What do your Elven eyes see?

[Estelyn Telcontar]

An early morning winter walk, with stars still shining, reminded me of this movie quote and got me to thinking about Elven eyesight. Now, according to Tolkien's mythology, the Elves awoke under the stars - and it was long before the sun was created. That means that they did everything - reading and writing, arts and crafts, all the things of daily life - by a minimal amount of light.

Granted, we don't know if the stars may not have shone brighter then than they do now, but it seems to me that their eyes would be different than ours. I'm not an expert, but as I remember from biology, the pupils regulate the amount of light that enters into the eyes. Do you suppose they had more sensitive pupils, that could adjust much more, since they would not have changed in nature after the appearance of the sun? What other differences would you suggest that would enable them to see under minimal light? Has anyone read information by Tolkien on this subject?

I'm reminded of Star Trek's Spock, whose Vulcan eyes had an additional inner eyelid to protect them from extreme light...
