## What is Optical Dispensing Assistant 2?

Optical Dispensing Assistant 2 for the iPad takes your progressive lens measurements to a new level of accuracy. Measure your client's pupil positions in multiple postures (sitting, standing, reading) to find the most accurate monocular PDs. No longer will you have to rely on marking dots on lenses!

Not interested in those large, expensive measurement devices provided by the large laboratories? Then Optical Dispensing Assistant 2 is for you. It uses an iPad and NOTHING ELSE to provide hyper-accurate measurements. That's space and cost savings to your business. Not interested in having to buy an expensive iPad Pro? ODA 2 works with ANY iPad (although an iPad Pro is recommended).

You can also use Optical Dispensing Assistant 2 as an electronic mirror to aid clients in choosing their frames. Each job allows you to record multiple images using the iPad's camera.

Use it as a brilliant marketing tool so your client can email their friends to show them their great new glasses, or take a printed copy home to show family.

Using the gyroscope, accelerometer and LIDAR (if available) of the iPad to ensure accurate alignment, the iPad camera is used to take an image of the patient wearing the chosen frame. The touch-screen of the iPad is then used to mark the pupil and frame locations to provide the progressive lens height measurements. To measure monocular PDs, the iPad is held like a book and an image of the patient looking at near is used to determine individual eye convergence when reading. If your iPad has a LIDAR scanner (newer iPad Pro models), then this will be used to improve the accuracy of your measurements.

Pantoscopic tilt and vertex distance can also be measured using images taken from the side. Frame wrap can also be measured allowing you to have all the information you need for advanced progressive lenses.

Optical Dispensing Assistant uses specific knowledge of the iPad cameras to ensure near PDs are accurately calculated. All iPads (apart from the original iPad 1 without camera) are supported.

Forget dotting lenses and relying on positioning yourself correctly. The Optical Dispensing Assistant 2 ensures you have the iPad correctly positioned and aligned to maximise the accuracy of your progressive lens measurements.

Other features:
- Unlimited images can be taken for each job.
- Results from multiple images are combined to produce a single result.
- Near measurements allow more accurate determination of unequal monocular PDs.
- Final results are a combination of near and distance measurements (near measurements are used for inset, distance measurements for OC heights).
- Printing and emailing of job results.
- Automatic face and eye detection allows automatic zooming to the face when marking up.
- Zoom and scroll while marking tools are on screen.
- High-wrap frames supported.
- Ability to measure frames tilted from horizontal.

Subscriptions renew automatically, at an interval you select (one month, six months or yearly). Payment will be charged to your iTunes account immediately once you commit to the purchase, and will renew automatically at the end of each period. You will be charged 24 hours before the current subscription expires, unless you cancel before then by visiting your Account Settings.

### 1/5 — Mr

*2016-03-12*

I downloaded this app a week ago and have been using it in conjunction with my hand measurements and I have found a significant difference between both readings. The app seems to be very inaccurate and was hoping whether there was a way to overcome this issue. 
I would appreciate if the developers could shed some light on this.

## Frequently asked questions about Optical Dispensing Assistant 2

### What is Optical Dispensing Assistant 2 used for?

Optical Dispensing Assistant 2 is used by opticians to take precise progressive lens measurements for clients. It helps determine accurate pupil distances (PDs) in various postures and measures other crucial optical parameters like pantoscopic tilt and vertex distance.

### Does Optical Dispensing Assistant 2 require special hardware?

No, Optical Dispensing Assistant 2 primarily uses an iPad and its built-in camera and sensors. While an iPad Pro is recommended for optimal performance, the app works with any iPad model.

### How accurate are the measurements taken by Optical Dispensing Assistant 2?

The app leverages the iPad's gyroscope, accelerometer, and LIDAR (if available) for accurate alignment. It uses specific knowledge of iPad cameras to ensure near PDs are calculated precisely, combining results from multiple images for a single, accurate outcome.

### Can Optical Dispensing Assistant 2 help with frame selection?

Yes, the app can be used as an electronic mirror to help clients choose frames. You can record multiple images of the client wearing different frames, allowing them to visualize their choices.

### How does Optical Dispensing Assistant 2 compare to traditional methods?

This app eliminates the need for manual marking dots on lenses and the reliance on precise physical positioning. It automates and enhances the accuracy of measurements, offering a more efficient and precise workflow for dispensing progressive lenses.

### What devices does Optical Dispensing Assistant 2 support?

Optical Dispensing Assistant 2 is designed for iPads. All iPad models, except for the original iPad 1 without a camera, are supported.

## Version history (last 5 releases)

### 1.63 — 2025-01-13

I really like the new automatic view selection! I hope you do too.

New features in this version:
- If you have a Lidar scanner (iPad Pro 2 and up), then the app can automatically distinguish between a front, left or right side view, by using the distances of the different parts of the images from the iPad. For example, a left side view has the left side of the image far away, and the right side of the image is closer. The automatic view selection can be switched off in settings.
- Changed the buttons on the bottom toolbar so there is now a quick "take a front view" button and a quick "take a near view" button. The original menu button is the third from the right.

Bug fixes:
- Fixed a bug where the vertex distance was just using the default 40cm rather than the Lidar measured distance.
- Fixed a bug that caused a crash when importing a job created in version 1.61.
- Fixed bugs around recording the depth and depth location.

### 1.62 — 2024-10-12

- Bug fix for crash in app.

### 1.61 — 2024-10-10

- BUG FIX: Chosen depth point remembered instead of showing the last photo's depth point all the time.
- BUG FIX: Fixed depth not being captured sometimes.
- BUG FIX: Fixed onboarding not laying out correctly on smaller iPads.
- UPDATE: Removed the photo library button as its somewhat confusing to have photos that can't be marked up.
- NEW:  Swipe right on job list to remove unused images.
- NEW: Changed "Purge" to "Clean Up" and added option to remove all unused images that are from jobs more than 30 days old.
- BUG FIX: Fixed search to include frame description in the search.

### 1.60 — 2024-09-26

This version adds support for the LIDAR sensor in newer iPad Pro models. What does that mean? It means the iPad can itself measure how far away something is, meaning you no longer need to use the labels on side views to get an accurate vertex distance. It is also used on front and near view measurements to calculate distance. If you find your measurements are inaccurate with the LIDAR sensor, you can turn it off in the Information and Settings panel.

Also:
The layout lines have been moved on the camera screen for improved vertical measurement accuracy.
Removed the option to pay for the app "per measurement" as that created a sub-optimal experience when using the app.

### 1.53 — 2024-07-06

This version fixes a bug with restoring existing subscriptions to the same or another iPad.
