Solar Eclipse Safety: Protect Your Eyes
Indirect Viewing: A Safer Way
Observe the eclipse through indirect methods if possible. One way is to create a pinhole projector. Punch a small hole in a piece of paper and hold it up against the sun. The light will project an image of the eclipse onto the ground or a nearby surface.
Direct Viewing: Only in Totality
Direct viewing of the eclipse is safe only during totality, when the Moon completely blocks the Sun. Otherwise, serious eye damage can occur. If you plan on direct viewing, ensure you have certified eclipse glasses that meet the ISO 12312-2 international standard.
When To Wear Eclipse Glasses
- Before totality
- During partial phases
- After totality, until the Sun is completely hidden
Other Safe Viewing Methods
Besides certified eclipse glasses, other safe ways to observe the eclipse include:
- Tree leaves: Watch the sunlight filter through the leaves of a tree to create a dappled effect.
- Modified cereal box: Cover a cereal box with aluminum foil and poke a small hole in it. Point the hole towards the sun.
- Kitchen colander: Place a kitchen colander in front of a piece of paper or cardboard. The holes will project an image of the eclipse.
Caution: Avoid Harmful Methods
Never look directly at the sun without proper protection. Also, avoid using unfiltered cameras, binoculars, or telescopes, as they can harm your eyes.
