Exposure in the 350 to 1400 nm range primarily harms which ocular structure?

Explanation:
Different ocular tissues absorb different parts of the spectrum, and protective filtering occurs as light passes through the eye. Exposure from 350 to 1400 nm includes visible light and near-infrared light. The cornea and lens absorb most of the shorter UV wavelengths, shielding the retina from UV damage, so the energy that can reach deeper structures comes mainly from the visible to near-IR part of the spectrum. The retina is particularly vulnerable to this energy because photochemical damage from blue visible light and potential thermal effects from near-IR can affect photoreceptors and the retinal pigment epithelium. With this range, the retina ends up being the primary structure at risk.
