[Warhammer 40K] What's up with the funky Eldar helmets?

Does their size and shape serve any purpose other than making them a more conspicuous target?

I have always figured that the helmet design on the Eldar is a cultural thing, as the Eldar seem to have a fascination with combining art with all of their creations. Thus their helmets design is as aesthetically pleasing to them as possible. It would seem that in their arrogance, they are willing to sacrifice practicality for aesthetic design. 

Although that might be an ironic statement coming from a Space Marine.
