You might want to calculate the local power density when one looks at, say, a 100 W light bulb from one meter distance (with certain assumptions about size of the pupil). Convective heat transfer by the blood is probably the main mechanism to maintain temperature. Also - what fraction of invisible radiation is absorbed in the vitreous humour? | |
