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.

For the first time in over two years, a total lunar eclipse known as a ‘blood moon’ will be visible this Thursday night into Friday morning. The eclipse will last over three and a half hours and can be seen across North and South America.
