Although it is frequently claimed that the retina is burned by looking at the Sun, retinal damage appears to occur primarily due to<unk> hemical injury rather than thermal injury. The temperature rise from looking at the Sun with a 3-mm pupil only causes a 4 °C increase in temperature, insufficient to<unk> oagulate. The energy is still phototoxic: since light promotes oxidation, chemical reactions occur in the exposed tissues with unbonded oxygen molecules. It also appears that central serous retinopathy can be a result of a depression in a treated solar damaged eye. The duration of exposure necessary to cause injury varies with the intensity of light, and also affects the possibility and length of recovery.
