Why do artisans paint Goddess Durga idols' eyes last for Durga Puja?

Artisans paint the eyes of Goddess Durga’s idols last for Durga Puja in a ritual known as Chokkhudaan, which translates to the offering or bestowing of eyes. The ritual symbolises bringing goddess to life and invoking her presence in the idol. Traditionally, the eyes are painted on the morning of Mahalaya, the official dawn of the Puja season, TOI reported.
