Q & A

Any questions?

We have collected some of the most important questions below.

When using our APP “Sweet Spot Analyzer™” you simply use our “Help” button when your picture has been taking. We will analyze the picture for you, or tell you what to do different.

Q: Our client does not have her old glasses. Can we use the new frame we found?
A: The reason for using the old frame is because of the horizontal prism in the near area, the reading power, and the anti-reflective coating. If the reading power is below +2,00D you can use the new frame without prescription lenses, but it´s better to use a pair of standard glasses close to the reading power. If the reading power is more than +2,00 D you must always use a pair of standard glasses with anti-reflective coating.

Q: The tool recommends corridor 15. What does that mean?
A: Corridor lengths should not be confused with manufacturers “minimum fitting height” that are usually  2-3 mm more. Ask your lens supplier for the corridor lengths for their type of lenses.

Q: Should we measure the convergence?
A: There is no need to measure the convergence. The Sweet Spot Analyzer™ will do the job for you. With Sweet Spot Analyzer™ we take a picture of the exact location of the pupils when reading. It cannot be done more precisely. The scale will tell you the exact pupillary distance.

Q: The picture shows a different corridor length on the two eyes. Should I select a different corridor length?
A: The short answer is no. The picture will just tell you the client has a different fitting height, or the frame is not in line, so you should adjust the frame to be in line, and take notice of the fitting height when you are measuring this carefully.

Q: My Visioffice tells me a different pupillary distance. What should I do?
A: Very simple. Ignore it, and count on the Sweet Spot Analyzer™, but you can keep on measure angles, fitting height and others with these kind of tools.

Q: Sometimes it is difficult to see the pupils on the picture. How can I optimise this?
A: Please note, the iPad Pro are much better than other iPads. You must take the picture in better light. Please try to find another place in the room with better light. Daylight is optimal. The iPad PRO is the only iPad´s to use. Your client can have very dark eyes, so you can use the edge of the iris as guideline as well. You can ask your client to open their eyes at the same time.

Q: My client has mono vision. Should I take this in to consideration when ordering the lenses?
A: The Sweet Spot Analyzer™ is great for these situations. If you use lenses with default values, like a 2.5 mm addition insert, you should do nothing different, but if you order your lenses with 0 mm addition insert then you must order a different PD. Simply remove 2.5 mm from the result.

Q: I have a few questions about my picture. What should I do?
A: Please use our “Help” button in the app, and e-mail the picture to us. We are here to help and will do so as fast as possible. This service is free of charge as long as you subscribe to our app.
