Whether you’re traveling to a destination or staying locally for the solar eclipse, do yourself and your eyes a favor by getting properly made ISO 12312-2 certified filters and/or viewers from reputable vendors. There are already many knock-offs and fake products flooding the market so be careful what you use as you can severely and permanently damage your vision and retinas by using the wrong products.
