Bluestone Sunshields are tested according to the American National Standards Institute.

UPF stands for Ultraviolet Protection Factor. A rating of UPF 50+ means that the fabric blocks at least 98% of the sun’s harmful UV rays, allowing less than 2% to pass through. In other words, it provides excellent protection against both UVA and UVB rays—helping to shield your skin from sunburn, premature aging, and long-term sun damage.

The best way to travel with your Bluestone Sunshield depends on your needs. You can use the convenient travel bag that comes with the sunshield, tie it to your travel bag for easy access, or opt for the Full Lux Hard Case for added protection and durability during your journey.

Absolutely! The UV-blocking material in Bluestone Sunshields is embedded directly into the lens itself, not just applied as a coating on the surface. This means that even if the colour fades over time, you’ll still enjoy excellent UV protection. It’s a design that truly prioritises both quality and long-lasting performance.
