Use the accessibility features of our website
NEI uses a number of features designed to make our website easier for everyone to navigate and read. Learn more about our accessibility features, and share this information with other people who would benefit from using them.
Increase zoom to see larger text
When you increase the text size in your web browser, the site layout will adjust so the text still fits in the width of the page. You won’t have to scroll from side to side in order to read a page.
Use high contrast mode for easier reading
If you are visually impaired or have trouble reading on a screen, try using high contrast mode. This setting lets you view our site with a dark background and light text, which can make it easier to read. You can turn on high contrast mode under the accessibility settings on your computer or mobile device.
Turn on “prefers reduced motion” to limit motion
Our website works with your browser or device’s “prefers reduced motion” setting. If you have vertigo or motion sickness when you see sudden movement (like clicking a link that jumps you down the page suddenly), try using this setting to reduce or stop animations and motions on webpages.
