I love Boots No 7 Protect and Perfect Intense Eye Cream. ITs about £20 but works wonders, I also use the serum on my face and within 4 weeks of starting to use both i noticed a definite improvement in puffiness dark circles and fine lines
My mum would second the No7 Protect and Perfect serum. Another good one is the Swiss Apple Serum from Superdrug. A lot of celebs including Gwyneth Paltrow use the more expensive (up to about £300!!) creams using the swiss apple cells.
clinique all about eyes is fantastic. all there stuff is...if you buy a complete range of skincare and makeup...you will be amazed (just not necessarily at the price!). but it does work x
