This tool allows users to easily switch between light and dark modes, catering to different lighting environments and personal preferences. It is particularly beneficial for individuals with visual impairments, providing options such as a black background with white text or vice versa. Additionally, the plugin includes eye protection features for prolonged computer use, as well as optimizations for low-contrast web pages to improve readability.
