OptoExpert: AI Lens Measure is a professional optometry measurement app that uses AI‑assisted pin placement to capture all the data needed for a glasses order directly from a photo of the patient wearing the frames. The tool automatically detects facial landmarks, calculates pupillary distance, fitting height, progressive lens parameters, and more, delivering results in seconds. Download OptoExpert: AI Lens Measure APK Free lets optical professionals start measuring with any Android device.
## OptoExpert: AI Lens Measure APK Features
The latest version of the OptoExpert: AI Lens Measure APK for Android provides on‑device processing, so no image data leaves the phone, ensuring privacy while delivering fast results. Below are the core capabilities that make it a digital AI pupilometer for eye‑exam measurements.
The AI detects face landmarks and positions measurement pins automatically, allowing you to drag them for fine‑tuning when needed.
All calculations run locally, meaning the app works offline and no data is transmitted to external servers.
You can calibrate with a known lens width or let the AI estimate the edges, which speeds up every exam.
The app measures pupillary distance (monocular left & right), bridge width (DBL), lens width (A measurement), lens height (B measurement), minimum blank size, pupil‑to‑bottom‑of‑lens, pupil‑to‑bridge‑center, and effective diameter (ED).
It also captures vertex distance, pantoscopic tilt, and frame‑wrap/inclination angle for progressive lenses.
The interface walks you through each step, reducing manual effort and minimizing errors.
Results can be saved and shared with laboratories directly from the app.
The free trial includes the first two eye exams; unlimited measurements are available for $4.99 /month.
These features combine to create a professional optometry tool APK that rivals costly iPad‑based systems from Essilor and Zeiss, which charge $50–100

impossible to measure or understand instructions. tried 3 times then asked for money. uselss. do a demo of how to use. rubbish. shpuld be 0 stars
app really sucks
not worth money to provide pupillary distance when even if i pay i might not get pupillary distance
Designed to fail to force you to purchase. wont let you edit your adjustments if you accidentally press next. 2 free attempts max which have to be done perfectly and also didn't clearly state to have glasses on.
If this app is not user friendly
2 tries and locks you out. instructions not clear to start.
excellent
It did the job.
I created an exam, didn't finish it, deleted it and when I tried creating a new one it says I can't because I already did one free exam.
just kept on saying cannot load case
Easy to you and effectively well
it was easy and quick with good prompts
useless
it helps a lot to find what you need
this leaves the measurements up to me ! I wouldn't have downloaded the app if I could do it myself
Doesn't work
junk
simple and accurate 👌
tried ones and seems very nice
complete trash, according to this my pd is 0...
very easy to use and helpful
it's suck doesn't allow you to try it out.
works well
sucks
I would give it 0 stars if I could I didn't know about the limited thing and u have no money make it have a few more free tries
sucks
It wouldn't give me the opportunity to redo it
horribly inaccurate. resulted in my whole family having to get our glasses redone. screw this app
good
dont bother
very limited
inaccurate and stops after one try
couldn't understand it
difficult
confusing
confusing as all Hell.
best app
I attempted to use without realising I needed my glasses on. Realised, and then went and got my glasses to try again only to be told my "free use" was up and now I had to pay. Not happy!
how can I read the measurements on the inside of my glasses if I'm wearing them?!?
bad
easy to use, l struggle with technology this is great
couldn't get it to work
They don't tell you lenses are required and if you're just trying to get your pupillary distance measurements so you can order glasses online, it's not possible.
Doesn't work, no successful measurements, doesn't let me try anymore, can't clear app data.
did not provide needed measurement, not user friendly
says 10 free. I got 1 for sure , maybe 2.
does not work
The UX really needs some work. I got my photo into the app and started doing the eye pin placement after watching the tutorial movie. Then went onto bridge pin placement, so I went back to the tutorial movie again, watched the part I'd watched previously and either missed the part about where to place bridge pins, or it wasn't there. I then decided to guess as to where to place the bridge pins, but unlike the eye pins screen, the tick button was not there after I'd placed the 1st pin. I gave up
won't measure anything!
you can only use it once for free.
you need to subscribe in order to use it
It wasn't able to measure my PD.
useless app...
If your glasses aren't printed with the information it wants, the app is useless. it won't let me try with another pair of glasses without paying.
Overly complicated.
good
Doesn't do what it says
pupil distance 93mm actual about 65mm
Terrible waste of time
It measures glasses, not eyes.
this app is bs! it says you only need the #s on the arm of your frames & to take a selfie but refuses to give you your pupillary distance bc it wants A LOT MORE INFO that most people don't have. it should be illegal for eye dr offices to withhold pertinent info for patients to get glasses if the patient wants to purchase frames elsewhere. creates a nightmare for poor people! this app contributes!
No results given, all results N/A
All I wanted to do was measure pupil distance, not do extra stuff.
Doesn't work
took a couple of tries and then all of a sudden it stopped working wanted me to subscribe never even finished
useless
Useless and stressful. Just wanted to find my PD. Gave up
Why do I need to sign up and give my info for simple task?
Needed 2 PD numbers. Good app but could not accomplish what I wanted.
useless and inaccurate
This app does not make it clear that you should have your glasses on when you take the photo. It also is assuming that your current glasses fit properly and that is not always the case. useless if they do not fit properly.
doesn't save measurements
good app, but after making two mistakes and deleting exams, I can't proceed unless I buy premium version. disappointed
terrible app....it doesn't say its only good for one exam. If you back out to see which of the 3 numbers on your glasses is the bridge distance...it takes it as an exam and you have to register to do it a second time. not recommended.
garbage app. once you figure out what to do you run out of trial exams
waste of time
advertised as free, but you only get very limited attempts, then a subscription is required
The app is not intuitive and fails to provide necessary instructions on the screen.
I only want to know pupillary distance. To do that you need to do 2 exams, to take 2 exams you need to subscribe and pay.
Excellent
stupid
puple distance was completely wrong.
Frustrating. I followed all the directions and used the hints and received a very inaccurate PD measurement. It gave me the measurement common on a child. When I tried to start over, it told me I had no more free tries left. I'm not gonna pay money only to receive another bad reading!
didn't show anything
very manual
useless
didn't work for pd
Not very user friendly and by the time you figure it out you cannot load another picture because your one time use is over.
Doesn't seem to be user-friendly so far
Too difficult to measure. The IPD is almost impossible to measure it.
Inútil
doesnt work don't bother
wouldn't load anything after taking photos. Then it said I have no more free exams left. Not user friendly
garbage
just want to measure ipd. why do I need existing glasses details to do that? I don't currently have glasses. pointless app.
the measurement tool doesn't measure anything.
frustrating and broken
bad
I could end the task. Your app didn't show any result.
Did not work, tried several times then it locked me out.
Used four years ago and worked fine. Now won't even open (opens and immediately closes/crashes). Tried forcing the app to stop and restarting/ closing down phone, etc. Will uninstall and choose a more reliable app.
Failed to read camera picture. Counted it as two exams. Unable to take more exams for the day, even though the previous ones were not completed/done.
Confusing, don't waste your time. It wanted numbers from a glasses frame that weren't present and no way to continue.
Doesn't seem to recognize that I took a photo through the app and when I take a photo outside the app and upload it into the app it doesn't seem to recognize that either. There's no way to go forward from that stage.
This app is so easy and precise. It helped me get the correct measurements for each frame I was considering. I was able to order glasses online and know that they will be perfect.
It works! Give me the exact same result as one eye doctor. The second eye doctor was totally different but that was at Sam's Club so I don't know the first one was in America's best.
By the time I figured out how to use the app, I had exhausted my two free tries. Subsequently, the app turned out to useless for me, plus, a complete waste of my time.
This works great now. No more credit card sizing. It now sizes based on the glasses you are already wearing and the size printed on the glasses. The instructions and tutorials were easy to follow. I do understand the bad reviews, as i have attempted to use apps that work that way, but this app no longer does, as of the time I'm writing this.
superb and excellent APP for all over opticians. this app are need to every professional opticians . this app are excellent work for progressive and other lenses fitting measurement. if every optician install this app in our mobile than nothing to require other app for progressive measurement. I am fully satisfied this app. Thanks
The instructions are a little difficult to follow, even with the video tutorials. I attribute this largely to unintuitive navigation decisions in the interface. That said, once you figure out how to use it, it's very accurate. Four out of five stars because the measurement accuracy outweighs the learning curve.
I didn't know the number of attempts to measure was limited. I did it wrong a couple times and restarted and then never got to finish the measurements.
Wasted my time. Tried twice. Gave it permission, pressed camera option, took photo. Then went to exam tab and couldn't see the photo. Deleted to start again and it wanted cash for unlimited exams when it had done nothing useful at all. Needs a lot of work to be more user friendly, despite the replies to previous reviews from others claiming the interface is good. Uninstalled.
Couldn't figure it out & it used all my "free exams". This app is frustrating & doesn't seem very fair to have so little instructions to where you have to use up your "exams" just to try to figure it out.
App says you get 9 free measurements. It counts any that you start, screw up and delete. It counts every single time you click the "create" button. Weather you make a measurement profile or not. By the time I had a friend available to take my photo, all 9 were used. Even though I'd only filled out one.
I installed it to have my PD. It gives me 10 mm less than my real PD. Developer says the app is made to perform eye exams for a glass frame but I have to enter all the info of the frame I'm using but no new info appears after the exam. The app info detailed doesn't agree with the the one given when an user complains. It seems it is made to have YouTube views only.
I am dispensing optician and use that kind of measurement everyday. I use Rodenstock equipment, but wanted to find something for mobile phone. Somethimg like Hoyas tool, bit without the frame. I have made similar measurements with camera and some picture software measurements. So I measured myself with a frame and it showed 62.9mm PD And mine is 68-69, depending on the other measurements. I think the premium plan is overpriced.
What a waste of time, the video tutorials don't match up to what the app is asking for. I have worked in multimedia software development for 20 years and there is nothing intuitive about this app. It makes no sense... I don't know what its asking for, idont know where it wants me to put the measurement points. There is a random image of a credit card, like thats supposed to make sense? Reallt not clear how to submit points. When i input points it doesn't do anything.
Seems useful but my glasses didn't have the mandatory eye size so... Couldn't use the app
It's a great way to get accurate info for ordering frames online with a sense of security knowing your frames will fit.
Would need 2 other apps to use this one. I dont wear glasses, I just need to ensure my eyes are no more than 68 on the distance to be able to use a VR headset. This app cannot do the one thing it says it does without someone knowin their eye size and bridge size that says is on my glasses I don't wear. Not for those of us looking for an app that needs you to be wearing glasses. Wouldn't the first person to need glasses first need to know their IPD before they can get glasses and to use this?
This app requires you to upload a photo of yourself then a photo ID and a credit card, they claim the ID and credit card is for the distance measurement reference for the algorithm. Of course they really just want your ID and credit card information. Stay Away.
Good app. I was struggling to get my pd calculation correct to be able to order some new glasses but this app made it so easy and accurate too.
Getting results still requires having prescription glasses, despite responses to the older reviews saying the app was "redesigned" and therefore isn't an issue anymore. I need to have a pupillary distance measurement BEFORE I can purchase my first pair of glasses 🙃
GREAT!! I've never needed to get a PD measurement in my life. Once I downloaded this app and give it a try it was simple, fast, and accurate the best of all it was free! But just so you know, if you zoom in on your picture to place your pins more accurately. And not one ad!
Confusing. Difficult. Not your fault but the numbers on my old frames wore off and are not legible.
Great optometry eye distance app. Very good and easy to use.
Very good app, for eye measure calculations. It was very easy to use and I like it.
Its great eye measure app for me. Its very easy and helpful for me. We can save every exam. Great job
Very nice app for optometrist , easy to use with great user friendly interface
Let's you take an eye exam conveniently at home and gives accurate results. An extremely helpful app.
Great app for eye measure. Very helpful for eye shop owners, as often they need to measure eye sizes. The UI is very user friendly and easy to use.
Worked fine for me. YOU MUST BE WEARING A PAIR OF GLASSES AND KNOW THE GLASSES MEASUREMENTS. I wear glasses and had all the required measurements to input. You get 10 free measurements, then I guess you have to pay a fee. This will probably be the only time I needed to use it, so I have 9 left.
So nice app to measure the eye ability is very simple and easy to use
An effective tool, the application system is comprehensive and regular, the interfaces are excellent, I like it
nice app for eye exam and eye distance measurements, easy to use
Rubbish. Doesn't ask for unnecessary permissions (like mic, files etc) which is good, but cant get past first screen of "new eye exam" because of an insistence to set lens width. There is NO OPTION to set lens width. I dont even wear glasses, just wanted an IPD measurement.
Cumbersome to use and inaccurate. It won't let you enter measurements that you already know you have.
Great! I can measure my eye distance without putting a ruler between my eyes
Followed directions exactly and it says my pupil distance is not available. I can download one that actually works faster then I can figure out what the problem with this app is so plus I put the pin to the farthest left side of my left lens like it says to and it keeps telling me to put the pin in the right spot. Horrible UI Yeah buy!
Can't figure this thing it out. All I want is ipd distance and you have to set it up like you have glasses. Completely useless if you don't have glasses.
I like the idea, however I've never been able to get an accurate PD measurement with the app. Results 3 to 6mm wrongs unfortunately. I tried several times with a frame with lenses and without.
It's asking me questions that I'm trying to get from the website themselves... I don't know eye size and we don't have a pair of glasses to go off of.. if I did I wouldn't need this app lol.. makes no since
Completely inaccurate. You have to measure with glasses on and the app doesnt account for lens distortion. Don't bother with it if you need and accurate PD.
The app should have real directions instead of "drop the pin" not impressed
Ok, like, my glasses are old, so the codes have warn off. Without those codes, it does nothing.
Couldn't start without lense width and doesn't give the option to enter
Trash. Doesn't perform simple calculations (i.e. PD measurement) and awful tutorial.
You guys no confirm button. Everytime I try to place the marker it keeps resetting.
Doesnt let me measure pd even the measure at bottom does nothong. Missleading or stupidly difficult app.
Not helpful at all. Should not need frame size to measure pupils!
Optometry eye measure is a best app for eye solution. Easy to use and user friendly interface.
Has potential, but fails to do its job. The app will run and let you do all of your measurements based on a photo of your face. Unfortunately, those measurements don't register and the results return as N/A. You'll do yourself a favor if you just measure your pupillary distance with a ruler instead of wasting time with this app.
The app isn't free. I didn't need a full eye exam. I just needed a few measurements. The app is misleading.
Many bad reviews but it takes time to sort out how the app works. I feel I received a very accurate PD value
Doesn't work. Doesn't display measurement results after placing pointers on pupils. Just displays n/a.
Very unclear instructions, got one unrealistic pd and did again but it would not give me a number
Wow.. very well made app the ui is smooth and beautiful. Tested with one of my lens to test the eye exam, results seems to be accurate i guess.. thanks
Optometry eye is the best app of play store. I love it. Thanks developer. 💕
Eye test app that works like a charm, its pretty fantastic, i really like the way its built and interface is super nice too!
This app have a nice and clean user interface, guides you towards the eye measurement, eyemeasure. Really good for eye-exam.
Seems like a pretty accurate app for measuring things like pupillary distance. I used it in conjunction with my reading glasses, the measurements printed on the frames and in app photo I took of myself. It isn't clear to me if the pupillary distance is the reading pupillary distance or normal/long distance. I suspect that it is the former due to the fact I held my phone at arms length for the photo. I've read there is about a 3 mm difference between the two pupillary distance measurements.
Amazing and superb application for people who want to check there eyes weakness .. this application is good for test
Best app for eye distance measuring! It has nice graphics and is also so easy to use. I will totally recommend this.
Does not work. The dropped pinsrandomly move so they measure ransom things
Neat app for eye distance measuring, definitely not a replacement for going to a Dr.
Perfect app for any Ophthalmology & Optometry specialist or student. Highly recommended.
Very useful app to perform Optometry eye measure, pupillary distance and eye-exam calculations.
Very nice and useful app for eye measure, eyemeasure , eye-exam , eye distance , Optometry . Perform optometry eye measure , pupillary distance and eye exam.
This app is really helpful for eye exam calculation. Easy to use, I've passed the test.
The easiest and best app for conducting eye exams at home in comfort. It works well and accurately gave an indication of the eyes.
Very nice and interesting concept. Perform Optometry eye measure, pupillary distance and eye-exam calculations. Design is very good and good part is easy to use and understand.
What others are saying. I entered all the info right and it gave me a 25mm pd. This doesn't even make sense for it being halved or anything, I know my pd is about 60mm just not the exact measure.
Great app for performing eye measurement related to glasses. Great work by developers.
Eye tester is a very good eye test optometry app I used this app and very interesting in my own eye test use. I like this app very much.
Best Optometry app. Good design, simple and easy to use. Recommended.
It measured my PD number as 25mm, which is wildly inaccurate. For reference the average adult is between 58-74mm. Won't be using this app again.
Unusable! Doesn't do anything except take you to a YouTube video. When you finish watching... that's it. Over. Waste of time.
Best app on performing optometry eye measure, or caculate pupillary distance. Highly recommended for professionals...
It measured my eye distance. Although, it took a long time because the the app is designed very poorly.
This is amazing! I had no idea such optometry apps existed. Professional and straightforward to use.
The best Optometry app, eye measure has never been this simple. Best UI, the app is superb, amazingly lite weight.
The app has a friendly and easy-to-use interface. It guides the user through the necessary steps for eye measurements related to glasses. I'm curious if this could be used as well to measure pupillary distance for VR headsets. Note, I couldn't get the camera function to work even though I gave the app the necessary permission.
Good app for measuring eye distance for eye exams to save time
Nice to have this app and check the health of the eyes any time you need. I passed the eye-test exam on here and got the results which helped me to understand what to do next. Good working app with easy concept and comfortable design.
Really good app. Nice graphics. Easy to use. I'd recommend to anyone.
Very useful app for eye measure and eye-exam calculations. Recommended.
Very useful app. Pros: - zoom feature for accuracy - ability to revisit a photo/exam - ability to customize meas. set.
How disappointed I was when I found out I had to pay money in order to unlock the apps full potential. 1 star :(
Not good. Requires glasses. I was looking for an app that can tell me what my ipd is for be usage but you need to be put glasses lens size in to run any of the tests.
