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.
