Replacing UV-damaged plastics, particularly the camera lens

My Ring Video Doorbell Pro is 3 years old and gets full sun exposure for several hours every day. Over time, the plastics have developed a haze, similar to a car's plastic headlight housings. The button is also worn, but that is just cosmetic. The haze is bad enough that motion detection is no longer functional. Ring does not seem to sell service kits for this model, so they will only offer a discount on a replacement unit (which I presume will suffer the same fate). I'm curious as to whether there is any treatment I can apply as a preventative, or if indeed the front clear plastic panel can be replaced.
