Never look at the sun without proper eye protection. It is never safe to look directly at the sun's rays even if the sun is partly obscured because they contain harmful ultraviolet (UV) and infrared (IR) rays that can damage your eye's retina and even cause blindness.

Never use regular sunglasses to observe the sun. The only safe way to look directly at the sun is through specifically designed solar filters, using solar eclipse glasses for direct viewing and solar filters for telescopes and binoculars.
