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.
為什麼這很重要
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.
- · 專為 Software engineers and knowledge workers over 40 experiencing presbyopia or astigmatism. 打造。
- · 最可能的變現方式：Freemium / SaaS subscription。

差異化
為什麼這件事可能失敗
自我反駁——最重要的信任度信號
- 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.

Numerous professionals shared detailed accounts of how aging and eye conditions made screen reading painful.
