We are planning in advance of the 2024 North America total solar eclipse. We ordered at 10PM on a Monday and they were in our mailbox by noon on Wednesday! They are very lightweight and worked super well for my partner (who does not wear glasses). I had to adjust a bit to accommodate my glasses, but they do work, if you are careful. A brimmed hat also helps, as glasses increase the eye relief between you and and the solar eclipse glasses. We *love* them and will use them even before the eclipse. And we *loved* supporting this California-based company, as we are Californians, ourselves!
