Orivens Avis 

If I could give negative stars I would they won’t let me return them because they’re customized so the only option is to ship them and get them adjusted but you have to pay for that…. Don’t waste your money!!! Highly recommend to go with hero loupes or one of the big brands since they all walk you through the steps and all have better customer service then these dib shits

Don’t buy them they say you can return it but you can’t. Because they are customized to your face because of the IPD and working distance they’re considered customized even though you need those measurements to order them. Like wtf then every pair of Loupes are not returnable if that’s the case. They are also cheap feeling like they just cut the frame from a sheet of metal no bends or anything to the curvature to a human face or anything do not recommend buying waste of $1,500 literally just a paper weight

I bought a pair of loupes 6 months ago and they are falling apart from normal use the lens literally de attached and fell out on my patient’s face. On top of everything I sent an email with a video to see if they have some kind of warranty but they only offered mea repair and wanted to charge me almost $400 on top of the $ 1400 I paid for them. DO NOT BUY THIS

If you are considering the Orivens head loop for detailed work, you may want to look elsewhere. Instead of being a practical magnification tool, it functions more like an overpriced desk accessory.
Here are the primary issues with this product:
* Extremely Restrictive Focal Point: The margin for error is essentially non-existent. You have to lock your head and neck at the exact focal distance to see anything clearly, making natural movement while working completely impossible.
*Causes Physical Discomfort: Because the viewing window is so unforgiving, attempting to work with these loupes quickly leads to severe eye strain. Slipping even a fraction of an inch out of the precise focal point immediately causes headaches and dizziness.
* Zero Practical Utility:The rigid posture required to maintain focus entirely defeats the purpose of the tool. It is far too disorienting to use for any actual, prolonged work.

The Verdict: Save your money. This is nothing more than an expensive ornament. It will give you a migraine long before it helps you get any actual work done.

I got ergozen loupes 6.0x with zenlux.
The clearity is great. However my 4.0x from another company (prismatic loupes) seems to have higher magnification than these 6.0x. So thier x6 is actually x3 in reality. So I’m sceptical that they really are 6.0x. Zenlux lamp is also good, however they surely are not up to 100k lux. They are comparable to my 20k lux from another company, maybe slightly better. Otherwise, alll overall i like them, but really not 6.0x

I choose the ErgoVision TTL after using flip-up straight loupes for years, manly to reduce weight and improve stability during procedures. After several weeks of daily use, I can say the transition was worth it. The build quality feels professional and well thought out. Everything feels solid without being heavy, and the frame remains comfortable even during long sessions. I am please with my purchase, which seems to be a fantastic deal also in terms of price. Cannot be happier with my new ergo. I am definitely recommending going with Orivens loupes and their amazing and supportive team (thank you, Fred, for all help!!).

I was initially skeptical because I didn't know the company, but after speaking with a colleague of mine who was happy with his purchase, I decided to give it a try, and it was a great decision! I now own a 6.5x Orivens Ergo loupe. The titan frame is robust, and the magnifying barrels are not heavy at all. The view from the lenses is excellent, and my back pain is already getting away after only 3 weeks. Not to mention that it took only 18 days from the moment I placed the order till the delivery day, and I paid probably half of the price if compared to more famous brands. I can't recommend these guys enough. Thanks!
