VIOFO CPL Filter Anti-Glare Circular Polarizing Lens for A229/A139/A139Pro/T130/WM1 Dash Cam

Helped to remove glares and reflection.Installation was easy.Would be great if it is available for rear Dashcam as well

If I wasn't into photography, I probably would have no idea what a circular polarizer does. This filter reduces glare from the windshield which is definitely a problem for dash cams. The results aren't nearly as drastic as my actual circular polarizers for my mirrorless camera, but comparing two dash cam clips with and without the CPL filter, I can definitely tell it's working. It was able to reduce some of the reflection of the defroster vents and completely removed the white haze over the whole windshield. Definitely recommend.

This Polarizing lens cover does a good job of reducing glare on my VIOFO a229 camera. I had a bit of difficulty installing it because it didn't come with any instructions and I didn't notice or realize the there was a line or dot that had to be lined up. Once I clued in...it went on snug and has stayed on for months.

Ricevuto per sbaglio la lente polarizzata per un altro modello di dashcam viofo, il venditore si è subito premurato di mandarmi quello giusto senza nemmeno volere indietro quello sbagliato. Oggetto ottimo per la mia viofo t130, niente più riflessi del sole e immagini molto più nitide.

A must have to reduce glare from the windscreen

For a while it was not reducing the glare due to bad installation. Recently I rotated the white line that is on edge of the lens upward and now it eliminates all the glare.I am happy with this product.
