Predictive PAL Tolerance via Fusional Vergence

Case ID: 11-054

Description

Method for Determining Acceptance of Progressive Addition Lenses (PALs)

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
