* Infrared radiation: This radiation is what we feel as heat. During a solar eclipse, the sun's infrared radiation can damage the delicate cells in the retina, the light-sensitive lining at the back of your eye. This damage can cause blurred vision, a blind spot, or even permanent blindness.
* Ultraviolet radiation: This radiation is invisible to our eyes but can cause sunburn of the skin, and similarly, it can damage the retina. It is also a significant contributor to cataracts and other eye diseases in the long term.
Why is it dangerous even when the sun is partially obscured?
Even during a partial eclipse, the sun's rays are still incredibly powerful. Your pupils dilate to try and let in more light, making your eyes even more vulnerable to damage.
How to view an eclipse safely:
* Never look directly at the sun, even for a brief moment, without proper eye protection.
* Use certified solar eclipse glasses or viewers. These glasses have special filters that block out harmful radiation.
* Project the sun's image onto a piece of paper using a pinhole projector. This is a safe way to view the eclipse indirectly.
* Follow the guidance of reputable organizations like NASA and the American Astronomical Society. They provide detailed information about safe eclipse viewing practices.
Remember: Even during a total eclipse, it's unsafe to look directly at the sun without proper eye protection during the brief moments before and after totality.
It's important to prioritize eye safety during an eclipse, as the damage caused can be permanent.
