4Eyes

What it does

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.

4Eyes reads your eye prescription and instantly adapts brightness, contrast, letter spacing, font weight, and more across every website — so every screen feels like it was designed just for you. No configuration required. No eye tests needed. Just your prescription and 4Eyes does the rest. Every feature in 4Eyes is designed around actual vision science, not just aesthetic preference. Blue light blocking, UV, and photochromic lenses all introduce subtle color distortion. 4Eyes detects your coating type and corrects the shift — so your screen looks exactly as it should, even through your lenses. Download 4Eyes for your platform and install the Chrome extension. Setup takes less than 2…from 4eyeslux.io

  Homebrew 6.0.0▲1,481

  Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

  Performative-UI – A react component library of design tropes▲1,181

  Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
