Astigmatism-Optimized Web Readability Extension
A browser extension that instantly converts forced dark-mode websites into eye-friendly, low-contrast "soft light" themes. It specifically increases font weights and reduces background contrast to eliminate the glowing text effect (halation) that causes headaches for users with astigmatism.
Pourquoi c'est important
You sit down at your desk ready to work, but the modern developer tools you rely on force a trendy, high-contrast dark theme. Because of your astigmatism, the bright white text bleeds into the deep black background, creating a glowing halo effect that makes the words fuzzy. After an hour, you have a headache and your eyes feel exhausted. You try to find a light mode setting, but the developers didn't bother to build a good one. Existing accessibility tools only filter blue light or force dark mode, leaving you with no way to make your daily digital environment physically comfortable to look at.
- · Conçu pour Software engineers and knowledge workers over 40 experiencing presbyopia or astigmatism..
- · Monétisation la plus probable : Freemium / SaaS subscription.

Différenciation
Pourquoi cela pourrait échouer
Auto-contre-argument — le signal de confiance le plus important
- 1The sheer complexity of modern web frameworks (like React/Shadow DOM) might make global CSS overrides too buggy to be reliable.
- 2Users might expect this kind of accessibility feature to be completely free, rejecting the subscription model.
- 3Apple or Google could introduce native OS-level astigmatism contrast filters, destroying the unique value proposition.
