  • What are the symptoms of eye damage from viewing a solar eclipse?

The solar eclipse wowed viewers across the United States today (Aug. 21) as it passed from the West to the East coast.

"The sun is a big ball of fire putting out radiation", said Dr. Mark Blecher, with Wills Eye Hospital.

Tomososki told Today.com that he suffered permanent eye damage when he looked up at the partial solar eclipse over OR in 1962.

But if you're still tempted to peek - if you're, say, the type who asks, "But why shouldn't I stick this fork into this plug socket?" - it may help to hear from an eye specialist who has studied those rare people who do gaze right into the sun - typically because of a psychiatric condition, or as part of a religious experience - and suffer what's called a "solar burn" to their eyes. "This exposure to the light can cause damage or even destroy cells in the retina (the back of the eye) that transmit what you see to the brain".

Recovery depends on the extent of exposure and the severity of damage. Not only can humans not see infrared rays coming from the sun, but we also have no pain receptors in our retinas, leaving us susceptible to permanent damage without even knowing it until its far too late.

Symptoms of solar retinopathy can occur within hours of looking at the sun but can take as long as 12 hours to appear. Hopefully the effects are minimal and, for the next eclipse, you buy a pair of protective eclipse glasses or stay inside.

Wills Eye Hospital had a last-minute giveaway of solar glasses on Monday. Looking directly at the sun can cause permanent damage to your eyes.

The only safe way to view a partially eclipsed sun is through special-purpose solar filters, such as "eclipse glasses" or viewers that meet global standard ISO 12312-2 for safe viewing. If your eyes hurt, see an eye doctor immediately. Visit a local eye care professional for a comprehensive exam if you or a family member experience discomfort or vision problems following the eclipse.

Has anyone ever really had their eyes damaged by an eclipse? One Portland man, now 70, said he watched an eclipse for about 20 seconds with one eye covered on a high school baseball field in 1963. "And that's what can happen to your retina by staring at the sun for even a few seconds".
