## Description

Theme Inverter is a Chrome extension designed to enhance the readability of web content by inverting the colours of web pages.

You are also able to adjust the percentage of inversion by using a range slider to get just the right level of comfort for your eyes.

This extension allows users to toggle between light and dark themes, making it easier to read text and view content in various lighting conditions, whilst also allowing you to enable/disable the functionality entirely at the press of a switch.

Settings are saved per website (by subdomain), applying the theme on page load. Settings are not globally shared between all websites, as all websites look different.

This extension is perfect for people with astigmatisms, like me. I created it for me, but wanted to share it with you.
