The eyelids contribute to the Shweta / Shukla Mandala
Mandala means circles. Shukla Mandala is the circle made up of sclera along with the conjunctiva covering it. Seen from outside, the white of the eye i.e. sclera / outer tunic of the eye, looks like a circle.

Sclera contribute to two sandhis i.e. joints of the eyes
Vartma Shukla Gata Sandhi – This is the meeting place of eyelids and sclera (Shukla bhaga).

Shukla Krushna Gata Sandhi – This is the meeting place of Shukla Bhaga (Sclera / white of the eye) and Krishna Bhaga (Black of the Eye / Iris).
This can be considered to be the sclera-corneal junction / limbus. But since Cornea is transparent, it is wise to take Iris as Krishna Bhaga.
