Your lenses are just as important as your frame in determining the look of your spectacles and higher index lenses have been designed with this in mind. The material used in our higher index lenses is the latest lightweight optical-grade plastic. This means they are remarkably thinner and flatter than conventional lenses - with no compromise on optical performance. Areas serviced: Lambethwww.paineandhunter.com55 Lordship Lane, SE22 8EP
