01 / RESEARCH

A deeper understanding
of vision.

From light entering the eye to the signals that shape perception. Explore the mechanisms of sight in a computational visual laboratory.

Optical systems

Explore three-dimensional eye anatomy and ray tracing, from the cornea and crystalline lens to the retina. See how refractive parameters shape the path of light.

EYE MODELS / RAY TRACING / FOCUS

Image quality

Study aberrations and retinal image quality through wavefront analysis, Zernike decomposition, the point-spread function (PSF) and modulation transfer function (MTF).

WAVEFRONT / PSF / MTF

Neural vision

Explore cone spectral absorption, photoreceptor responses and downstream neural models to understand how light becomes a visual signal.

CONE MOSAICS / PHOTORESPONSE / NEURAL MODELS

Scientific models support research and learning. Simulations are not personal measurements or evidence of clinical validation. Illustrations are conceptual.

02 / THE APP

A visual laboratory.
Now in your hands.

The first iPhone-only
full refraction experience.

Myopia, astigmatism and optional presbyopia checks on a compatible iPhone. No external refraction hardware. Bring visual science and guided checks into one place.

  1. 01

    Confirm your invitation and prepare

    Enter your merchant’s invitation code and confirm the receiving merchant, then check participant information, distance, lighting and device readiness.

  2. 02

    Follow guided visual checks

    Pupillary distance, contrast sensitivity, refraction and astigmatism, with an optional presbyopia check when eligible.

  3. 03

    Keep your records on device

    The laboratory, refraction checks and your records in one app. Keep local records and send new test results to the inviting merchant with your consent.

“First” refers to the combined myopia, astigmatism and presbyopia workflow using only an iPhone, without external refraction equipment.

Results help you understand your refractive status. They do not replace a professional examination or a confirmed prescription. Follow the app’s eligibility guidance.

Curiosity starts
with a closer look.
