What happens if you look at eclipse without glasses?

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.

Can you look at an eclipse without glasses?

It is never safe to look directly at the sun's rays – even if the sun is partly obscured. When watching a partial eclipse you must wear eclipse glasses at all times if you want to face the sun, or use an alternate indirect method.

What happens if you look at a solar eclipse without sunglasses?

Special eclipse glasses work by blocking out the sun's UV rays (as well as some of the purple light wavelengths we can usually see). But staring at the sun sans specs puts you at risk for ”solar retinopathy,” which is when those UV rays overwhelm the part of your eye that takes in light, called the retina.

Can you look at eclipse with bare eyes?

The only time that the Sun can be viewed safely with the naked eye is during a total eclipse, when the Moon completely covers the disk of the Sun. It is never safe to look at a partial or annular eclipse, or the partial phases of a total solar eclipse, without the proper equipment and techniques.

How can I safely view an eclipse?

Poke a small hole in one piece of card using a compass or a similar tool. Stand with your back to the Sun. Hold both cards up, with the one with the pinhole closer to the Sun. The light through the pinhole can be projected on to the other piece of card, allowing the eclipse to be viewed safely.

Why does an eclipse damage your eyes?

The sun's light is so intense that even a small sliver of exposed light is enough to cause irreversible damage. When a person looks directly at the sun, solar radiation hits the retinas, triggering a series of chemical reactions that can result in damage, or even destruction, of the photoreceptors in the eyes.
