UV is mainly used to prevent fingers from touching the lens and dust from entering the lens. As for the function of filtering ultraviolet rays, it is second.
In addition, before using filters such as CPL, remove the UV as much as possible to reduce the chance of imaging circles and improve the image quality.
When facing the light source, especially the night scene, please remove the UV. Otherwise, the glare caused by the uneven lens will be more severe. After all, it is not an integrated lens, and Luokou will inevitably have errors.
