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. WebEven if the lens' curvature is not circular, it can focus the light rays to a point. It's just an assumption, for the sake of simplicity. We are just learning the basics of ray optics, so we are simplifying things to our convenience. Lenses don't always need to be symmetrical. Eye lens, as you said, isn't symmetrical.
