Three movements. One outcome. A vision test from a smartphone, standardized lenses from a single supplier, and delivery through networks that already reach every street.
A simple, self-guided refraction test administered through a smartphone. Clinically validated to ISO 10342 and ANSI Z80.1 prescription tolerances. No technician required.
Three standardized frame widths. One lens specification. Bulk orders direct from manufacturers. We absorb scale — the customer absorbs savings.
Third-party logistics networks — the same fleets delivering food, parcels, and ride-share — drop eyewear at the customer's door. No storefront. No warehouse.
Two interfaces from the same screening: a consumer radar for self-awareness, and a clinical prescription an optician will accept.
At Jinshan Elementary School in northern Taiwan, we tested 52 students using our phone-based refraction system against subjective refraction — the clinical gold standard. Every metric that matters for a safe prescription came in at or below international thresholds.
The system passed on accuracy, systematic bias, agreement range, and repeatability. These are not marketing numbers. They are the four diagnostic floors set by the International Organization for Standardization and the American National Standards Institute for clinical acceptability.
| Metric | Our Threshold | Clinical Context | Proof Point | Standard |
|---|---|---|---|---|
| MAE vs subjective Rx | ≤ 0.40 D | Inter-examiner MAE ~0.25–0.35 D | Accuracy within clinical norm | ISO 10342 |
| Mean bias (absolute) | ≤ 0.25 D | No systematic over/under-estimation | No directional drift | ISO 10342 |
| Limits of agreement (98%) | ± 1.00 D | Rx tolerance ±0.25 D; ±1.00 D clinical ceiling | Agreement range clinically safe | ANSI Z80.1 |
| Repeatability SD | ≤ 0.20 D | Autorefractor SD typically ≤ 0.20 D | Consistent repeated readings | ISO 10342 |
Custom lens grinding is the single largest cost center in conventional eyewear manufacturing. It is also, for the vast majority of users, unnecessary. By offering three frame widths — small, medium, large — with a shared lens specification, we compress an entire supply chain into a single SKU pipeline.
The frames accommodate nearly every adult face. The lens stays identical. The supplier runs one production line instead of thousands. The savings flow directly to the person who needed glasses in the first place.
Identical specification across every frame width.
The rider on the motorcycle is already there. The parcel-delivery network is already routed. The ride-share app is already installed on the customer's phone. We do not need to build infrastructure — we need to borrow it.
By riding on existing third-party logistics (3PL) networks, we skip the most capital-intensive part of traditional optical retail: warehousing, storefronts, and a delivery fleet. Our product moves through the same veins that already carry food, parcels, and people.
