Some software doesn't zoom.
NomisLens does.

Many critical applications, like medical software, clinic tools, and legacy enterprise 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.

Built for real use. In real workplaces.

If the screen is hard to read,
NomisLens is for you.

Built for Stargardt's disease, but useful for anyone who needs more from their screen.

👁️

Stargardt's Disease

Central vision loss that makes fine detail reading nearly impossible. NomisLens was built specifically for this.

🔆

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.

Meet DisplayScaler.

NomisLens magnifies one spot inside one app. DisplayScaler makes your whole screen bigger in a single click.

Two giant, high contrast buttons step the entire Windows display scale up or down, instantly, and the change sticks across restarts. It drives the same setting that is normally buried deep inside Windows Settings, from a bright widget you can actually see and reach. It works in every app, needs no admin rights, and does one thing well. Some software will not zoom on its own, and that is what NomisLens is for. But some days you just need the whole world bigger. Most low vision users want both. They are sister tools, built for the same eyes.

"Someone I love has a condition that affects her central vision. She works hard at a job she's passionate about, and the software she relies on every single day simply doesn't zoom. So I built something that does."

NomisLens was born out of frustration with a problem that shouldn't exist. Stargardt's disease causes progressive central vision loss, making fine detail, like text, numbers, and patient records, increasingly difficult to read. Standard Windows magnification helps on most apps, but critical workplace software, especially in medical, veterinary, and enterprise environments, often ignores it entirely.

Rather than accept that barrier, we built a tool that operates below the application layer, capturing actual screen pixels and magnifying them inside a floating bubble that works everywhere, on anything, without exception.

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

Two tools.
Both free.

Two .exe files. No install. No account. No cost. Just download and see better.
