Tips for those with visual impairments
You may find that lowering your screen resolution helps you see text and images more easily. As a start, try a resolution of 800 x 600 (in Windows). Learn more about how to change your screen resolution.
While you’re working, you may want to magnify certain areas of the site. Use the zoom-in hotkeys available in most browsers.
Users who need to magnify a page may find that operating system or third-party magnification programs work best. These programs have more options for magnification strength and other display settings, including color and contrast.
Specifying color and contrast settings
Some users need a higher or different color scheme or color contrast to see content on pages. For example, you may find it easier to see light text on a dark background, dark text on a light background, or text in grayscale.
