See the web the way your eyes were meant to
Glasses correct your vision. Websites don't know that. 4Eyes is a Chrome extension that adapts every website to your eye prescription in real time. Enter your SPH, CYL, Axis, and ADD values and it automatically adjusts brightness, contrast, letter spacing, line height, and font weight across every site you visit. It also recommends the best fonts for your prescription — Atkinson Hyperlegible, Lexend, Nunito, or Source Serif 4. Free. Works everywhere.

I don't have a prescription. But I saw a problem worth solving.
People with myopia, astigmatism, and hyperopia correct their vision with glasses or contacts — but screens still cause strain because no website is designed around your specific eyes.
So I built 4Eyes.
It's a Chrome extension that takes your eye prescription and automatically adapts every website you visit — adjusting brightness, contrast, letter spacing, line height, font weight and recommending the best fonts for your vision condition.
Built with FastAPI, Supabase, and Chrome Manifest V3. Launched on the Chrome Web Store.
Sometimes the best products are built by people who observe a problem rather than experience it.
