Visor

Visor (https://bit.ly/3KVq0b7) is a Google Chrome extension that is a screen dimmer and reading aid. Visor may also help with fluency, eye-strain, concentration and comprehension whilst reading.

 
Visor offers overlays and point of focus features that may assist users with visual perceptual difficulties such as Dyslexia, Scotopic Sensitivity Syndrome and Visual Stress. 

Visor also uses a point of focus feature, designed to help further reduce visual confusions and the tendency to skip lines. Visors horizontal focal point tracks your mouse, giving you full focus to the content being read, while reducing the visual noise of the surrounding page.
