Hey! I thought I'd share my experience, and I have a few questions at the bottom for you guys who wear prisms :)

I'm diagnosed with ADHD and started meds 2 months ago. Since starting, I've been able to focus much better, and I'm no longer as irritable or hyperactive all the time. But, I noticed that when I'd stare at screens or focus on something for a long time, I'd get really bad eye strain and tension headaches. So I got my eyes tested. I have my eyes tested every 2 years and BVD never came up until now. All my life I've struggled with anxiety, derealisation, brain fog, blurred vision when standing. I just thought that was normal life. I also struggle with reading time to time, particularly with comprehending sentences, but I tied that to the ADHD.

I tried my prisms on today and WTF!!! It was quite overwhelming I wanted to cry. Everything felt in my face... clear!!! I can read screens without the words looking smudged. My eyes feel more open, and I don't have to squint to see. It kinda hurts to take them off? And everything looks dim without them on. It's like I can see colour for the first time. I keep moving them on and off my head to look for the difference. When I'm talking to people I can't stop touching and moving them. I've never had to wear glasses before, so it's an odd feeling for sure 🤣 But a good one!

My optometrist advised to just wear them when reading, as that's when I get the headaches and eye strain. Can I ask, how often do you wear your prisms? All day or just for certain activities? What about driving? Will I need to wear them forever? Sorry for the many questions haha. Thank you :)

I just can't believe it!! What the hellll 😭

the past two to three weeks I’ve had a constant off balance/swaying sensation, also at random times when mostly standing I have a sudden lightheaded dizzy spell and have to quickly grab onto something or sit down.

I also have neck pain, lower back pain, and pain down my left leg.
it also feels bruised under my left kneecap but there’s no visible bruising, it just hurts to press it.

Sometimes the random lightheaded dizzy spell is triggered by looking or leaning left. but not everytime.
sometimes it comes on randomly.

I have an e-consult with the GP next week to see what’s going on.

I just can’t work out whether this is coming from my eyes, inner ear, neck/posture, nerves, blood pressure, or something else.

has anyone experienced this?

Now I know I can’t go around driving with one eye closed but I made this observation today. With both eyes open, even with my prism glasses my nervous system must sense something is off. When I’m stopping I start to get butterflies in my stomach and then the muscles around my eyes feel like they are spasming. I’ve even had tachycardia out of nowhere when coming to a stop.

When I got my first set of prism glasses a couple months ago symptoms disappeared for a bit. Then they came back. I got a new set of prism glasses but I’m still having issues. I’ve been wearing them for a few weeks.

Should I tell my eye doctor what I discovered? Should I get new glasses? I’m doing vision therapy. I really struggle with jump duction.

Hello, I am looking for other people’s experiences with neurolens. My glasses came in today and I am wondering if it makes your vision “off” at first. I don’t even know how to describe what feels off. I guess the best description would be blurry/foggy. I can still see, something just feels off. Additional info: I have never worn glasses before. I got these to help with migraines and eye strain. (The eye doctor did a special test and said I have misalignment). Just wondering if this is an adjustment period or if they just are not working for me.

Hi all! I hope this post doesn't come across as too ignorant but I've had a few patients come into the opticians that I work at to ask about BVD and honestly it was the first I had heard about it! I'm in the UK and BVD here usually means Back Vertex Distance (this is included on all prescriptions here for RXs over +/-5.00D) and I was unable to find any information on Binocular Vision Dysfunction through the normal channels for eye conditions here (NHS, GOC, COO, even Eye Wiki!)

Looking further into it I read up some information about BVD and please do correct me if Im wrong but this is just strabismus, no? (Eyes not working together, issues with image fusion, notable different positions of the eyes resting) I'm curious how specialists in the US (That's where the most information on it I could find was from at least) test for this kind of thing and how the "micro prisms" work. We use the Maddox Rod Test in practice to test for less obvious strabismus and through our normal ordering channels we normally just request added prism onto a lens for no extra charge but I've never heard any of these be referred to as BVD?

My deepest apologies if I've just missed something very obvious but I'd love to know more :)

Hey guys! I'm looking for some help understanding the correlation between these 3.

I was diagnosed with ADHD this year and started meds 2 months ago. I always had trouble with reading, such as comprehending words on paper, but I thought this was just the ADHD. I would feel dizzy, foggy and anxious. Since starting meds, I've been using my laptop to do work. And I'd get super bad eye strain and tension headaches which I never got before. I went to the optometrist and they found I have BVD. I get prism glasses next week.

It's just bizarre to me that I've possibly been living with BVD my whole life without knowing. How is it that its only revealed itself since starting meds? Is it because my eyes focus better now? Also, did your anxiety improve at all since wearing glasses? Thank you!!

After years of vision therapy (VT) alone, I've recovered from my BVD (all 3 types of misalignments) almost completely, although not quite as "normal" as before the BVD. My only remaining symptom now is just a mild pulling sensation in or around my eyes, quite manageable but not completely gone.

I wonder if anyone with BVD here has managed to recover to their pre-BVD condition by whatever treatment route they used? Please share here as an encouragement to others.

BVD can lead me to have suicidal ideation. Can anyone relate to this? I'm quite behind on work. I don't know what to do. I need to read to do my work well. It's like the words go right through my head. I can feel myself being dissociated nearly all the time. I bought glasses with .5 prism diopter in each eye for relief, as that's what a provider suggested, but I can't tell if the glasses are helping. I wore them for about 10 days yet it felt worse to have them on.

I was prescribed 12-16 weeks of vision therapy with at-home practice. I'm about six weeks in, and I don't know if I'm seeing improvement or relief.

Test results:

My strabismus testing showed no measurable eye misalignment (0 prism diopters at both near and distance), but my fusional reserve was recorded as only −4Δ to +4Δ. So my eyes align normally at rest, but I apparently have limited ability to maintain fusion when the binocular system is challenged.

The diagnosis doesn't seem too clear, since everyone I speak to seems to have eye misalignment. So in my case I can't even try prism glasses.

Is vision therapy worth it in ny case? It's very expensive and long.

Visual accuity and eyesight is apparently perfect in every way other than the fusion range.

I also have extreme eye lid fatigue from the moment I wake up. Nothing helps except energy drinks for maybe an hour.

If a person is blind in one eye but has good vision in the other eye, and the functioning eye meets all of the Ministry of Transportation’s vision requirements for a regular Class G driver’s licence, is the person permitted to drive at night?
Would having vision in only one eye result in any restriction on nighttime driving, assuming the person meets all other Class G licensing requirements?
