    On April 8th, 2024, tens of millions of people across America will gather to witness a rare and awe-inspiring celestial event – a total solar eclipse. As the moon passes between the sun and the earth, day will turn to night for a few brief minutes. To prevent damage while viewing this dazzling phenomenon, many will don solar eclipse glasses to protect their eyesight. But are these special glasses really effective and safe?

    Are Solar Eclipse Glasses Safe for Your Eyes?

    Solar eclipse glasses are safe for eyes if properly certified. The American Astronomical Society recommends eclipse glasses that meet the ISO 12312-2 international safety standard, which ensures they filter out harmful ultraviolet and infrared radiation. Verify glasses are not damaged or expired. While regular sunglasses are not safe, homemade viewers can be created using cardboard and aluminum foil to indirectly view the eclipse. Always supervise children and never look directly at the partial eclipse, even with glasses.

    ISO-certified and NASA certified solar eclipse glasses

    The key is to only use eclipse glasses that meet accepted safety standards. These glasses are not regular sunglasses – they are specially designed to filter out 100% of harmful ultraviolet and infrared rays. Regular sunglasses will not provide adequate protection. Counterfeit eclipse glasses may look like they meet safety standards, but could actually lead to eye damage. When purchasing eclipse glasses, verify they are certified to meet the ISO 12312-2 international standard. You can check the manufacturer’s website for verification.

    Inspect your eclipse glasses to make sure they are not scratched or damaged before use. Don’t use eclipse glasses that are more than 3 years old or have expired – they can develop microscopic holes that allow radiation to pass through. Supervise children using eclipse glasses at all times. Even when wearing proper eye protection, never look directly at the sun during a partial eclipse, when the sun is still partly visible. The only time it is safe to view the eclipse directly is during the brief time of totality when the moon fully covers the sun.

    Indirect Viewing the Eclipse

    For an indirect and safe way to view the solar eclipse, you can create a simple pinhole camera by poking a small hole in cardboard or paper and aiming it at the sun. Using aluminum foil, you can also fashion a homemade viewer. But specialized eclipse glasses remain the best way to protect your vision and see this extraordinary astronomical event. With proper eye protection, you can experience the awe and wonder of the eclipse safely.

    So don’t miss out on the opportunity to witness this rare phenomenon. With certified eclipse glasses that meet accepted safety standards, you can gaze skyward and enjoy the eclipse without worrying about damage to your eyes. Just remember to buy from a reputable source, check for certification, and supervise children at all times.
