The Solar Eclipse Burned an Image of Itself Onto a Woman’s Retina
Like so many others, 26-year-old Nia Payne wanted to view August’s historic solar eclipse but didn’t have a pair of protective glasses.

Are they rods and cones?
They look like they have been depressed.
A three d image would be interesting to look at.

“Looked like eclipse glasses” would have to be binoculars, wouldn’t they?
Suppose they were 8×32 glasses. Then she would be getting 8 times the amount of sunlight as the naked eye. Or would it be 8^2 = 64 times as much light? 64 times as much I think.
Eclipse glasses look like ordinary glasses dont they?

Certainly would cause more damage.
This has been known for a loooong time. What they are really saying is…we’ve got a you bewt fabulous machine (that might go “ping”) and now we can see the bit of damaged retina. Perhaps previously they have only half believed the patient who described a crescent scotoma. But I doubt it.
My specialist has a couple of different eye imaging machines. The 3D laser can one produces amazing images.

Eclipse glasses look like sunglasses, but are much darker. Like arc welding glass.

They don’t look like binoculars.
Some information:
“There are two main mechanisms of retinal injury from solar radiation. Thermal burn is caused by looking at the sun through a telescope or through other optical aids, which can cause a temperature rise of10-25°C in the retina. But the most common form of solar retinopathy is caused by looking at the sun without eye protection. A retinal temperature rise of as little as 4°C can trigger photochemical injury to the retinal receptor cells. The condition can occur without pain and without being immediately apparent. No treatment has been shown to be effective for solar retinopathy. In some cases the retinal changes seem to be reversible, but in others there is permanent loss of the photoreceptors. In a study after an eclipse in Turkey in 1976, around 10%of those with damage had permanent visual loss to the extent that they were not able to read a car number plate at 25 yards (23 metres) with the affected eye or eyes.”
