Amblyo: Lazy Eye Training
Amblyopia Eye Exercises Daily
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
32 exercises for lazy eye, including two-eye games that need red-cyan glasses. Progress tracking that says "no clear change" when that is the truth.
Amblyo is a daily eye-training app for amblyopia — the condition usually called
lazy eye, where one eye's vision stays blurred because the brain has learned to
lean on the other one.
It is an exercise app, not a replacement for eye care. It doesn't replace an eye
examination, glasses, patching, or anything an optometrist or ophthalmologist
recommends.
WHAT'S IN IT
32 exercises across three groups:
• 14 single-eye exercises that need nothing but your screen — spotting faint
patterns, reading tiny gaps in rings, judging which line is offset, following
a moving dot, reading progressively smaller print.
• 10 two-eye exercises that need a cheap pair of red-cyan glasses. These are the
ones that can't be done with one eye at all: a shape hidden in speckle that
only appears when both eyes fuse, a game where one eye sees the ball and the
other sees the paddle, a search where each eye carries half the clue.
• 8 games built on the same mechanics, for children who won't sit through the
plain versions.
DIFFICULTY THAT FOLLOWS YOU
Every exercise runs a staircase: three right answers make it harder, one wrong
answer steps back. Within a couple of minutes it settles where you're right
about four times in five — uncomfortable, and the level where the visual system
actually adapts.
MEASURED IN REAL SIZES
The app asks you to measure your screen once and set your viewing distance. Every
stimulus is then specified as an angle rather than a number of pixels, so a
difficulty level means the same thing on a phone and on an iPad. A few exercises
can't show their hardest levels on a small screen, and the app says so rather
than pretending.
PROGRESS YOU CAN TRUST
The Progress screen won't draw a line until there's enough data to support one.
It needs at least eight practice days of an exercise before claiming a direction,
and it says "no clear change yet" when the numbers don't separate from noise.
That's less encouraging than a rising graph, and it's the only version worth
having.
If two four-week blocks pass with no measurable change, the app says so and
suggests seeing an eye care professional — even though that's against its own
retention interest.
SAFETY
• Sessions are capped, and shorter for younger age groups.
• Breaks are offered part-way through; "my eyes feel tired" ends a session
immediately without losing progress.
• Nothing flickers faster than 3 Hz and no exercise inverts the whole screen's
brightness, for anyone photosensitive.
PRIVACY
Everything stays on your device. There is no account, no server, and nothing is
uploaded. Delete All Data in Profile removes every profile, session and
measurement, and there is no cloud copy to restore from.
WHAT IT DOESN'T CLAIM
No exercise in this app has been shown to restore normal vision, and no app can
promise that. Getting better at a trained task is a real result, and it is not
the same as no longer having amblyopia. The evidence badge on every exercise
says how well supported that specific exercise is, including the ones where the
honest answer is "limited".
