Now let's talk about 1.7 1 lens in detail. 1.7 1 lens is a patented product of yue mingjing lens. In the past, there were only two kinds of lenses with high refractive index, 1.67 and 1.74, but 1.67 was still thick and heavy, which was harmful to the bridge of the nose. 1.74 lens is thin, but the price is too high and the cost performance is too low.
