Our Polarflite shades include a wide collection of frames with Actif tri-acetate cellulose lenses. They give 100% protection from UVA-, UVB- and UVC light. They effectively block both visible light and the light reflected from water surface reducing the aligned, partially polarized glare. They are finished with hardcoat scratch- resistant surface. These lenses will not absorb haze and will stay constant with a low haze value of 0,4%. A perfect choice for all-round shades. These standard polarized plastic lenses have all the optical qualities needed for fishing. They are also very light. The 2by4 is designed to be worn with the glasses. Pouch included. Made in France.
