What happens if you look at the sun for a few seconds?

These free radicals start to oxidize the surrounding tissues. They ultimately destroy the rod and cone photoreceptors in the retina. The oxidative damage is referred to as solar or photic retinopathy. Damage can occur in as little as a few seconds of staring directly at the sun.

How long do you have to look at the sun to go blind?

While recovery does occur for some people, it is possible to experience permanent visual acuity deficits. Permanent retinal damage can occur when someone looks at the sun for 100 seconds or less. This is under two minutes.

What happens if you stare at the sun for 10 seconds?

When you stare directly at the sun—or other types of bright light such as a welding torch—ultraviolet light floods your retina, literally burning the exposed tissue. Short-term damage can include sunburn of the cornea—known as solar keratitis.

What if you accidentally look at the sun?

The eye works like a camera, and the retina is like the film of your eye. So looking at the sun too long is almost like burning a hole in the center of your film, or retina. We don't have pain fibers there so you won't have discomfort or feel pain, but you might see a fuzzed out, dark spot.

Can retina damage be repaired?

Laser surgery can repair a retinal tear or hole. Your surgeon uses a laser to heat small pinpoints on the retina. This creates scarring that usually binds (welds) the retina to the underlying tissue. Immediate laser treatment of a new retinal tear can decrease the chance of it causing a retinal detachment.

What happens if you stare at the moon?
