Light that reflects off smooth, shiny surfaces such as water, snow, car windshields, etc. dazzles us. This causes distorted observation of colours, shapes and impairs visual comfort. Be52 sunglasses have TAC polarizing lenses that successfully block these reflections. The lenses contain a UV 400 filter, which protects against ultraviolet rays (UVR), but mainly against the more harmful UVB radiation that causes skin aging and clouding of the eye lens. Plus, it captures 100% of UV radiation up to 400 nm.
