Screen Glare

I do alot of camping and using the MacBook Pro outside. Is there something out there that I could use temporary for the glare. I don't want to use it all the time but off & on.

Thanks ahead - more camping coming.

A number of companies make films that you can apply. Not sure how easy it is to get on and off, but a quick Google turned up this one:

Contour 15" Privacy Filter/Anti Glare film for MacBook Pro - Apple Store for Business (Suomi)

Thanks But...

would love to "hear" from someone who has tried one AND likes it...
