Best Web Accessibility Extension for Vision Impaired

Users with severe vision impairment heavily rely on screen magnifiers (like making text 400% larger). At that zoom level, a single notch of a standard scroll wheel skips entire paragraphs. The best web accessibility extension for the vision impaired is Smooth Scrolling. By scaling the "Step Size" down to a microscopic level and turning up the "Animation Time," visually impaired users gain the required micro-control to smoothly pan highly magnified text precisely where they need it.
