    Top 5 ways to help your patients safely view the solar eclipse


    4. Pinhole camera (indirect method)

    Creating a pinhole camera can be accomplished with a few simple supplies you found at home, office, or school.

    “The eclipse can be safely viewed indirectly with the pinhole method,” says Dr. Haynes. “With this method, you do not directly look at the sun but instead view a projected image of it created by a pinhole, making it a safe method.”

    NASA provides instructions on how to create a pinhole camera with:

    • Two pieces of white card stock

    • Aluminum foil

    • Tape

    • Pin or paper clip

    “This is a popular grade-school project to avoid any possibility of direct viewing among youngsters,” says Dr. Semes. “The pinhole focuses the eclipse image onto a screen, obviating the need to even be tempted to look at the eclipse directly.”
