Oh Geez.
It's just eyes, you know?
Who needs to know all this stuff?

Ten-minute walk-through. Inputs: your current numbers, a few questions about how you use your eyes. Outputs: a working theory of why the numbers drifted and a concrete first move. Closest thing this lab does to a free first consult — start here if you don't have a measurement to log yet.

Outputs: pupillary distance, in millimeters. Inputs: any rectangle of plastic, held to your forehead. Built because the local optometrist won't write it down for you. Functions in 1.0 ± 0.2 mm.

Demonstrates the brief sharpening reflex that the establishment forgot to mention exists. Subject participation required. Yes, that means you. Most subjects fail to notice the effect on the first three attempts. This is by design.

Operate →

Live readout, eye-to-screen, in cm. Bands the data into healthy / strain / clamping. Subjects who insist they sit far enough are encouraged to check. Most are off by 15 – 20 cm. Telemetry persists across sessions.

Operate →

Vertex-distance compensation between the corneal plane and the spectacle plane. Inputs: any diopter you have, or a blur-edge distance you measure with the camera. Outputs: the matching number on the opposite plane, rounded to 0.25 D, plus the full conversion chart from −1.00 to −12.00 and +1.00 to +8.00.

Operate →

Daily log of subject blur edge, in cm. Charts the migration over a 14-day field study, projects a 12-month population trajectory under three engagement modes. Everyone gets the same logging tool, plain.

Operate →

Outputs: cylinder, axis, and sphere per eye. Inputs: six striped patterns the lab rotates for you, three captures per orientation, the usual wallet card. The cm method, extended to direction — meridian by meridian, fit to Sturm's conoid. Irregular patterns get flagged for a clinician; the autorefractor was not invited.

Operate →

Outputs: myopia diopter per eye. Inputs: the camera, any wallet-size card, and your willingness to move the phone slowly. Same cm method the centimeter ledger uses, just measured by the camera. Approximate, not clinical — but the same approximation the optometrist starts from.

Operate →

A chat advisor trained only on EndMyopia material. Ask it your diopter and habit questions and get a focused read instead of generic AI word-salad. Not medical advice, not a stand-in for the forum.

Operate →

Inputs: the 20/xx line you were read off the wall chart, or the minus number on your glasses paperwork. Outputs: what that figure means in rooms, road signs, and faces; where it sits on the mild-to-high scale; and whether “legally blind” actually applies to you (almost certainly not — the definition is misquoted constantly). No camera, no calibration. Sixty seconds.

Operate →

Inputs: the numbers the optician printed and did not explain — OD, OS, SPH, CYL, AXIS, ADD, and the PD they left off. Outputs: each line in plain words, where the number sits on the standard scale, what the bare eye actually resolves, and the lens index the shop will try to upsell. Reads the paper the way the person who wrote it assumed you never would.

Operate →

Inputs: the same numbers off the same paper, plus three taps — what the glasses are mostly for, how big the frame is, which side of 40 you are on. Outputs: the index band, the material and its Abbe cost, and the lens type, with the two-pair option the counter does not offer laid out beside the bifocal and the progressive it does.

Operate →

Inputs: a bank card held to the glass, a distance you step back to or let the camera read, and five Sloan letters at a time. Outputs: the 20/xx line each eye reaches, the band it sits in, and the two lines the screen refused to draw because the pixel grid, not the eye, would have been the thing under test.
