WebSep 12, 2024 · Figure 2.6. 1: The cornea and lens of the eye act together to form a real image on the light-sensing retina, which has its densest concentration of receptors in the fovea and a blind spot over the optic nerve. The radius of curvature of the lens of an eye is adjustable to form an image on the retina for different object distances. WebOC = Optical Center of Lens (that point on a lens through which a passing ray is not deviated). Provides best VA when line of sight is lined up with the OC.
