Blind programmers

Have you ever wondered if visually impaired or blind people can code? They can! In fact, there are more blind programmers than you might think. Statistics show that every 200th programmer is blind! But how do they do their job without sight? That’s a valid question. Let us explain.

Visually impaired individuals can use computers almost the same way as everyone else, albeit with some differences. They rely on ears and/or fingers instead of eyes. This is where screen readers come in as essential tools. As the name suggests, a screen reader reads textual content on the screen. Popular ones include VoiceOver for macOS and NVDA or JAWS for Windows. When comparing them, Windows-based screen readers are generally easier to use, while macOS, being more mouse-oriented, can pose challenges for blind users. Users can customize how text or code is read, adapting settings to their preferences. For instance, many prefer minimal punctuation when listening to text, but punctuation is crucial when reading code. Some blind users find it easier to follow code’s punctuation and flow using a Braille display. Braille allows blind individuals to read line by line using their fingertips and tactile sensation, enhancing focus on content. Additionally, Braille users can navigate code faster with greater attention to detail, which is particularly useful during debugging. Assistive technologies also enable users to adjust font size, color, and other features to enhance readability.

However, programmers with visual disabilities face daily challenges, especially with graphical tools that are difficult to adapt for screen readers. Overcoming these challenges often requires time and innovative workarounds. Another issue is that reported accessibility problems are sometimes not taken seriously by companies and tend to be ignored. Furthermore, complex commands requiring extensive typing can make work even more challenging for blind programmers. Screen reader users must also remember a considerable amount of information. Lastly, many coding courses are inaccessible to screen readers, although improvements are being made in this area.

Overall, while challenges persist, advancements in assistive technology and increased awareness are making coding more accessible to visually impaired individuals.
