With several eclipses on the horizon, there is no better time to
prepare than now! The only way to safely view a solar eclipse is with these new and improved Eclipse safe solar glasses. Eclipse glasses are
exclusively manufactured with 2 mil scratch resistant polymer
(black/silver) lenses that filter out 100% of harmful ultra-violet and
infrared rays and 99.999% of intense visible light. Our premium eclipse
filters create the sharpest solar images with a natural orange color.
With an optical density of 5 or greater, these ISO 12312-2 compliant and
CE certified eclipse glasses are independently tested and safe for all
phases of the eclipse.
