They should be from a reputable manufacturer and meet this international safety standard. Check for the ISO 12312-2 certification label on the glasses before use. Damaged or scratched glasses should never be used. Discard any glasses that are older than three years or show any signs of wear and tear.
Indirect Viewing Methods
Aside from certified solar viewers, several indirect methods allow safe eclipse observation. One popular technique involves creating a pinhole projector. This simple device projects an image of the sun onto a surface, allowing you to view the eclipse indirectly without looking directly at the sun. A small hole, punched in a piece of cardboard, acts as a lens, projecting the sun’s image onto another surface, such as a piece of white paper or a wall, held several feet away. Adjust the distance between the pinhole and the screen to achieve a sharp image.
Another safe method is using a projection technique with binoculars or a telescope. Never point these directly at the sun without a proper solar filter. Instead, project the sun’s image onto a white surface using the optics. This will create a magnified image of the eclipse that is safe to observe. Remember to always use caution and never look through the device directly at the sun, even during projection. Carefully position the telescope or binoculars to project the image onto a screen, adjusting the focus as needed.
