The MC5619 has always been a bestseller in previous years. The lens connection adopts an assembly design, so that when users feel the distance is too far, they can adjust it to meet their needs. At the same time, the lenses adopt electroplating anti-fog technology. On the one hand, it can prevent the lenses from fogging up during use; on the other hand, it can block the damage of ultraviolet rays. The mirror strap can also be adjusted to achieve maximum comfort.
