  Solar eclipses, as rare astronomical events, often evoke a profound sense of
wonder and awe within the human spirit. However, for ordinary people, the
extremely short preparation time, a few hours of notice from friends or social
media, and the lack of observation equipment often hinder safe and effective
eclipse viewing. Some individuals directly observe the sun with their naked
eyes, risking vision damage. To enable ordinary people to safely observe
eclipses in very little preparation and reduce the risk of vision damage, we
present a simple and safe method that almost anyone can use under very basic
conditions, known as the "Okay" observation method.
