Eclipse Safety
Viewing the solar eclipse is exciting and there are ways to enjoy the event safely. Even if you do not plan to watch the event, these tips are important to know to protect you and your family’s vision.

- You shouldn’t be able to see anything through certified solar eclipse glasses except the sun.
- Make sure your eclipse glasses are free of bends, scratches or other defects and do not wear them if they are damaged.
- Ensure that your eclipse glasses fully cover your field of vision, you may need to hold down the sides.
- Put on your glasses before looking at the Sun and look away from the Sun before taking the glasses off.
- If you don’t have eclipse glasses, there are other ways to safely watch an eclipse.
- Make a paper pinhole projector or a box projector. Be sure to understand how to use it and never look at the sun through the pinhole.

- Do not look at the eclipse through a camera, phone, telescope, or binoculars, even with eclipse glasses.
