| Visual disabilities affect how people see, including partial vision in one or both eyes, not seeing at all, or seeing in a range of different ways including colors and brightness. | Collage of 4 people using digital devices in various settings. |
| People who are blind use assistive technology on computers and mobile phones called screen readers. These software tools can read the information on the screen out loud, or they can present it in Braille. | Man with sunglasses uses laptop at desk. |
| Screen readers can process websites and apps with correctly coded headings, lists, links, button, and other structures much better. [Computer voice] Bird migration is the regular seasonal movement, often north and south along a flyway, between breeding and wintering grounds. Many species of bird migrate. Migration carries high costs. A map of the world, showing some example bird migration routes, image. | Website scrolls with text and images defining bird migration terms. The paragraph read by the screen reader is highlighted. |
| Websites and apps also need to work with the keyboard, and have text alternatives for images. | Man continues to use his laptop. |
| However, most people with visual disabilities are not blind but have some form of low vision. This means that people can partially see, just not clearly or within the full range of vision. | Woman on couch uses her mobile phone. She looks frustrated while trying to see something. |
| Some people with low vision use screen magnification software as a digital magnifying glass to enlarge everything on the screen. This includes images, text, and the mouse pointer. With this, people only see small parts of the screen at a time, so they rely on visual cues and consistent design in websites and apps to stay oriented and navigate effectively. | On her phone she activates the zoom feature which enlarges the view of a webpage. The page pans across the screen to take in all the content. |
| Others with low vision might not use the same assistive technology. They might adjust properties in the web browser or operating system, such as increasing the default text size, to better see the text. Websites and apps that are programmed and designed to adapt to the properties set by users, such as different text sizes, font type, and line spacing, allow people to use the content without the text overlapping, getting cropped, or requiring them to scroll both vertically and horizontally. | Man uses laptop but struggles to see the current webpage. He presses Control+ to increase the text size, but the words on the page start to overlap and become unreadable. |
| People who cannot distinguish certain colors are often called “color blind”. Websites and apps that avoid text with low contrast are easier to use. | Woman uses tablet while sitting on couch. |
| It’s also important that websites and apps don’t use only color to communicate information, but do use text and symbols in addition to color, such as an asterisk to indicate required input fields. | A web form for shopping checkout shows required fields both with red text labels and an asterisk. Instructions explain “Required fields are marked in red with an *”. |
| Some people are sensitive to bright light, so it’s important that websites and apps can adapt to the color schemes that people might set in their browsers and operating systems. | A search results webpage shown with white background and black text is changed to a black background with white text by selecting a browser setting to “Dark Theme”. |
| You can help make technology accessible to me. Accessibility: It’s about people. | Woman speaks the phrase, “You can help make technology accessible to me,” then pans to a collage of 12 people with different colored backgrounds. |
