Predictive PAL Tolerance via Fusional Vergence (Method for Determining Acceptance of Progressive Addition Lenses (PALs), Tech ID: 11‑054)
Technology Overview: A clinical decision method that measures at least one fusional‑vergence parameter for a patient and compares it to a threshold to predict the probability of PAL acceptance before dispensing—reducing returns and improving patient outcomes.
Industry Pain Point: PAL adoption can be hindered by non‑tolerance due to binocular vision characteristics; trial‑and‑error fittings create costly remakes and poor patient experience.
NJIT Solution: Use objective fusional‑vergence metrics and a threshold‑based acceptance model to inform lens selection and counsel patients early in the workflow.
Key Features & Advantages
- Quantitative predictor of PAL acceptance prior to dispense.
- Integrates with standard optometric testing (binocular/stereoscopic vision).
- Potential to lower remake rates and enhance patient satisfaction.
Development Stage: TRL 4–5 – Clinical/optometric method with issued patent embodiments; international family validated.
Target Markets
- Ophthalmic lens manufacturers & retailers
- Optometry clinics and vision science groups
- Practice‑management software & diagnostic device vendors
