Wow, reading this NPR article (actually, I listened) surprised me several times:
- Damage to your eyes may not show up until the next day.
- If you stare at the crescent, that is the shape of the damage to your eye.
- Glances can hurt your eyes - the damage is cumulative.
This is worth looking at if you intend to watch the solar eclipse on the 21st of August. BE CAREFUL - WE WANT YOU TO BE ABLE TO SEE OUR SIGNS CLEARLY!
