light-adapted eye

Though the stars must be shining out there, his light-adapted eyes could see nothing but black emptiness beyond the curve of the great window.

A light-adapted eye generally has its maximum sensitivity at around 555 nm (540 THz), in the green region of the optical spectrum (see: luminosity function).

The sensitivity of the dark-adapted human eye is greatest at about 507 nm, a bluish-green color, while the light-adapted eye is most sensitive about 555 nm, a yellowish-green color.
