How to Experience the Great American Solar Eclipse Without Damaging Your Vision

Slade & Baker Vision and the American Academy of Ophthalmology offer tips on how to safely view this once-in-a-lifetime event

HOUSTON, TEXAS– AUGUST 15, 2017 — On Aug. 21, millions of people in the U.S. will see day turn to night as a total solar eclipse passes over North America. The last time this happened from coast to coast was 1918. Temperatures will drop rapidly as the moon completely covers the sun. You will be able to see the spectacular colors and light of the sun’s atmosphere, a sight revealed to us only during a total solar eclipse.

While you cannot completely prepare yourself for the sight of a total solar eclipse, ophthalmologists — physicians who specialize in medical and surgical eye care — want you to be prepared with proper eye protection. Viewing even the smallest sliver of a crescent sun peeking out from behind the moon is enough to cause irreversible damage to your vision.

Russell N. Van Gelder, MD, Ph.D., a clinical spokesperson for the American Academy of Ophthalmology, has treated patients who have lost vision to the sun.

“The complete solar eclipse is a wonderful and memorable phenomenon that should be experienced by everyone in the eclipse path,” said Dr. Van Gelder. “It is essential, however, that viewing is done safely. Viewing the sun directly, even for brief periods, can cause permanent damage to the retina and result in blindness. I have patients who viewed the sun 40 years ago, who remain without central vision in their affected eyes.”

“It’s important to remember that even 100% UV protective sunglasses are not enough to protect from looking at the sun. Additionally, eclipses give our eyes sharp moon edges to focus on, which focuses the sunlight directly on the center of vision, where the damaging burn occurs,” said Bennett Walton, MD, of Slade & Baker Vision. “Couple that with the fact that the lower brightness of an eclipse is less uncomfortable, and you have the recipe for people to really cause some serious damage that may be permanent.”

Dr. Van Gelder explains that the lenses in your eyes act like a magnifying glass, one that is 5 times more powerful than a handheld magnifier. Think about how you can use that typical handheld magnifier to focus the sun to burn holes in paper. That’s what happens when you look at the sun without eye protection. You focus the sun’s light on the retina, burning holes in light-sensitive photoreceptor cells, causing blindness.

There is one exception to this rule. There is a brief phase during a total solar eclipse when it is safe to look directly at the sun. This phase is called totality, and it lasts about 2 minutes. It occurs when the moon entirely blocks the sun’s bright face. But as soon as the sun begins to reappear, put the solar filters back on. The path of totality for the Aug. 21, 2017, total solar eclipse is about 70 miles wide and stretches from Oregon to South Carolina. It passes through Idaho, Wyoming, Nebraska, Kansas, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina and South Carolina. Outside the path of totality, sky watchers will see a partial solar eclipse.

There are no exceptions to the rules for safely viewing a partial solar eclipse. To make sure people have the facts, the American Academy of Ophthalmology has teamed up with the American Astronomical Society to offer these five tips:

• Use specially designed solar eclipse glasses and viewers to block the sun’s harmful rays. Ordinary sunglasses, even dark ones, are not strong enough to protect your eyes. To date, only four manufacturers have certified that their eclipse glasses and handheld solar viewers meet international safety standards:

o Rainbow Symphony
o American Paper Optics
o Thousand Oaks Optical
o TSE 17

• Inspect your solar filter before the eclipse, and don’t use it if it’s scratched or damaged.
• Another option is to view the eclipse through #14 welder’s glass. That’s much darker than the shades arc welders typically wear.
• Use solar filters on camera lenses, binoculars, and telescopes.
• Do not use solar eclipse glasses to look through a camera, binoculars or a telescope. The sun can melt the filter and damage your eyes.
