Safety tips:
- Only use special eclipse glasses; regular sunglasses aren’t safe
- Wait for 100% totality before taking off your eclipse glasses. (If you don’t have eclipse glasses, wait for totality before looking at all)
- Have a timer prepared on your phone set to the duration of the eclipse at your location, so you know when to put your glasses back on.
- When the sun is mostly (but not fully) eclipsed, it will likely not feel painful to look at it, but it will still damage your eyes permanently.
Why?
To remain 3 dimensional when the glasses go back on.
Green becomes extremely vibrant in the solar twilight and red turns pure black.
