About the Glasses

The Space Science Institute/STAR Net Library Network (STAR Net) is a hands-on learning network for libraries and their communities across the country. They supply free solar eclipse viewing glasses to libraries across the US while supplies last.

Public Safety

  1. Never look directly at the sun during an eclipse! Always use eclipse glasses or other kinds of viewers.
  2. Glasses must comply with the ISO 12312-2 international safety standard for direct viewing of the Sun.
  3. Watch for fakes! Counterfeit glasses will be sold as eclipse day approaches. Real eclipse glasses block out all light, except the direct Sun.
  4. Sunglasses are not sufficient eye protection.
  5. Binoculars and cameras need their own solar eclipse filters for viewing the eclipse; wearing eclipse glasses while looking through these devices without a filter can damage the technology, and burn a hole through the glasses and onto your skin.
  6. Only once totality hits at 3:23:03 pm - 3:24:30 pm, can one safely look at the sun without eclipse glasses, and photograph the sun safely without filters.
