What are Eclipse Glasses?

With the excitement about upcoming solar eclipses building, it's important to understand how to safely observe an eclipse. So you may be asking what are eclipse glasses?  Staring directly at the sun is extremely hazardous to the eye and may cause permanent damage to the retina. Tempted to observe the sun during an eclipse without suitable eye protection?  Don't be fooled by the lower light levels experienced during a solar eclipse! 

Eclipse glasses are solar filters designed for direct and safe observation of the sun. ISO 12312-2:2015 is an international standard which details the requirements for a safe solar viewer. The primary requirements are:

  • The filters allow only 0.00032% of the sun's light through
  • The filters must be free of any defects, such as scratches and bubbles
  • Handheld viewers must be large enough to cover both eyes.
  • Labeling must include the name of the manufacturer, instructions for safe use and warnings of the dangers of improper use
