Through controlling the vibration amplitude and direct current component of the driving wave for the varifocal mirror, we can obtain the different depth range.
通过控制变焦镜驱动波的振幅和直流成份，可获得不同的深度范围。
The lenses are available in single vision, varifocal and sun-lens forms. They need to be sprayed with a chemical solution every week to keep the fog-repellent surface working.
这种镜片有单光、变焦、太阳镜三种形式，使用时需要每周在镜面上喷洒一种化学溶剂，才能保持防雾表面持续有效。
