Vision screening, from your phone

See how your eyes are really doing, before it's an emergency.

Ten clinical-style vision tests, from an AI cataract check to a full eye chart, for yourself or a clinic's patients.

Launching on iOS & Android soon See the ten tests ↓

Ten tests, the kind an eye clinic actually runs

Each one is modelled on a real clinical screening tool, adapted for a phone screen and, where it matters, for a voice.

01

AI Cataract Screening

Photograph each eye; an on-device + cloud model flags early signs of cataract.

02

Visual Acuity (Snellen)

The standard letter chart, read aloud and scored across eight lines down to 20/20.

03

Color Vision

Ishihara-style number plates that surface red-green color deficiency.

04

Contrast Sensitivity

How faint a shape you can still make out, often the first thing to fade.

05

Visual Field

Checks your peripheral vision for blind spots a straight-ahead test would miss.

06

Amsler Grid

A grid of straight lines used to catch early distortion from macular changes.

07

Duochrome

A red/green split screen used to fine-tune which side your prescription favors.

08

Astigmatism

A radial line fan that reveals an uneven corneal curve.

09

Tumbling E

A single E pointing four ways, for anyone who can't read letters yet.

10

Landolt C

A broken ring, the international standard for directional acuity testing.

Acuity reference

What a line on the chart actually means

Each row is a smaller letter than the last. The bottom row, 20/20, is the line a person with normal vision can read clearly from 20 feet away.

CataPred is a screening tool for awareness, not a medical diagnosis. A result outside the typical range is a reason to see a qualified eye doctor. It isn't one on its own.
