Product Spotlight: VisionFit

VisionFit is an innovative wearable system of lenses that is tunable, solid state, mobile and electronic.  This device can provide subjective sight examinations with increased ease for patients and optometrists. 


How Has Refraction Evolved?


Subjective refraction originally involved trial frames with trial lenses.  As time went on, manual and automated phoropters were developed to increase the speed of this process.  However, phoropters had their own disadvantages.  The VisionFit claims to bring subjective refraction back to the spirit of the trial frames approach.  It combines speed of operation with maximum freedom for the patient into one device. 


The VisionFit provides more flexibility for the patient to move around and interact with daily life activities while utilizing trial lenses.  The speed and accuracy are comparable to the automated phoropters that optometrists have been using for the last 20 years, but patients now have more freedom.  This becomes extremely handy for patients with special vision needs or with needs for multifocal prescriptions to move around with the trial prescription. 


The VisionFit has a few main features that make this product extremely intriguing for optometrists.  The wearable trial frame contains an electronically tunable adaptive lens stack set.  The adaptive lens consists of an adaptive spherical lens, adaptive cylindrical lens and an adaptive aberration lens. Then, the innovative aberration lens consists of a liquid lens consisting of four layers with 32 transparent actuators


How Are Doctors Receiving This New Technology?


Newer refraction technology is ultimately about delivering an easier, more convenient and more satisfactory refractive outcome to the patient than the traditional method. Some doctors have resisted using new technologies like VisionFit, but many doctors realize that advancements in technology do not replace their role. They have found that technology and new equipment can enhance the patient experience and time trying out prescriptions for all parties.


Doctors are still needed to review results from objective and subjective exams. They need to assess the suggested prescription changes and base that alongside the history of the patient.  Optometrists are still needed to evaluate the potential impact that a prescription change might cause and make a comprehensive decision on what prescription to write based on the refractions and their expertise.
