It’s easy for a non-disabled person to access things online; more often than not, software is designed and built for them. People with no barriers can easily use their mouse to point, click and navigate. Content is easily read (or skimmed) and useful context can be gained from colourful images and graphics.
But what if you are older or have a visual impairment and can’t see the words on the page? What if you are blind or have a motor control disability that prevents you from using a standard mouse?
22% of Canadians have at least one disability.
Navigating the web isn’t a straightforward experience if you are part of the 6.2 million Canadians living with a disability. How can they hope to navigate the online world successfully when it isn’t built for them?
It’s clear that digital products designed for disabled users have a variety of benefits for your organization, and the world. With that in mind, this article will focus on visual impairment – a disability that over one million Canadians struggle with – so you can begin to understand what their interactive experience is like, and how to make it as accessible as possible.
There are over 1.5 million Canadians with visual impairments, ranging from partial sight to uncorrectable blindness. Living with “low vision” can include having impairments such as blurred vision, field of vision loss and colour blindness and these struggles are often overlooked when software is designed and built.
The following scenarios can help us to better understand issues visually impaired users have when interacting with software.
Carol is 66 years old and was recently diagnosed with glaucoma, which causes her vision to be blurred and her peripheral eyesight to be blocked. Her glasses prescription and medication help to ease some of the symptoms, but navigating the web is a continued challenge for her. Her field of view is limited and often times content is blurry or completely illegible to her.

Like much of the older population, Carol doesn’t consider herself disabled, so she has never thought about getting any assistive technology such as a screen reader. This often results in her manually enlarging text through her browser, but this frequently causes the text to reflow poorly, continuing to make reading a challenge.
How can we remove barriers in our software for Carol?
Raymond has red and green colour blindness, a visual disability that affects 1 in 12 men. When red and green are presented or used in combination, Raymond can’t distinguish between the two, since they both look yellowy-brown to him. This often presents barriers online when colour alone is used to indicate meaning.

Raymond is an avid online shopper, but has difficulty making choices if colours aren’t labelled and this has many times resulted in him purchasing the product elsewhere. Success and error messages also cause frequent frustration for him, especially when red and green are the only things used to let him know if an action was completed.

Lin has been legally blind since she was 14 years old. Like many other blind users, Lin does not read Braille. She uses a screen reader to access content online, which reads the hierarchy on the page out loud to her, allowing her to navigate and find information effectively.
Often times websites and web apps are poorly coded, jumbling the content hierarchy and resulting in non-navigable content; this forces her to either listen to the content on the page in the wrong order, or abandon the page altogether. Lin also misses important context present in images, graphics or icons if they aren’t accompanied with text alternatives.

Accessibility can be achieved without damaging your product’s aesthetics, brand, or design, and it’s in the best interest of all users. After all, if you’re operating at a large scale, a smaller percentage of users can actually translate to hundreds, thousands, or even millions of customers. You don’t want to miss out on those users, do you?
Take the next step and ensure your products are accessible. If you have an existing product, run an accessibility test using a tool like Wave (it’s free!) If you are in the process of building a new piece of software, talk with your design and development team and ensure you have an accessibility plan in place.
Accessible Canada Act – Federal accessibility legislation passed in June 2019 whose purpose is to achieve a barrier free Canada by 2040.
World Wide Web Consortium (W3C) – Develops and provides international standards for the Web.
Wave – A free web accessibility evaluation tool that can be run on any website or web app.
Material Design Accessibility Guidelines – Google’s guidelines for implementing accessible design.
WebAIM Contrast Checker – Use this tool to check if colours are meeting contrast standards.
NoCoffee Extension – An extension that can be added to your browser to simulate what people with visual impairments experience.
