While Baily's beads are seen briefly for a few seconds at the center of the eclipse path, their duration is maximized near the edges of the path of the umbra, lasting around 90 seconds. It is not safe to view Baily's beads or the diamond ring effect without proper eye protection because in both cases the photosphere is still visible. [5]
For people with specially filtered binoculars or telescopes, you can zoom in seconds before or after totality to witness Bailey's Beads: the beads of sunlight coming through the valleys and around ...
However, if you look at the sun at any other time — including the diamond ring effect or Bailey's Beads that appear moments before totality — you risk permanently damaging your eyes.

The color change in the beads alerts the wearer to the presence of the radiation. When changing colour they undergo photochromism. When the beads are not exposed to ultraviolet rays, they are colorless and either translucent or opaque. However, when sunlight falls onto the beads, they instantly turn into red, orange, yellow, blue, purple, or pink.
