How is the diamond ring effect caused?

The Baily’s beads effect, or Diamond ring effect, is a feature of total and annular solar eclipses. As the moon goes by the Sun during a solar eclipse, the lunar limb topography allows beads of sunlight to shine through in some places, and not in others. The effect is caused due to the rugged lunar surface.

Exposing your eyes to the sun without proper eye protection during a solar eclipse can cause “eclipse blindness” or retinal burns, also known as solar retinopathy. This exposure to the light can cause damage or even destroy cells in the retina (the back of the eye) that transmit what you see to the brain.
