Approximately 2% of the global population has visual impairments. But the bigger question is, is it their fault to have disabilities, or don't they deserve to be treated equally? The answer is straight “No”! Disabilities highlight the importance of creating a society that recognizes and respects the wide range of needs, obstacles, and lived experiences of individuals from all backgrounds. Everyone deserves equal access to essential quality-of-life resources, regardless of physical or sensory limitations. Supporting people with complex disabilities such as deafblindness requires implementing accessible website features that cater to both visual and hearing impairments, ensuring a more inclusive digital experience for all users.
Creating website accessibility for visually impaired users involves integrating various digital solutions, accessibility practices, and content enhancements to offer an inclusive browsing experience. Building an accessible website with assistive technologies requires multiple strategies and techniques, including keyboard-friendly navigation, descriptive alt text, captions, screen reader compatibility, and clear, easy-to-understand language.
Various Levels of Deafness & Hearing Impairment
According to the National Association of the Deaf (NAD), people with hearing impairments experience and engage with communication in different ways depending on the level and nature of their hearing loss.
Hard of Hearing (HoH): Individuals in this group may experience partial hearing loss or varying degrees of hearing difficulty, but they are not completely deaf.
deaf (lowercase “d”): This term often refers to individuals who have hearing loss but may not identify with the broader Deaf culture or community. In many cases, their hearing impairment developed later in life.
Deaf (capital “D”): People who identify as Deaf with an uppercase “D” are typically part of the Deaf community and primarily communicate through sign language. Many are born with profound hearing loss and have embraced Deaf culture throughout their lives.
Various Levels of Blindness & Vision Impairment
The classification of vision impairment is determined by several factors, including the availability of treatment, the potential to prevent or manage eye conditions, and the effectiveness of rehabilitation through assistive devices. Considerations such as mobility, navigation in inaccessible environments, use of public transportation, and the ability to process visual information also play an important role.
According to the World Health Organization, the majority of people living with vision impairment or blindness are aged 50 and older. The most common causes include uncorrected refractive errors and cataracts. Globally, at least 2.2 billion people experience either near or distance vision impairment, with nearly half of these cases considered preventable. Different categories of visual impairment and blindness are typically defined based on the severity of near and distance vision loss.
Distance Vision Impairment Levels
People with distance vision impairment may experience mild, moderate, or severe vision loss, as well as complete blindness. These categories are determined through clinical assessments of visual ability, with specific numerical criteria outlined by the WHO.
Near Vision Impairment Levels
Near vision impairment is generally identified when a person’s visual acuity is worse than N6 or M.08 at a viewing distance of 40 centimeters.
Common Barriers of Inaccessible Website
Although accessibility standards and technologies have improved, many websites continue to create challenges for blind and low-vision users, limiting their ability to navigate and interact effectively online:
- Missing Alternative Text: More than half of website images remain inaccessible to users with visual impairments. Without meaningful alt text, screen reader users are unable to understand the purpose or context of images.
- Improper Content Structure: Inaccurate or absent headings, lists, and page landmarks can disrupt screen reader functionality, making navigation confusing and inefficient.
- Limited Keyboard Accessibility: Individuals who rely on keyboard-only navigation face difficulties when websites lack a logical tab sequence or trap keyboard focus within certain elements.
- Insufficient Contrast and Readability: Low color contrast, tiny fonts, and non-adjustable text sizes can make content difficult for users with low vision to read comfortably.
- Inaccessible Multimedia Content: Audio and video materials without captions, transcripts, or other accessible alternatives may prevent users with hearing or visual impairments from accessing important information.
Deaf Accessibility & Vision Impairment Inclusion Online
Because people primarily absorb and interpret information through sight and hearing, individuals with deafness, blindness, or combined deafblindness often encounter significant barriers when interacting with digital platforms and communication technologies. These challenges become even more complex when both hearing and vision impairments occur together.
Web accessibility for people with deafblindness requires websites and digital platforms to ensure that visual and audio content is logically organized and supported by alternative interaction methods. By combining accessible design practices with assistive technologies, organizations can create a more inclusive and barrier-free online experience.
Assistive Technologies
Depending on the type and severity of a person’s condition, assistive technologies help users rely on their strongest remaining sense to interact with websites, apps, and digital content. Individuals with profound deafblindness may also depend on tactile or haptic technologies for communication and navigation.
Some common assistive tools include:
- Screen Readers: Convert on-screen content into voice audio for users with visual impairments.
- Voice Recognition and Dictation Tools: Enable users to navigate websites and complete actions using verbal commands.
- Refreshable Braille Displays: Translate digital text into tactile Braille output that can be read in real time.
Website Accessibility for Visually Impaired Users
To ensure assistive technologies function effectively, websites should follow established accessibility standards such as the World Wide Web Consortium (W3C) Web Content Accessibility Guidelines (WCAG). Adhering to these standards helps developers create websites and applications that are compatible with screen readers, Braille devices, keyboard navigation, and other accessibility tools.
Below are several important accessibility practices that support users with varying degrees of deafblindness:
- Keyboard Accessibility
Users with visual impairments may not be able to operate a mouse or track a cursor visually. Websites should therefore support complete keyboard navigation, allowing users to move through interactive elements using keys such as “Tab” and activate functions using “Enter.” Logical keyboard navigation is essential for an inclusive browsing experience.
- Clear and Logical Website Structure
Simple, intuitive, and predictable website layouts improve usability for all visitors, especially those who rely on assistive technologies. Proper heading structures, organized menus, and semantic page layouts make navigation easier for users employing screen readers or Braille devices.
- Descriptive Alt Text for Images
Images containing meaningful information should include descriptive alternative text (alt text). This hidden text enables screen readers and Braille displays to communicate the image’s purpose or content to users who cannot see it. Effective alt text should be concise, accurate, and easy to understand.
- Captions, Transcripts, Sign Language, and Clear Audio
Videos and multimedia content should provide accurate closed captions and written transcripts so that users with hearing impairments can access the information. Some organizations also include sign language interpretation. Clear audio quality and reduced background noise further improve the accuracy of captions and transcripts for users with combined hearing and vision disabilities.
- Multiple Communication Options
Accessible communication should extend beyond phone support. Websites should provide alternative contact methods such as email, live chat, or messaging systems to ensure individuals with hearing or vision impairments can communicate comfortably and independently.
- ARIA Labels
Accessible Rich Internet Applications (ARIA) labels provide additional descriptive information for interactive elements such as icons, buttons, and form fields. These labels help screen readers and Braille displays communicate visual interface elements more effectively to users with visual impairments.
- Flexible Text and Readable Fonts
Accessible websites should allow users to adjust text size and browser display settings without disrupting functionality. Readable fonts, scalable text, and adaptable layouts help users with low vision navigate content more comfortably. Ideally, text should remain fully usable when enlarged up to 200% of its default size.
- Clear Language for ASL Users
Content written in plain, straightforward language is easier to understand for individuals who use American Sign Language (ASL) as their primary language. Since sign languages have unique grammar structures, websites should avoid slang, overly complex wording, and ambiguous expressions. Using active voice, consistent terminology, headings, and bullet points can significantly improve comprehension and accessibility.
Benefits of Deaf Blindness Accessibility
Although people with deafblindness accounts relatively small portion of the disability community, organizations and web developers should recognize that compliance with WCAG standards improves accessibility for individuals across a broad spectrum of disabilities, including visual, auditory, cognitive, and motor impairments. People with disabilities account for nearly one-quarter of the U.S. population, with the Centers for Disease Control and Prevention reporting that approximately 1 in 4 Americans lives with some form of disability. When websites are designed to be accessible, businesses often benefit from improved user engagement, longer browsing sessions, and increased audience reach.
Civil Rights & Accessibility for Deafblind Users
Creating accessible digital experiences is not only a best practice in usability, but also a reflection of ethical business conduct and strong commitment to DEI (Diversity, Equity, and Inclusion) principles. The Americans with Disabilities Act of 1990 (ADA), enacted in 1990, protects the rights of individuals with disabilities by ensuring equal access and opportunity while banning discrimination based on disability.
According to the United States Department of Justice, these protections extend to digital environments, including websites and online services. Maintaining an accessible website not only supports the rights and inclusion of disabled users but can also help organizations reduce legal risks, avoid accessibility-related complaints, and minimize the likelihood of costly litigation.
