VIOFO Circular Polarizing Lens CPL Filter for Use with A119MINI2, A129 Plus Duo, A129 Pro Duo, A119 V3 by VIOFO

If you own a Viofo dash cam, then this CPF filter is a must-have that will greatly reduce the glare during both daytime and nighttime driving.
1. The CPL filter slightly darkens the video. To offset this effect, you can increase the exposure in the dash cam setting up a notch.
2. The polarizing film is taped onto the lens which doesn’t produce a smooth finish. This doesn’t affect the video quality but the film might wear off over time. It would be nice if the lens itself can be polarized instead of using polarizing film tape.
3. The CPL filter can’t be rotated to adjust the polarization angle.
4. The filter can easily be attached to the dash cam lens by sliding it on from the side.

Works fine (suppresses reflections of the top of dash from the camera), but cost is ridiculous for what it is.
Side note for those with an understanding of electromagnetic radiation, aka light: this filter linearly polarizes the light, it does not circularly polarize the light. The physical opening is circular, hence the ‘circular’ in the name

Item worked great, there was no lens flair. Even when the sun was going down. Installation was a breeze too, it just snapped on.

I received an open box product. It was clearly used as I could see finger prints on the lens too

My Viofo dashcam videos have a lot of glare from my windshield and black dash on the car and it kills the video quality on bright sunny days. Enter the CPL filter and it helps block out a lot of the glare for great quality videos any time of day.

This polarized lens is a must-have if you’re using a VIOFO dash cam, especially during daytime driving. It noticeably reduces windshield glare and reflections, giving you clearer, more detailed video footage.
Pros:
• Reduces windshield glare and dashboard reflections
• Improves image clarity and contrast, especially in bright sunlight
• Simple to install—just clips on and stays secure
• Adjustable rotation to fine-tune polarization angle for your setup
• Protects the actual camera lens from dust and scratches
Cons:
• Slight darkening of footage in low-light/night conditions (expected with any CPL)
• Adds a bit of bulk to the camera profile—barely noticeable, but worth noting

If you have the dash cam, you should get this as well. A polarizing filter has been used by photographers since before anyone reading this review has been born. It reduces reflections and glare and gives you a better picture in most situations. Installing it couldn’t be easier, snap and it’s in place.

Easy install, you just clip it on and that’s it. Work as expected.

Good product, cuts down the glare on the windshield.
Highly recommend
