I also suggest you try the Ole Henriksen Total Truth Eye Cream with SPF 15- it's slightly more natural in ingredients, lightweight and also has the SPF coverage you desire.
This is a great strengthening, firming and hydrating eye cream that is gentle and smoothing- try to visit your local store for a sample!
Murad makes a good eye cream. It's the once with Vitamin C. I don't think a lot of the natural companies are making too many options with SPF yet but they should! I sometimes use the Boscia Illuminating UVA/UVB SPF 30 under my eyes. It's got the protection plus it brightens the under eye area with the white cast and the "illuminating" reflects in it.
