While glasses were absolutely necessary for last year's solar eclipse, they are not needed to safely view this year's total lunar eclipse.

Earth’s shadow will block most of the light that illuminates the lunar surface, creating what is known as a blood moon.

Total lunar eclipse – The entire Moon moves into Earth's shadow and turns red. Partial lunar eclipse – Only part of the Moon enters Earth's shadow, creating a visible dark section. Penumbral lunar eclipse – A subtle event where the Moon passes through Earth's outer shadow, causing a slight dimming.
