Filters Off During Totality
The only time when it’s safe to remove your protective glasses is when a total solar eclipse reaches the full totality phase — the brief period when the moon completely blocks the sun. Proper eclipse safety requires that you wear eye protection during partial eclipses, annular eclipses, and the partial phases of total eclipses. Even when the moon is blocking 99% of the sun’s face, that remaining 1% of the photospheric crescent can still cause severe eye damage.
