Why NomisLens exists

Some software doesn't zoom.
NomisLens does.

Many critical applications — medical software, clinic tools, legacy systems — don't respond to standard OS zoom. For people with low vision conditions like Stargardt's disease, that's not a minor inconvenience. It's a barrier to doing their job.

NomisLens works at the pixel level, capturing what's actually on your screen and magnifying it inside a floating bubble. It doesn't care what app is underneath. It just works.

What it does

Built for real use. In real workplaces.

🔬

01

Pixel-Level Magnification

Captures actual screen pixels beneath the bubble using fast Windows screen capture. Works on any app — no exceptions.

The magnified area passes all touches and clicks straight through to the app underneath. NomisLens never gets in your way.

Global Hotkey

Ctrl+Alt+Z toggles the bubble on and off from anywhere — even when another app has focus. Always one shortcut away.

🔆

Macular Degeneration

Any condition affecting the macula benefits from targeted, draggable magnification exactly where you need it.

💼

Workplace Accessibility

Legacy software, clinic systems, and enterprise tools that ignore OS zoom settings — NomisLens works on all of them.

Low Vision, Any Cause

Amblyopia, diabetic retinopathy, cataracts — if your screen is hard to read, this tool is for you.

Our story

"My daughter Nomi has Stargardt's disease. She works at a vet clinic and loves her job. The software they use doesn't zoom. So I built something that does."

— Nomi's dad

NomisLens started as a solution for one person. Nomi needed to read patient records, dosage information, and treatment notes in Idexx Cornerstone — software that doesn't respond to standard Windows magnification. Rather than accept that barrier, we built a tool that works at the screen level, below the application, capturing and magnifying whatever is there.

We're publishing it free and open source because nobody should have to fight their tools to do their job.
