Will you go blind if you look at a solar eclipse?
Exposing your eyes to the sun without proper eye protection during a solar eclipse can cause “eclipse blindness” or retinal burns, also known as solar retinopathy. 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.
How long does it take for a solar eclipse to damage your eyes?
The biggest risk you expose yourself to if you stare at the sun during a solar eclipse is retinopathy. This is when solar radiation damages the retinas. The effects of retinopathy become noticeable after 4 to 6 hours, but they may take as long as 12 hours to appear for some people.
How long can you stare at a solar eclipse?

What do blind people see?
A person with total blindness won’t be able to see anything. But a person with low vision may be able to see not only light, but colors and shapes too. However, they may have trouble reading street signs, recognizing faces, or matching colors to each other. If you have low vision, your vision may be unclear or hazy.
Why can’t we look at a solar eclipse?
Because of its intensity, viewing even a small slice of the sun can be dangerous. The lens of the eye focuses and concentrates sunlight on the retina, scorching it and leading to solar retinopathy; because the retina has no pain receptors, you won’t be aware of the damage until it’s too late.
