Here's why:
* The sun's harmful rays are still present: Even during a total solar eclipse, when the moon completely covers the sun, the sun's corona (the outer atmosphere) emits intense ultraviolet and infrared radiation.
* The retina is vulnerable: These rays can damage the retina, the light-sensitive layer at the back of the eye. Unlike other parts of the body, the retina doesn't feel pain when it's being damaged.
* Damage can be irreversible: The damage caused by looking at the sun during an eclipse can be gradual and you may not notice it immediately. However, it can lead to permanent vision loss, including central vision loss, which affects your ability to see straight ahead.
It is never safe to look directly at the sun, even for a short time, without proper eye protection.
Here's how to view a solar eclipse safely:
* Use certified solar eclipse glasses or handheld solar viewers: These are specially designed to filter out harmful radiation.
* Project the sun's image: You can use a pinhole projector or a telescope to project the sun's image onto a white surface.
* Attend a viewing event: Many organizations host safe viewing events with certified equipment and knowledgeable staff.
Never use regular sunglasses, smoked glass, or photographic film to look at the sun. These materials do not provide adequate protection.
