Setup: live camera needs HTTPS or localhost (host the folder, e.g. Netlify Drop, and open in Chrome/Safari). No HTTPS? Use 📷 Camera app on the capture screen — it works everywhere, including this file opened directly.

Colour swatches show approximate activated appearance for visual demonstration. Brand and product names are trademarks of their respective owners; consult current manufacturer catalogues for available colours and lens technology.

Visual demonstration only. Actual lens response varies by lens technology, UV exposure, temperature and environment. This does not measure UV.
Visual preview only \u2014 for showing customers how frame/lens shapes look. This does not change measurement or boxing.
Estimated from lens power and diameter. Actual thickness depends on base curve and surfacing \u2014 confirm with the lab.
Validation traffic-lights use half the tolerance as the green band. Fixation default applies to new measurements; it can still be changed per capture on the calibration step.

Validated against ISO 8624 (boxing system) and ANSI Z80.1 (ophthalmic tolerances). Measurements outside tolerance are rejected for lab order.

BVD, pantoscopic tilt and face-form wrap need a profile (side) capture or depth sensor for automatic measurement — planned for v2. Enter measured values from your dispensing tools; defaults shown are population-typical.
Choose a colour on the right. The overlay uses each iris centre and diameter measured from the customer face.
Visualisation only. Actual contact-lens appearance varies by natural iris colour, lighting and lens brand. Confirm with a physical trial pair before dispensing.
Simulation only — actual lens colour, darkness and activation speed vary with product, prescription, temperature and UV conditions.

Point the camera at a window or step toward the door \u2014 the lens darkens as real-world brightness rises, and clears in shade, just like a photochromic lens. Visual demonstration only; actual activation depends on UV, temperature and the specific lens.
