As the 2024 solar eclipse approaches, it’s essential to prioritize eye safety while enjoying this celestial event. Chicago will experience an estimated 94% totality, making it an exciting opportunity for skywatchers.

Here’s how to safely enjoy the eclipse:

Eclipse GlassesSolar eclipse glasses 
are your best friend during this event. These specialized glasses are designed to block harmful ultraviolet (UV) and infrared light. Wear certified ISO 12312-2 compliant solar eclipse glasses to protect your eyes. Regular sunglasses, even if they’re dark, won’t suffice. Remember, a solar eclipse is only safe to view without glasses during 100% totality.

Pinhole Viewer: Create a simple pinhole viewer using two sheets of white paper (card stock works best). Follow these steps:

  • Poke a small hole in the middle of one sheet.
  • Stand with your back to the sun.
  • Hold the sheet with the hole over the other sheet.
  • Adjust until you see a small dot of light—the sun!
  • As the moon moves across the sun, you’ll observe a crescent shape.

Solar Filters for Telescopes and Cameras

If you plan to use a telescope, binoculars, or camera, ensure they have proper solar filters. Consult the manufacturer for the right filter to attach. Using these devices without protection can cause irreversible eye damage within seconds.

Beware of Counterfeit Glasses

Unfortunately, counterfeit solar eclipse glasses exist. They may appear fine but could allow harmful UV and infrared light to pass through. To detect real glasses, look for the ISO certification (ISO 12312-2) and purchase from reputable sources.


Remember, your eyes are precious, and irreversible damage can occur if you view the eclipse without proper protection. Enjoy the 2024 solar eclipse safely, and marvel at the cosmic spectacle! 🌞🌘
