial eclipse. The American Optometric Association (AOA), America’s family eye doctors, is urging Americans to view the eclipse with proper eye protection to avoid any temporary or permanent eye damage from the sun.

  • To ensure spectators won’t miss the remarkable sight, the AOA is sharing a few tips for safe viewing:
    Get centered and enjoy the view. Within the path of totality, you can safely witness the two or more minutes when the moon completely covers the sun with the naked eye. Otherwise, your eyes should always be protected by verified viewing tools. Never look directly at the sun without eye protection, even briefly. Visit eclipse.aas.org to access eclipse duration charts.
  • Know your duration. Outside of the path of totality, always use solar filters. Our eye doctor team wants to reinforce that the only safe way to look directly at the uneclipsed or partially eclipsed sun is through special-purpose solar filters or other ISO-certified filters, such as “eclipse glasses” or handheld solar viewers. The AOA encourages ordering solar eclipse glasses in advance and recommends referring to the American Astronomical Society’s (AAS) site for a list of manufacturers.

The only safe way to look directly at the uneclipsed or partially eclipsed Sun is through special-purpose solar filters, such as “eclipse glasses” (example shown at left) or handheld solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the Sun; they transmit thousands of times too much sunlight. See the Amercian Astronomical Society’s list of Reputable Vendors of Solar Filters & Viewers for a list of manufacturers and authorized dealers of eclipse glasses and handheld solar viewers verified to be compliant with the ISO 12312-2 international safety standard for such products.

  • Be aware of harmful solar exposure. If you stare at the sun without protection, you may experience damage to your retina (the tissue at the back of your eye) called “solar retinopathy.” This damage can occur without any sensation of pain, since the retina does not have pain receptors. The injury can be temporary or permanent. Visit your local doctor of optometry immediately if an accident occurs.
  • Check in with our doctors for information about safely viewing the eclipse. If you experience any problems with your eyes or vision after the eclipse, our office will be able to provide you with the medical care you need.
