Consider green eyes.
How to do get at the 'wriggly' different shades of green?Some 'green'
eyes are less brilliant than this and merge into 'hazel', and perhaps that's commoner, and for these the image of tangled pond weeds seems more appropriate. The temptation is to
go for some precious stone image, where the connotations might themselves be too 'precious' - emerald eyes (or is it 'isle'?). Or you could go for marbles! Or, taking the pupil to be a whole, those minds with a whole in the middle. 'Eyes as green as grass' has a nice earthy feel to it. My own eyes are green to hazel and of course most bewitches, although the image of 'pond weed' could be modified (in some people's mind's) to 'pond slime' perhaps - a sort of irresistible one-night-stand and-run-aura, perhaps - (well in the green eye of the beholder in the mirror)
An image for the lashes? Anything but spiders.
