I've been reading a lot of positive (anecdotal) experiences about the Neurolenses on Reddit and such. They can correct vertical heterophoria as well. I've read they take up to a few weeks to get used to.
They seem to help a lot of people. I really hope it's you! Because they are prism, I read they can make the "floor" look weird at first, almost like you're moving up/down when you are not.
Hoping they work well for you!
Just to add my experience -
I tried Neurolens for about 3 months. The first 2 weeks were rough, they were uncomfortable to wear and made my eyes feel slightly water-y. I did get used to them, and they were totally comfortable to wear about 3 weeks in. They helped with my general eye strain, but I didn't notice any improvement with flicker. I noticed that my eyes were less tired at the end of the day, but nothing super dramatic. I'd definitely recommend trying them if your doctor says you're a candidate though.
He diagnosed exophoria.
Here is my Neurolens reading:
Neurolens value: 1.4 BI [base in] (0.75 each eye)
They wouldn’t give me the readout to keep but the picture they showed me indicated that I look far beyond the content I’m looking at, especially while doing close work. When I asked him about this he agreed with my saying “convergence excess” (Edit: This doesn’t make sense, see my next post)
I would appreciate your thoughts on this.
This seems like a couple of different problems.
Edit: See my next post in this thread for additional information on whether I have convergence insufficiency vs excess.
I don’t understand how I could have convergence excess based on the diagram I was shown. I thought looking past the image like I saw is convergence insufficiency. I really wish I had a print out of my Neurolens reading to refer to.
Maybe there was a miscommunication and I have insufficiency. I will call and sort it out tomorrow.
The Neurolens screen said “EXO” as well, I remember. I think I can be confident that the Neurolens technology itself at least diagnosed exophoria.
I am unsure about convergence now as diagram is showed me was seems consistent with convergence insufficiency, not excess as he said.
degen You don't have convergence excess based on the Neurolens reading, probably there was a miscommunication. Looking too far is exophoria / convergence insufficiency. I've been hearing from many folks on Reddit that these were a huge help, hoping it works well for you.
Your prism prescription isn't that large, but according to Neurolens, the amount of prism correction required is not correlated with the severity of the symptoms.
Came across this interesting video on Machine Learning and Optometry which talks about Neurolens. At around 50:55, note that they recommend larger frame sizes for Neurolens, with larger frame sizes being more effective. Something to keep in mind if anyone is trying these glasses.
I watched another video on Women in Optometry about the Neurolens. At around 54:15, we see that they are unfortunately not available for convergence excess 
-- since every Neurolens prescription is "more base in at near".
I've had Neurolens glasses for almost a year now. They've helped adequately. My eye doctor also has an eye therapy program that's an alternative to the glasses. I wonder if anybody has done that therapy program?
Before the glasses my symptoms were eye strain/pain, dry eyes, baggy eyes, neck and shoulder pain. The glasses have brought them symptoms down to a 1 or 0. I'm glad people are able to see past their marketing and how new they are to the market, but I've seen great improvements with the glasses. And the "contoured" part is really nice to have, as I can focus better on close, medium, and distance things depending on where I look through the lenses, further reducing strain.
plymn10 Curious what are your Neurolens measurements? Did they give you a diagnosis (convergence insufficiency)?
Glad to hear you've found some relief. We know a few people tried Neurolens on here and it unfortunately didn't help them that much -- I will visit an OD tomorrow to see if I am a candidate for them.
Got tested today. I am not sure I trust the Neurolens device; it was a 2 minute test and told me I needed BI prism (this is <1 DP in each eye).
My previous vision therapy I had divergence issues (and still do), which typically a BO prism is prescribed. It seems the Neurolens overprescribes BI prism.
I am going to try them out anyway since it's a money-back guarantee. They did give me a trial lens which did seem to relax my eyes a bit, so that's worth something.
Got it emailed to me. If anybody is curious. Is there anything I forgot to include here?
I'll add that I wasn't told I have BVD. But rather, my BVD symptoms occurred as a result of trigeminal dysphoria. After about 6 months of wearing the lenses, I got retested and my misalignment had drastically improved. My symptoms of BVD are always the least present in the mornings, but ramp up during the day (unless wearing the glasses). I found this curious. I can't help but wonder if Neurolens treats the problem/prevents the symptom rather than just treating the symptom.
Found a great post on binocular vision dysfunction: https://helloamh.com/binocular-vision-dysfunction-vertical-heterophoria-and-prism-glasses/
Note for this person, they prism glasses AND neck chiropractic care: https://www.healio.com/news/optometry/20150514/j722_2005_12_news_print_2
Dr. Debby suspected an underlying neck condition and urged me to have my neck checked. I met a chiropractor who specialized in the upper neck, who confirmed I had a severe neck misalignment. A month after being under chiropractic care and having my neck back in proper alignment, my eyes were reevaluated. It was determined that my vertical misalignment had resolved and all I had left was the smallest amount of horizontal misalignment possible. There was a direct correlation between the misalignment of my neck and the misalignment of my eyes.
There's also a Facebook group for BVD here.
Just got the Neurolens. I've worn them for a few hours, and they seem to be making things worse on a good setup. I guess I need some more time to adjust to them.
I have used Neurolens for over a month. It's not working.
I now have strong medial rectus pain which is not getting better. I can't look at anything close without triggering this pain. A very bad situation. I don't believe that Neurolens is the cause, as I was pushing through work, but it certainly didn't prevent this serious setback in my vision.
I still believe I have BVD, but Neurolens is not my cure.
