#14 shade welders glass is approved by essentially everyone to view the sun. A typical arc welding helmet often has #10 shade which is not enough protection so verify #14 shade to be sure. Also all "Eclipse glasses" marked with CE or ISO showing that they have been tested and approved. Baader and Thousand Oaks provide solar filters for both visual and photographic use, so make sure you choose one with #14 shade protection or higher.
