I can recommend: Headlight Restoration
Following my last ITV test I received an advisory regarding my sun damaged headlamp lenses. I thought I would ring a number from a leaflet left under my windscreen for Headlight Restoration Total price €25. I rang the number and the guy was at my house within the hour, spent 40 minutes solid work and when he finished they were like brand new. He even gave me a maintenance sheet to maintain the finish. His number is 634 59 14 16. I can only speak as I find.
