What is the best recommended window film for blocking UV ? I’d like as little light reduction as possible but blocking all UV. I need to block my house windows and car windows. My wife has discoid lupus.
I had my car windows tinted at a local garage which isn't helpful to you living so far away from here. However, I was advised that the darkness is more for aesthetics and all of the tints had the same level of UV filter so you may be able to source one that doesn't make the car really dark. I have heard that Dermaguard is a good make but again I'm sorry that I don't know if you will have this available in your part of the world.
Sorry I can't be more help, hopefully someone else will be along soon with more helpful information.
I recently had the 3m Ceramic series window film installed on my car. It is barely noticeable. The legal limit for front windows in my state is 70% visibility and we purchased the 80%. I am very happy with the purchase. I am able to drive to and from work without feeling ill.
