What Are Eclipse Watching Glasses
Eclipse watching glasses are specialized eyewear designed to let you view the sun safely during a solar eclipse. They use solar filters that block harmful ultraviolet, infrared, and intense visible light. Unlike ordinary sunglasses, they meet international safety standards for direct solar viewing.
Why Eye Protection Matters
Looking at the sun without proper protection can cause solar retinopathy, a burn to the retina that may lead to temporary or permanent vision loss. Eclipse watching glasses reduce the sun’s brightness to a safe level, allowing clear viewing without damaging your eyes.
How to Choose Safe Glasses
Choose glasses that are ISO 12312-2 certified and clearly labeled with the manufacturer’s name and address. Inspect them for scratches or damage before use.
