Anti glare filter?

[Inazuma]

Hey
I have a 16" HP HDX laptop, and the glossy screen is driving me up the wall! Can anyone recommend me something to buy to reduce the reflection/glare?

Edit: Actually I think it's anti-reflection that I need. Anti-glare would be for when the sun is pointing directly at the screen right?

Guessing google came with the same, Anti-Glare Filters should do the trick?

Looks pretty expensive, depends how much time you spend outside I spose, but £80 maybe dont get a gloss finish screen next time
