Cut off reflections and glare It cuts off reflections and glare from glass, metals or shiny surfaces that would damage image quality, this works in the same way as polarized sunglasses. 3. Make colors more saturated It cuts reflections from surfaces like leaves, grass or walls, making colors appear saturated, and shadows appear blacker.

Review: No need to blindly try to adjust it... - When I first got this filter, having looked up multiple videos and posts online about how to adjust it if it was not adjusted properly, the first thing I did was do what all those videos said to do. I held it against my mobile phone screen which was displaying an image of protractor, on which was highlighted a red line at a 45⁰ angle. I twisted the filter so that at 45° from it's horizontal fitting position it was supposed to completely cut out the light from the phone screen. Three things then: 1. It does not cut out the light at 45⁰. 2. It does not cut out the light completely as shown on video in any circumstance. 3. It only cuts out the light to the maximum extent that it can when twisted to 0⁰ (vertical) and not at 45⁰. Point 2 may be because of video photography, lighting and metering on whatever was used to record the videos. Anyway, I initially thought that the filter wasn't aligned properly, but before man-handling the lens in order to turn it I tried something else which made more sense. I sat in my car holding the lens in the proper orientation, long slit up, front facing windscreen and at the same angle as the lens was set on the dashcam (basically vertical and horizontal to the windscreen). I was holding it at a distance from my eyes where I could see the reflections on the windscreen of the side pillars, speaker grilles and vents on my dashboard. It was not a bright day but they were visible on the windscreen. Whilst looking through the filter they disappeared. Twisting the filter to the left and right I saw the reflections coming back into view. At no point other than at the level proper position for fitting did I see an improvement in how it reduced reflections. So obviously the only assumption I could make from this is that it arrives pre-set and in it's correct orientation. In my opinion blindly following the instructions online is a mistake because when mine was turned 45⁰ I could see all the reflections. The videos online are all dated from and around 3 years ago. Maybe something has changed since then, I don't know, but physically looking through it in the orientation that it is intended to be utilised, the pillars, speaker grille and vents all vanished. It was a dull day so there weren't really strong reflections from the dash itself but my pillars are light cream, and they weren't visible any more. So in the end I put the CPL on the dashcam without forcing an adjustment to make it block out the maximum amount of light it can at 45⁰ as the videos all indicate is correct, and I left it at it's preset 0⁰. I do not really know why adjusting it like they do on youtube is necessary but I suggest you do the same as I did before blindly trying to adjust to a chart on a screen. Sit in the car and look through it. I think Viofo are reputable enough to make sure that the manufacturers adjust these properly before supplying them. While I was looking through it during the test, though It certainly added definition to the scene it also definitely lowered the light passing through it, as it obviously would. Please see the oictures I've uploaded and look at the vents reflections vanish. I used to take photographs a lot, back in the days of film and more recently with digital autofocus SLR cameras. Regardless whether it was a linear or circular polarizing filter, I used to adjust exposure up slightly when using one. I did the same with the A119, adjusting it +⅓, further testing will see if I need to adjust it one stop higher or even back to 0, depending on how the sensor copes with the reduction. In a perfect world it will adjust itself but I need a bright day to do those tests. As for cost, it is expensive for what it is. But that being the fact should also mean that it arrives configured to immediately be used from the box, with no adjustment. I think reducing the glare, especially on sunny days is worth it.
Review: Brought for Dashcam - Brought these for my Dashcam as it kept getting glare on the windscreen which you could see on the video footage. 90% reduced glare. Very happy with this and easy to fit.

## Questions & Answers

**Q: Does this need to be unclipped at night or can it be left in place permanently ?**
A: From my experience it doesn’t affect the night use too much. Still clear enough to leave in place.

**Q: Does this include 2 filters for both Front and Rear camera?**
A: Hi There.. The box contains one filter. Thanks

**Q: Is this lens vital or rare use cases? If valuable to all users why is it a $$$ extra encouraging extra shipping, rather than packaged and included?**
A: This filter is commonly used to cut down on reflections off the dash (air vents etc) spoiling a clear view through the windscreen. You can always try it without and if reflections are a problem buy it later.

**Q: When this filter is placed over the viofo lens Will this make the video recording slightly darker?**
A: No, it doesn't make the recording any darker.  However, a polariser does reduce the amount of light entering the lens, which is fine in bright conditions, but in low light/dark conditions the camera has to compensate in some way, presumably by adjusting the frame rates.  I haven't noticed it causing any problems in low light or the dark and the benefits outweigh the drawbacks, I think, so I just leave mine on all the time.

### ⭐⭐⭐⭐⭐ Brought for Dashcam
*by L***N on 18 July 2024*

Brought these for my Dashcam as it kept getting glare on the windscreen which you could see on the video footage. 90% reduced glare. Very happy with this and easy to fit.

### ⭐⭐⭐⭐ Great for day, not so great at night
*by P***C on 2 October 2020*

Brought this as seen reviews of the dash cam with it on and with it off. Works great during the day and really reduces the reflections on the inside of the windscreen where you can see the dash. The picture is so much clearer and crispy. Night is not so good for me. I've got a heated windscreen, and the night footage with the CPL filter on is not very clear at all and fuzzy. I've assuming the fine heater wires, nighttime and what the CPL does to the image just doesn't all work together. CPL off at night is better.
