Razer Anzu Smart Glasses: Blue Light Filtering & Polarized Sunglass Lenses - Low Latency Audio - Built-in Mic & Speakers - Touch & Voice Assistant Compatible - 5hrs Battery - Rectangle/Small

The glasses came in an awesome box! For what they're priced for, they have pretty decent sound; they're more adequate for an office setting. I tried using them while going out for a walk and I had to switch to my headphones.I got the large round frames and they are very comfortable.Please be sure to charge before using them. It's pretty straightforward once they're paired via Bluetooth.

I received it in excellent condition. This is my second purchase. The first one was from another seller, but it snapped into two pieces because I wasn't careful. I need this because I already have prescribed lenses from the old one which costs 3x more than the smart glass.This is the only smart glass in the market that isn't goofy-looking. I wear it every day, it doesn't cause any skin irritation. Also during motorcycle rides, I get to listen to music, map directions, and voice assistant without blocking the sounds around me.

They are only for some use cases. For example, They come with outdoor sunglasses for UVA and UVB which is super lovely however if the wind is blowing or you are on a bike you will not be able to enjoy the audio playing fully. The audio output is eliminated by the world around you by wind and such. If you are casually walking around in a still area then you are all fine. These aren't meant for cardio exercises.I have found the use case that best fits me is sitting at the PC with the blue light-reflecting lenses at my desktop near the office window and listening to notifications on my phone or some talking podcasts on my phone. I am not using these things for sound quality at all. They are fine for podcasts.I know the original price was 200.00 and thank god they dropped them because they are not worth that by far.The build quality is fine. I suppose for glasses they should be light but they also come across as cheap. People that are complaining that theirs have broken on the arms and pivot point I assume to be using wrong as there is plenty of flex in the joint and the flexibility while providing rigidity feels just fine.Moving forward, I want to revisit some basic physics for people that don't believe that the blue light "filter" works.See, there are two main types of ways to "filter" blue light. One is through reflecting the blue light and the other is absorbing the blue light.People believe that if you can see a clear image through lenses they are not a blue light "filter." because you are clearly seeing some of the visible blue light spectra.Here is the kicker, The lenses are blue light reflecting. Meaning that this is the mechanism by which they "filter" a spectrum of blue light from reaching the user's eyes. That is why if you hold them up in certain lighting conditions you will see reflections in the lenses from between roughly 400nm-500nm. Maybe a little more into lower energy blues but, not all of the blues.to recap, these lenses REFLECT a portion of the blue light spectrum. They do not absorb blue light and that is why they are clear.PLEASE NOTE: the picture of blue light reflecting in my glasses. This is a perfect example of what I mean.Lenses that absorb blue light you have more than likely seen. They often include a greater spectrum of blue light which they absorb and have a yellowish tint. The tinting of the glasses is what "ABSORBS" the blue light trapping and dissipating it into the lens itself and not reflecting it. That is the mechanism by which blue light is "filtered" by absorption.There are 2 large downsides to either of these. One is that the reflective filtering may reflect a higher blue light spectrum back into your eyes from the world behind you when wearing them. The other is that the blue light absorbing filtering will make everything around you yellow.The decision about what is best for you is up to you. Try them both and see what you like best!As for their efficacy, For some, they work well and for others, they do not and that is because we are all different. Also part of the issue is the parameters for the testing. Yes, our eyes have evolved to see this spectrum of light. You wouldn't imagine there isn't an inherent danger or issue in it but when you define the use case as being within the bounds of the natural light cycle of the earth a lack of impact would be especially true. After all, Until the late 1980s, our eyes have evolved and been acclimated to the diurnal cycle. Meaning that there is a higher probability that our eyes are most acclimated to a cycle of sunlight (and blue light) exposure that matches the duration of daylight per day.The issue arises when we concentrate on that level of blue light exposure and go beyond the typical daylight spectrum. For example. some people may find that during the day their eyes are fine but late at night after the sunsets you begin feeling crummy and fatigued. This may be due to overexposure to the blue light in the evenings when your body is not naturally acclimated to prolonged exposure. The use case for a person like this may be just in the evening after or close to sunset.Others may have an issue with blue light due to the immediate concentration and higher exposure for just a few hours as that is also unnatural to our ocular evolution/development. Also, aging and other things are factors.When I was a child it didn't matter how long I sat in front of the PC and now that I am older I find that around noon I need to put something on so that I can combat some ocular pain in the afternoon and evening.Please, before drawing hard lines in the sand consider that there are many factors in play as to how this affects you vs. how it affects younger folks, older folks, people with eye issues/diseases, and people with vitamin supplementation versus people without.The effectiveness is greater than just the sum of you or me. There are complex variables that are not universally true for everyone.Once you start considering others the solution does not become so binary based on you alone. This is a statement that holds true to a LOT of things in life.I would like to apologize for my verbosity in this post. It bothered me when reading that a top post didn't even begin to understand the method of blue light filtering by reflection.Someone had stated that clearer lenses aren't blue light filtering and people upvoted it but it couldn't be further from the truth. It demonstrated a huge lack of understanding of high school physics.Ps, if you have a 3d printer you can find a bunch of models for the large glasses that will hold and charge them. I found a single model for the small shades and manipulated it to stick on my monitor and auto charge my glasses while away. You will have to dig around and maybe need to throw the model in tinkercad to suit your needs.Oh, pss, Getting some nose pads help with the slipping on your face! consider those also! :)

Have been using these for 2 years when working from home and these have been fantastic! Speakers still work great and can get pretty loud. Sound quality is decent and style looks good. Blue light filter helps with eye fatigue and doesn’t make everything look yellow. These do not slip off but have a good grip due to some silicon pads at the end of the arm.

You will experience with a beautiful glossy frame with two functional music legs from the frame for usually half of the year no problem. I brought three of them and these three pair all had the same problems. The battery life is pretty short, within couple hour is done for your music life.Also I brought three pairs of them for my lens, they all broke on the leg part. These smart glasses legs would snap in half usually around the end of the legs. The glossy look of the plastic feels nice, not until you starts to realized heat’s will take it way.Buy a super glue just in case if you want to get one. I’m sure this won’t worth 85dollar and customer service from razor is pretty bad on fixing reoccurring problems.
