FL3R Accessibility Suite adds an accessibility control panel for visitors to your WordPress site. It was specifically designed for users with visual impairments.
Allows the visitor to: 
* Change the text size of the website 
* Choose from five pleasant and high-contrast themes 
* Show, hide or display grayscale images 
* Use text-to-speech on your device to hear the settings available in the control panel 
* Choose between the highly readable Arial or OpenDyslexic font, developed for dyslexic people 
* Show or hide content from third party sites
All themes have been tested with the <a href="https://webaim.org/resources/contrastchecker/" rel="nofollow ugc">WebAIM Contrast Checker</a> tool.
You can add the icon to access to accessibility control panel via shortcode, php or widget.
