Historically, technicians have had difficulty measuring spectacle lenses reliably, causing a lot of headaches for doctors and unsatisfied patients. The Visionix VX40 Fully Automatic Lensometer with wavefront technology greatly reduces this. Visionix wavefront technology enables doctors to have a full detailed analysis of a lens — over 1,000 points analyzed — at the push of a button.
With its innovative system of frame support, the VX40 is the only lensmeter on the market that combines automation with a high precision in measurement. This device helps doctors obtain existing prescriptions and detect errors in patients’ prescriptions that are causing poor vision, and complaints. The VX40 is also used in optical lab settings to optimize lens cutting precision.
Experience the Next-Generation Lens Analyzer
With the VX40, doctors can now show their patients the difference in lens designs instead of only explaining them. The VX40 features:
- Automatic lens type detection
- Automatic measurement
- Progressive lens analysis
- Comparison between progressive lenses
- Internal printer
- PD measurement
- Computer/network interface
- Measures both lenses automatically
Why Visionix Wavefront Technology?
Visionix wavefront technology is the next revolution in optics, providing unique benefits and exceptional accuracy. Visionix wavefront technology measures 1000 points, giving you a true picture of how the lens corrects your patient’s vision. Here are a few advantages of the VX40:
Ease of Use
The VX40 is fully automated, meaning that after you place the frame and press the “start” button, lens analysis and measurement are completely automatic — even left/right eye movement requires no user input! As a result, the VX40 allows you and your team to spend more time with your patients and less time struggling to neutralize lenses.
Automatic Lens Analysis
All types of lenses, including bifocal, progressive, freeform, and single vision lenses, are detected and analyzed by the VX40, which is compatible with virtually all lens technologies and brands.
Complete Visual Analysis
Progressive and freeform lenses no longer have to be a mystery to your technicians! The VX40 analyzes progressive and freeform lenses, then conveys the measurements in the form of a visual “topographic” map of the power across the lens.
Side-by-Side Analysis
With the VX40, the lens is studied completely, allowing you to pick any point on the lens to verify the power and accuracy of the manufacturing. Even freeform progressive lenses can be compared and analyzed, and you can show your patients the differences between different progressive lens designs.
