Principle The CPL polarizer filter uses light polarization. It consists of two lenses, one fixed and one rotatable. When natural light passes through, light polarized in a certain direction is filtered out, reducing glare and blur and improving contrast. Design Embedded silicone anti slip strip enables one step installation. The buckle provides anti slip protection, keeping the filter stable even on rough rides or during vibration. Easy to clean Oleophobic and waterproof coating offers strong protection. Cleaning is easy: wipe gently to keep the mirror surface clean and bright. Clarity Eliminates reflections and glare with no color cast. By reducing light waves vibrating in all directions, the image remains clearer and more true to life. Applications Landscape photography to reduce water glare and enhance skies Photography through glass or on shiny surfaces such as windows, cars, or chrome Outdoor scenes with reflective surroundings like water, snow, or wet surfaces to improve overall image clarity
