Here are settings to enable for Windows 10 to help make the device easier to use for people with low vision. Most of these can be found in the Ease of Access Center in Control Panel.
Make the Computer Easier to See:
High contrast theme– While I don’t use it very often, the option exists to have the computer have a high contrast theme on the desktop and toolbar. The user can choose the contrast theme by clicking “choose a high contrast theme”
Make things on the screen larger/ Change the size of text and icons– I scale mine to 125%
Advanced display settings/advanced sizing of text– I have all font options at size 24 with bold text.
Make things on the screen easier to see– I made the focus rectangle thicker and set the thickness of the blinking cursor to 8. I also turn off all unnecessary animations.
Windows Settings/ Ease of Access/Mouse– My pointer size is the largest one.
Other option– For touch feedback, I use darker, larger visual feedback
