Today, many new cars contain smart glass: car windshields and windows that have integrated SPF to help block the sun's harmful rays. But many older cars do not have this feature, which means people who spend a significant amount of time in those cars can get sunburned or worse from the sun's rays permeating the cars' glass. Instead of replacing it with costly new glass, you can invest in clear sheets that cling to the inside of the window and effectively block 99% of the sun's harmful UV rays while helping to reduce glare. They're a cinch to install and nearly invisible once they're in place.
