Lens Thickness Calculator (3D) | Edge Profile Calculator
Free 3D lens thickness calculator for opticians, lab techs, and patients. Unlike static 2D calculators, OptiLens 3D calculates real-time 3D WebGL lens profiles factoring in true frame boxing (A, B, DBL), monocular PD, and vertical fitting height. Features 360° meridian edge scanning, Aspheric vs Spherical simulations, and instant multi-index material comparisons (1.50 to 1.74). 100% client-side and privacy-friendly.
Pace needs two or more snapshots. This launch has 1, so velocity and momentum read as unmeasured rather than zero.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
