CPL Filter Anti-Glare Circular Polarizing Lens for A229 series / A329S series Dash Cam Front Camera

This is a must buy, because it helps with sun glare at the front camera. Bought it and forgot just leaving a review for others to understand that it does do its job as described.

works perfectly

Good fit on the Viofo 229 Really cuts down on the glare but only slightly on the light at night. So, it's a very nice accessory to have as it improves the picture from your dash cam substantially.

This filter is OK. I spent about $80 buying multiple polarized filters for my garmin dash cams to try to identify the best ones and make some DIY. I broke this one multiple times in my testing. I had success removing the lense from the housing using acetone and an ultrasonic cleaner. Using heat will destroy the lense coating (thin polarized plastic laminate), using force will shatter this lense and it is extremely easy to shatter. It's actually a pretty good fit with a custom housing because it's a 26mm diameter lens, however, the garmin dash cam lense is rounded and not flush in the front like a hemisphere, so when putting this on one day it cracked the lens. I was going to originally recommend this as a cheap alternative to the garmin polarized filter but it's honestly more work than it is worth and I don't really recommend it unless you put in a gasket or some kind of spacer between this and the garmin lense because it will crack this lense with very little force.

Paired it with the A129 Pro (2K). Fits well and there was no instructions, but there is a little line on the lens and on the dash cam so I assume I just had to align it. It does make the picture quality more clear and better contrast, overall. Also, it helps with low light glare from headlights to be able to see license plates better. I do recommend it. Wish it came with it automatically, but only the 4K version has it in the box.

Installed this on my Viofo, not sure if it really made a difference.

they do work like polarized sun glasses, I tested it on a sunglasses test card. Cuts down on a lot of glare on the windshield and from other vehicle glass in the recording. One down side, the fit is not very secure, the lens cap is not very deep so can come off. Best to put a dab of silicone around the ring to keep it on the dashcam

This is an excellent way to block glare from your dash cam. Came standard with my Viofo A229 Pro, it works great, just line up the white dot on the filter with the white dot on the camera, its press fit. Recommended.

رائع المنتج يخفف من توهج الشمس ويعطي نقاوه للمقاطع المصوره

Funciona bastante bien, ayuda mucho a eliminar los reflejos

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.

It's not fitting

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.
