Glasses and Video Work Calls ✔️
I bought Zenni glasses and I love them, but the blue light glare is insane during video calls. I couldn’t even see my eyes in the call and was a little embarrassed you could just see my screen reflected back even angling my head. I saw this was a hack to put onto the webcam and just adjust it to fit and it significantly reduces the glare! There is still a slight glare off to the side or at the bottom but it ABSOLUTELY does what I purchased it for! I was hesitant paying over $10 for something, but this is 100% delivering on value for the price. It even comes with a case, so I don’t feel bad popping it into my bag when going to work. When I have a video call I just take it out and put it over my laptop camera and make sure it’s adjusted. It is a little odd getting used to navigating the screen underneath it, but it’s worth it. If you’re looking at this because you have glasses and are looking to reduce glare, I do recommend you trying it out!

Perfect and inexpensive solution!
It is easy to set up. All you do is put the lens in the holder and clip it on. In my video I have it on in the first part and took it off for the second. It's a big difference in what my clients can see. I'm very happy with this device.

Quality
Image quality is extremely poor. Every photo is blurryand the polarizing effect is almost non-existent.

It’s ok
This item didn’t work well with my iPhone, the quality isn’t all that great, you can adjust the lens slightly but there was not major difference. Don’t waste your money or time.

Solved my glare problem
This was just the thing I needed to adjust the glare from my glasses.

Professional Photographer
I have no idea why the "bad" reviews are saying these are not polarized. I've been a professional photog for 20+ years and you can test if a lens is polarized by using a known polarized lens - If the light dims or goes black at a certain angle, your camera lens is polarized. If there’s no change, it isn’t. This product IS polarized. Anyway, I bought this for my mother because she needed a clip-on, or else I'd have given her one of my lenses. Here's a screenshot she sent me using a Macbook (don't blame me for lack of clarity in the pic, she took it). Anyhow, to make these work, you can't just pop it on and start turning the dial and think "voila." No. You have to "tune" it. This is a a CPL lens. Since a CPL blocks some light, rotating it can slightly affect exposure, usually by 1–2 stops. That's how it works on a camera, and this is no different. It works BEST if your light source is above you, or DIFFUSED from the side, such as with a diffused ring light or an equivalent "soft box." If you have too much harsh, non diffused light, on your left or right, it will only work on one side of your glasses. If you turn it too much, it will go back to glare, you have to be slow with it and go back and forth until you hit the sweet spot. Cons: The only thing that bothers me about this lens, and it's serious, is it's too tight and cannot be loosened - unless you know what you're doing with some tools. It's a spring loaded clamp. The issue is, if you use this on a MacBook, which is very thin, it's so tight that it could easily damage the camera via the pressure. I would NOT put this on a MacBook unless you loosen the pressure. The only way to do that is by bending the clamp anchors. Not too hard. If you look on YouTube, 'how to fix a broken hair clip', you'll see how spring loaded clamps are put together/disassembled and be able to fairly easily loosen it. Tip, if the green light on your camera is causing glare, put a small piece of black paper over the light with the tiniest bit of tape and problem solved. Don't use a 'camera cover' for the light if you're on Mac because if you close the lid with one of those one, it can damage the camera.

I would purchase again...
This polarizer lens filter fits onto my Android easily and works fairly well to cut down on glare. It doesn't take the glare away completely but I'm still very happy with how much it lessened the glare when taking certain types of pictures with my phone. If something happened to this clip-on polarizer lens filter I would definitely purchase another one.

No more glasses glare!
I am so grateful this eliminated the glasses glare. Great price, fits my external computer camera well, low profile and fits nicely on the camera. Totally recommend.

Works Well for Reducing Glasses Glare in Video Calls
I bought this to solve a very specific problem: strong glare on my cat-eye glasses during video calls. The lenses reflected everything - windows, blinds, lamps, even my computer screen - and you could barely see my eyes. It was distracting and honestly a bit embarrassing during meetings. After seeing a suggestion in a YouTube video, I placed this polarizing lens over my iMac’s camera - and it completely solved the issue. The glare disappeared immediately, and my eyes are clearly visible during conference calls. I can’t speak to other uses (such as phones or different camera setups), but for my iMac camera and regular video meetings, it works perfectly.

Excelente calidad-precio
Había leído muchos review malos pero creo que se trata de saber usar un equipo fotográfico antes de todo. Claro está que no hace milagros por el precio, pero es un excelente accesorio y hace su trabajo. Recomendado!
