Can You Look At A Solar Eclipse Through Sunglasses

Safe Solar Viewing: Protect Your Eyes During the Eclipse

ISO 12312-2 Certification: The Standard for Safe Solar Viewing

When observing a partial or annular solar eclipse, it is crucial to use approved solar eclipse glasses or handheld solar viewers with a filter designation of ISO 12312-2. These filters are thousands of times more protective than ordinary sunglasses or homemade filters.

Ordinary Sunglasses and Homemade Filters: Insufficient Protection

Ordinary sunglasses, even very dark ones, and homemade filters are not safe for viewing the eclipse. They do not provide adequate protection against the sun's harmful ultraviolet (UV) rays and can permanently damage your eyes.

Solar Retinopathy: A Serious Risk

Looking directly at the sun, even for a short period, can cause a condition called solar retinopathy, which is a type of partial or total blindness. This damage can be permanent and irreversible.

Safe Solar Viewing Glasses: Protect Your Eyes

To safely view the eclipse, the American Astronomical Society (AAS) recommends using solar eclipse glasses or handheld solar viewers that meet the ISO 12312-2 standard. These devices block harmful UV rays and provide a clear view of the eclipse without compromising your eye health.
