Features: brand new and high quality The double-sided multilayer nano-coating process gives the lens high-quality waterproof, oil-proof, anti-fouling and scratch-proof performance. The use of coating light reduction technology avoids the color cast of traditional ND mirrors, and there is almost no color cast. Made of high quality optical glass, with high-definition grinding treatment, it protects your screen from daily scratches, dust, scrapes and normal signs of wear. The hard coating process can effectively protect the lens, the thin frame has no dark corners, the light transmittance is high, and the multilayer coating reducesLow light refraction effect, no color cast, improve picture quality. Adjusted in a strong light environment through multi-layer optical lenses to prevent overexposure, resist scattered light, increase color saturation, make the picture more transparent and beautiful, and achieve large-scale effects such as foggy water and night light tracks.
