Thanks to the Seller.
Works very well. I search for amber by the sea with UV light(UVA from LED light torch that emits 395nm - 400nm light) using these. The glasses protect the eyes very well while without them I can feel eye discomfort just after few minutes when looking at the UV light. With the glasses no discomfort at all after a few hours, and it improved the visibility of objects glowing under UV light a lot. Works even better than I expected. I don't know about other types of UV light like B and C, but it definitely protects from the UV light I use very well. The glasses are also comfortable and even look very nice as for protection glasses.
