Three steps to
a sharper screen

No hardware changes. Just install, enter your glasses prescription, and your screen adjusts to suit you.

01
📋

Enter Your Prescription

Type in the numbers from your glasses prescription — the same ones your optician gave you. DOA works with SPH, CYL, AXIS, and ADD values.

02

DOA Adjusts Your Screen

Think of it like noise-cancelling headphones, but for your screen. DOA works out how your display needs to look so that when you see it without glasses, it still looks sharp to you.

03
👓

Remove Your Glasses & Look

Take your glasses off and look at your screen. Read, browse, work, and watch — then toggle DOA off to compare. The difference is clearest when you go back and forth.

A few things worth
knowing first

DOA works differently from most apps. Understanding how it behaves will save you from thinking it's broken when it's actually working exactly as it should.

👓

Take your glasses off first

This sounds obvious but it's the most common mistake. DOA is designed to be used without glasses. If you're wearing them while testing it, the screen will look over-sharpened or distorted. Take them off, then look.

🎚️

The effect is subtle by design

DOA makes fine adjustments that your eye processes unconsciously. Toggle it off and on while looking at small text and the difference becomes obvious in comparison.

📏

Distance matters

When calibrated for 50cm (for example), 5cm too close or far will make the adjustment not be as precise. Sit at your set screen distance.

🔢

Prescription Strength

Stronger prescriptions (−3.00+) see immediate results. Mild ones see a more subtle change since their eyes already adapt fairly well to close up content

🖥️

Your screen matters too

Display resolution plays a key role in correction quality. Lower PPI/DPI screens may limit effectiveness. Check your monitor's specs when setting up your prescription card.

🌡️

Hyperopia

Far-sighted users often see the clearest improvement with close-up screen tasks.

Built for every eye,
every screen

One tool. Works with your glasses prescription. Runs at 60fps across every app on your screen.

🎯

Works With Your Prescription

Enter the SPH, CYL, AXIS, and ADD values from your glasses and DOA adjusts your screen display to match. Works with most common prescriptions.

60fps, Near-Zero Lag

Runs entirely on your GPU. There's a 30–50ms overlay delay — imperceptible during reading, typing, and browsing. Ideal for everyday use.

Color Filters

Color adjustment modes for Protanopia, Deuteranopia, and Tritanopia — for people who have difficulty distinguishing certain colors. Works on its own, no prescription needed.

🖥️

Multi-Monitor Support

Apply different display settings per monitor — useful when screens are at different viewing distances. Premium feature.

🔒

Privacy-First Design

DOA never captures Windows system UI, Start menu, login screens, or UAC prompts. Your sensitive information stays protected by design — not just by policy. Everything is processed locally on your device and never transmitted.

🛡️

What DOA never sees

Some Windows elements are protected by the OS and will not appear in DOA's display layer — keeping your data private.

Works for
how you see

DOA works with the most common glasses prescriptions — here's what each one means in plain English.

🔭

Near-sighted

Things far away look blurry. DOA adjusts your screen so text and images look sharp even without your glasses on.

🔬

Far-sighted

Things close up are harder to read. DOA makes small text and fine detail on your screen easier to see up close.

💫

Astigmatism

Everything looks a bit stretched or smeared in one direction. DOA adjusts for that based on your CYL and AXIS values.

📖

Reading glasses

If you use reading glasses for screens and books, DOA can adjust your display so reading is more comfortable up close.

👀

Binocular imbalance

When both eyes don't naturally align on the same point, screens can cause double vision or persistent strain. DOA's prism correction adjusts for this offset so both eyes land comfortably on the same image.

More than just
prescription support

Color adjustment modes run as a single display pass — no setup, no calibration, and fully compatible with any active prescription profile.

Protanopia

For people who have difficulty seeing red. DOA shifts and amplifies red-spectrum colors so they stand out more clearly on screen.

Deuteranopia

The most common type — trouble telling red and green apart. DOA adjusts the color balance so those tones are easier to distinguish.

Tritanopia

For people who have difficulty seeing blue and yellow. DOA remaps those colors on screen so they become visually distinct.

Common questions,
straight answers

DOA works with most standard glasses prescriptions including near-sightedness, far-sightedness, astigmatism, and reading glasses. Very strong prescriptions may see less improvement depending on your screen's resolution and size. The free tier lets you try it with no commitment.
No — DOA adjusts your screen display, not your eyesight. It's designed for screen use only. You'd still need glasses for everything else — driving, reading printed text, and anything away from your screen.
No. DOA is a display accessibility tool — it adjusts how your screen looks. It is not a medical device, is not regulated as one, and does not treat, diagnose, or replace any professional eye care. If you have concerns about your eyesight, please see a qualified eye care professional.
Currently Windows 10 and 11 only. macOS and Linux support are planned for the future.
No. DOA only adjusts your screen — it has no effect on your actual eyesight. It's a tool for making your screen easier to use when you don't have your glasses on. It cannot improve, treat, or change your vision in any way.
