After months of preparation, New Hampshire, along with many other parts of the country, experienced the solar eclipse. But now, what can you do with the eclipse glasses?

Save them 

According to NASA, eclipse glasses with valid certification can typically be saved for up to three years, but check the manufacturer’s notes. The next partial solar eclipses will be visible in March 2025, August 2026, and January 2029.

Recycle them

Instead of throwing them away, recycle the eclipse glasses. Remove the lenses from the glasses and recycle the cardboard frames. The solar filters used cannot be recycled.

Donate them

Only eclipse glasses with the ISO logo can be donated. Other types will not be accepted by many collection programs due to quality issues. Make sure the lenses are free of any rips, punctures, or holes that could allow radiation to penetrate the eyes.

Astronomers Without Borders is one organization that collects eclipse glasses and distributes them to people in Asia, Africa, North and South America who do not have glasses to view solar eclipses safely.
