EyeCBest is a browser extension, which increases the visual ability for the visually challenged reader of a webpage. This extension enables the user to change the font, size and boldness of website text with one click. The user can choose from a range of font types and increase text size up to 400%. All text on the webpage and those visited afterwards will be displayed in the same manner until EyeCBest is deactivated. It thus provides a simple solution for those struggling with contrast sensitivity, macular degeneration and other eye issues.
