- Neuro Lenses reviewed by an Optometrist who was in engineering before optometry. Put optics and neurology before marketing, and find out what's behind the NeuroLens and what your options are.
NeuroLens is a useful tool for certain measurements, but ultimately falls short due to the limitations of the unit. NeuroLens is unable to take into account the effects of head movement on visual function (visual-vestibular integration) and completes its measurements in a very artificial environment.
So while it is better than nothing, it provides less results and less value than proper prism prescribing by an optometrist who specializes in this field.

I quit prescribing regular prism because patients kept adapting and wanting more....this is where neurolens is better. Neurolens patients don't come back wanting more prism like other patients.
I think it comes down to what type of decision making algorithm you are using for how you prescribe your prism etc. Because you're right, many of the traditional 'rules of thumb' cause prism adaptation that keeps requiring more (especially with base out prism). Unless we are talking vertical, where they naturally lose the ability to compensate for the vertical deviation over time.
"come back wanting more prism", that serves the pocket book of optometrist well, doesn't it? I hope all doctors are like you. 👍
@@stevec9669well neurolens can start at 850 just for lenses and can go up from there
Thank you for explaining the pros and cons of Neurons. I love it when professionals are so open and honest.
If affordable I will go with neurolens, because I am not that lucky to see the best optometrist who knows what he/she is doing and can give better/more accurate service/prescription than the machine!
THANK YOU for sharing your knowledge! The limited amount of information out there, mixed with complicated information coming from studies, make it very hard for consumers to know if that's the right decision for them. I was prescribed Neurolens but Prism lens weren't. Interesting, thank you!
Massive amount of respect for you!!! Thank you for the way you explained this 💯👏🙌
Amen. I watched this after my neurolens appointment and it's exactly how i feel about their prescription for me. I'm going back to my OD next week to discuss this video and the things you're suggesting. So thank you very much. The $1k price tag is a turn off, but I'm actually okay spending it, IF I knew it would work. But after going thru the entire exam with the Neurolens dude, I just had a sour taste in my mouth for it. Again, thank you!!!
Have you actually got and tried the neurolenses? If so, can you share that experience? Thaks.
Thanks for this. I went for a eye exam for the first time in years last week and was somewhat railroaded into Neurolens (though they did not tell me the names of the lenses I was buying at the time). It wasn't until I got home and the dilation drops cleared that I was able to do more research that I realized the screening form, the measurement device, and the lenses were linked. The doctor didn't discuss alternatives or mention what a prism lens was, and since I haven't required glasses in the past, I did not know enough about prescriptions to question them essentially saying "You need these $1000 lenses for your condition, they're the only thing that will help." I also couldn't read the features comparisons they were showing me with the dilation drops in, or look up alternatives or extra info. They're already ordered, so I guess I'll think on it a bit, maybe try them out, and keep a close eye on the warranty period.
How are the neurolenses? Worth it so far?
I’m in my try out period for neurolens and I’m going to get my money back. I’ve fallen and can’t function in them. I’m so glad to see your video. I wish my doctor was as experimented as you.
I didn’t know you could get your money back
Your experience is very different from what I heard from other people trying it! I wonder why!
@@stevec9669 I wish I knew why too. I had my hope invested in them.
@@stevec9669 Some of the errors it makes are predictable. It works better for certain types of cases than others. So some people will see improvements, and many will not. Highly advise instead finding a doc who is very knowledgeable and skilled with prism and ensuring the glasses are accurately made.
Really like your equipment in the background 😊
I have been prescribed prism lenses and they have changed them 3 times in less than 2 years and I haven’t had any relief whatsoever I wish you were my doctor
Go with neurolens if you can afford it. Machine can perform better and more consistent than great majority of doctors.
Thanks for your review.
Machine measurement.
My eye doctors over the years when measuring and prescribing lenses have never taken into account my daily activities or side to side movement of my head. Every machine and instruction has been to hold my head in a fixed position with as little movement as possible during measurements. The interaction between the inner ear and eyes has never been mentioned or discussed.
great video, thanks. so Nueralenz is type of machine the eye dr. uses, Not a type of lens for my actual glasses? do i have that right? i have advanced glaucoma, and have lost about 60-70% of my vision. right optic nerve damaged. my glasses from Americas Best, & Kaiser dont work all that well, vision is still blurry. would the Neuralenz measuring process help me? theres an eye dr. near my house, that has Neuralenz.
Dr.. thanks for the video. Would you have tested contoured prism lens like Neurolens? I seem to be a perfect match for trigeminal dysphoria with symptoms like dry eye eyes, eye strain, headaches, neck pain etc. wanted your opinion of prism lens have helped anyone with this case.
Contoured prism just means there is more prism at near than distance. So yes, part of my exam is always checking what prism works best at distance and what works best at near.
You can also decenter bifocal lenses to achieve different prism at distance and at near.
It’s as though all our eye care professionals have forgotten first year physics and basic optics.
Using different prism at near and distance is often beneficial. Depending on what a person does in their life, you’re often much better off with glasses specifically designed for computer work that include the best functioning prism.
It’s not that their lenses don’t help some people. My objection is to the marketing hype and approach
@@opto-mization Thank you for your response Dr. Add to it, i dont live in the US, so the cost of travel+stay+nerulens can run into a few thousand dollars. We have pretty good Ophthalmologists and Optometrists here. Will copy your feedback and reach out to a local Doc who might be able to help.
@@opto-mization In your experience has adding prisms for computer work been of any help for people symptoms that I mentioned of dry eyes and trigemenal headaches?
I have gone to eye specialists at very well known hospitals. Are there questions I could ask (either in appointment or before) which would help gauge if doctor's will perform tests like this.
I'm engineering minded and have been to many specialists in well known hospitals. Even after constantly talking about computer work, only one optomotrist actually put a paper close by to measure the correct lens, everyone else just added a formula. I've never seen anything that even hinted at the inner ear vestibular system
Ask them to text fixation disparity as well as VOR gain with various prisms. Then ensure the lenses are made to account for this.
@@opto-mization Thanks I appreciate that. Is it possible for large (-2.75) sphere settings to have non-uniform prism affects throughout the lenses. I find that even small changes in where my glasses sit on my face can affect my eye strain a lot. Are there variations in who grinds the glasses which can help make them more uniform across the lense?
As an aside, those keywords were very helpful. I have strabismus I have controlled well since childhood (from very different left vs right prescriptions) and have a very strong prism fusion range test (although I think only tested for distance). But I always talk about eye strain and I don't think any of the wikipedia fixation disparity tests were ever performed 😞
Is this product useful for helping with irregular astigmatism caused by lasik?
No. It doesn’t change anything to do with irregular astigmatism.
That said, I’ve seen a lot of Binocular vision dysfunction post-lasik. I believe it was often underlying beforehand, then seems to be exacerbated by the person now viewing the world differently and their visual system not able to re-calibrate around the changes.
It’s worth checking with a vision therapy or neuro-optometrist experienced in BVD. Some of the symptoms that are often attributed to irregular astigmatism may be also made worse by BVD.
If it truly is irregular astigmatism as the entire cause. Then often a scleral contact lens is your best bet.
@@opto-mization Thank you for pointing me in a direction I had not heard of before. I do have some but not all the symptoms of BVD so I have to look into that since I may pursing a solution to the wrong problem. Thanks
How do you find an optometrist who specializes in prism?
do you know any doctors i could go to for this fitting?
Find an optometrist in your area with experience treating binocular vision dysfunction with prism /micro prism. COVD.org is a good place to start but call the offices first and ask!
As a 60 year eyeglass wearer, I've found myself closing one eye when I concentrate. I know astigmatism is an issue, but it seems like after reaching 60 years old, I do it more. I've never had a doctor prescribe prisms, and am wondering if Neurolenses or prisms could help with this?
Closing one eye when concentrating is almost certainly a sign that you’re having trouble using the two of them together.
Rather than the Neurolens approach, find an optometrist who can skillfully measure how your eyes work together and prescribe prism and or vision therapy to improve this.
Thank you! I know that another complication is that my PD is 30.0 in my right eye and 35.5 in the left.@@opto-mization
Hello. I just googled the Neurolens for an eye strain and headache from pc problem. You didn't say anything about this so I'm not sure if I'm at the right video. But if I am, is there a clinics in Japan that make those?
You’re better off both financially and symptom reduction to find an optometrist who is very skilled at prescribing the right lenses with prism for use at your PC. The neurolens will help you more than doing nothing, or than a regular prescription, but not as much as something that takes into account your accommodation and binocular systems and the complex interplay between the two.
Is this going to solve my problem? I have a terrible astigmatism on my left eye. My right eye has astigmatism too, but not so terrible at all. I don't have lazy eyes, misalignment eyes, headaches, and dry eye. However, I sometimes feel dizzy and eye strain when I works on the computer for 6-7 hours.
The dizziness and strain is usually caused by a form of binocular vision dysfunction. It doesn’t show up as a classical misalignment issue. Ensure the doc is very well versed in this problem will make a huge difference l. You should be able to work without dizziness and eye strain
@@opto-mization But does it also solve the problem of my astigmatism? My glasses with regular prescriptions are alright. It doesn't solve my left eye with awful astigmatism.
Your eye muscles need rest and cannot be expected to function optimally for six or seven hours without taking frequent breaks. What if you hold a 25 pound weight in your hand for 6 to 7 hours? Wouldn’t your arm fatigue and feel strained?
You’re the store I came to you are the doctor what about reviews on you? Does it exist?
Richie I’m not sure I quite understand your comment.
So you do or do not have experience prescribing neurolens?
I do not use it with my patients. Many come to me having purchased it, so I have a lot of experience with their lenses and approach.
For most of those patients the neurolens has been better than just a ‘standard’ prescription. But in an effort to produce a patentable piece of technology, it makes too many sacrifices.
If it’s your only option over just a ‘regular’ prescription then it would be worth trying.
If you can find a doc who really understands how prism impacts your depth and spatial perception, and how to manipulate and order lenses to account for this, you are better off.
Every patient I’ve had who has experienced both reports more improvement (for less$$).
Neuorlens I went and got tested for Neuorlens. I don’t have a reason to buy them. I was curious. i’m going to stay with old Glasses
This is great news but, how do you find doctors near you that are just as passionate about helping people?
I wish I had an easy answer for you.
My best recommendation is find someone with a satisfaction guarantee on their recommendations and a history in vision therapy and functional lens prescribing.
So... How do you find a legit optometrist who is skilled enough to prescribe prism lenses? Is there a professional association or registry of some sort to find someone near me?
Hi Griffin,
Find an optometrist who has a lot of experience with vision therapy and often a clinic dedicated to it. Call their office. Ask if they prescribe prism and ask if they consider visual-vestibular integration when they do. COVD.org can be a good place to start.
We call it ‘ergoptics’ or ergonomic optics, some call it functional prescribing, there are a few different names.
Also ask about policies regarding glasses returns and redos. You want to work somewhere that can redo the glasses if the first prescription doesn‘t work as intended or will refund you if they can’t make it truly beneficial.
Our ebook describes a fair bit www.opto-mization.com/ebook. Although I do understand the irony of recommending a book when people are struggling visually 🤦♂️. Currently working on an audio version!
@@opto-mization Thanks so much!! The video and this comment were so helpful.
I have the feeling this doctor is not a Neuolens provider; if he were, he'd be singing a different tune.
You're completely right, although the order may be reversed. I am not a neurolens doc for these reasons. I can see the value it can provide, I just believe we can do better.
