## Description

Opthy is a fast, contactless Pupillary Distance (PD) measurement tool powered by EssilorLuxottica. With a few taps on your iPhone, Opthy turns your device into a 3D body scanner to capture PD and IPD for far vision, helping you choose glasses with a precise, personalized fit.

Designed for adults with single-vision prescriptions between -5D and +5D, Opthy guides you through a quick scan and provides PD results you can use when ordering prescription glasses online. Note: not suitable for bifocals, progressives, or under-18 use.

## Review summary

Many reviews say Opthy often fails to function, repeatedly requiring precise placement of the head in the oval, careful distance, and good lighting. Users report long setup times, repeated attempts, and readings that vary between tries. While a minority praise its ease of use and ability to measure PD when it works, the dominant themes are unreliability, strict positioning, and lighting sensitivity, suggesting the app can be useful only in favorable conditions.

### Pros

- PD measurement capability when the app functions
- User-friendly interface when it works
- Occasional positive feedback praising ease of use (e.g., 'Excelente application', 'user friendly')

### Cons

- Does not work reliably; many users report it failing to measure or giving errors
- Requires strict positioning/holding: head must be placed in the oval, precise distance, and minimal movement
- Readings are inconsistent and can vary between attempts
- Time-consuming and frustrating to use, with repeated prompts and long setup
- Highly sensitive to lighting and illumination conditions
