Westglass Photochromic Film Series is an innovative functional film that integrates smart light adjustment, energy-efficient protection, and aesthetic design. Its core technology relies on special photochromic materials that undergo reversible molecular structural changes in response to ambient UV intensity, dynamically adjusting light transmittance from 75% to 20%.

The film darkens rapidly in strong sunlight to block glare and restores high clarity in low light conditions, providing seamless stepless switching for enhanced visual comfort and reduced air conditioning energy consumption.
