“Artificial intelligence in lens design
The Varilux XR design leverages the power of artificial intelligence in order to take patient behavior into account. In an exam, the patient is given a handheld device and asked to perform multiple realistic visual tasks. After more than 1 million data points are created, they are used to make a patient’s “digital twin,” which is used to predict visual behavior and eye movements, which is ultimately factored into the lens design.
Predictive modeling takes into account the following:
• Visual acuity loss
• Postural efforts
• Head movements
• Hand-eye coordination
• Gaze behavior
If you have a measuring device today that is handheld, that really understands the way the individual's eyes are moving right and left and up and down and the way they focus and the way that the person holds a device, you have exponentially more data points to develop a lens that is truly customized based on both the prescription and behavior.
Progressives have gotten better because they've been able to predict the person using them better. What I like about the Varilux XR lens is that if you were to take all the learnings of progressive lenses and you create a product that is going to allow for the best outcome through the knowledge and AI and all of the millions of data points that has been collected over time on users, then you can create progressive lenses that are more intelligent and more customized for each, individual patient.”
