For many of us, routine internet browsing is something we take for granted. Everything from checking email to shopping and even working from home can seem effortless. But for millions of blind and low vision users, these same digital experiences fail to work as promised, hampering productivity and creating frustration. Despite the ubiquity of online connections, many websites, applications, and services fail to meet the needs of people with disabilities. For organizations working toward WCAG, Section 508, or ADA compliance, understanding how assistive technologies (AT) interact with your digital experiences is foundational. When websites and apps are built to work seamlessly with screen readers and magnifiers, accessibility stops being an abstract mandate and becomes a measurable, brand benefit. That compatibility not only reduces compliance risk, it also demonstrates a commitment to inclusive user experiences — something audit teams, procurement, and end users will notice.

What is digital accessibility compliance?

Digital accessibility compliance refers to meeting established standards that require digital products to be usable by people with disabilities. Often, organizations must conform to multiple standards, such as WCAG, ADA, Section 508, EN 301 549, EAA, and others. In practice, this means that your organization’s web pages, applications, documents, and platforms must work with AT and avoid common pitfalls associated with nonconformance. There are multiple, measurable criteria: providing text alternatives, enabling keyboard navigation, ensuring screen reader compatibility, using sufficient color contrast, and building interfaces that hold up under real-world use. Organizations that invest in digital accessibility mitigate legal risks, reduce support burdens, and expand market reach by creating experiences that more people can actually use.

How digital accessibility has become a requirement for businesses

Having a digital presence is no longer optional; it’s the baseline for participating in today’s economy. Digital experiences shape how people shop, learn, work, and access essential services. When those experiences are inaccessible, a significant segment of the population is effectively shut out. For people with disabilities, this creates inequity in access to digital services. For businesses, there’s a very real financial impact of exclusion: research estimates that inaccessible e-commerce experiences cost more than $6.9 billion in lost sales yearly, largely because customers with disabilities abandon sites they can’t navigate or use. In short, accessibility has become a fundamental requirement for any truly effective digital strategy.

The legal and ethical imperative

Digital accessibility isn’t optional either; it’s a defined legal requirement in most sectors and an expectation from customers. In the United States, the Americans with Disabilities Act (ADA) has been repeatedly interpreted by courts to apply to websites, mobile apps, and other digital services. Section 508 requires federal agencies and their vendors to meet accessibility standards, and many states have parallel laws. Globally, the Web Content Accessibility Guidelines (WCAG) serve as the de facto benchmark for compliance, referenced in legislation across the EU, Canada, the U.K., and other regions. Failing to meet these standards exposes organizations to legal risk, including lawsuits, settlements, and procurement barriers. Meeting accessibility requirements is not only about avoiding penalties; it’s a way to demonstrate that your organization is committed to serving every employee and customer equally.

How screen readers translate the digital world

For people who are blind or have low vision, a screen reader is an indispensable tool that enables full participation in the digital world. But how do they work? Screen readers don’t read content the same way sighted users do; instead, they interpret the underlying code. Modern screen readers pull information from the accessibility tree, which is built from the HTML, ARIA attributes, and semantic structure of a webpage or application. This semantic structure allows screen readers to identify key elements like headings, landmarks, lists, buttons, links, and images, and present them with context rather than guessing based on appearance. When a sighted user sees a button, they recognize it visually. A screen reader only knows it’s a button if the developer has correctly labeled it as one, enabling it to announce “Submit, button” and letting the user activate it with keyboard commands. The same applies to form fields, tables, menus, and dynamic updates—if they’re labeled properly, the screen reader can accurately announce them. This translation makes it possible for blind and low vision users to navigate, understand layouts, complete tasks, and interact with complex interfaces without relying on a mouse or visual cues.

Common screen reader features

Screen readers, such as JAWS, offer a range of capabilities that support efficient navigation for blind and low vision users.

  • Flexible Reading Controls: Users can read content continuously or move through it by sentence, word, or character. This precision is essential for tasks like editing documents, reviewing data, or checking the accuracy of typed text.
  • Structured Navigation: Keyboard commands allow users to jump directly to headings, regions, links, form fields, tables, lists, and other key elements. JAWS also provides features such as the Virtual HTML Viewer and element lists, which let users scan a page’s structure without wading through every line of content.
  • Element Context and Feedback: Screen readers announce both the type and state of elements, i.e., heading level 2, button, checkbox checked, or menu collapsed. This enables users to understand how the interface is structured, how components behave, and which actions are available at any given time.
  • Form Interaction and Error Handling: A well-coded form is fully usable with speech and keyboard shortcuts. Screen readers announce labels, required fields, input types, and validation errors, allowing users to complete tasks independently.
  • Braille Support: Screen readers can output information to refreshable braille displays, giving users tactile access to text, structure, and even formatting. When content is marked up semantically, screen readers can expose clear, accurate braille characters to a user’s display, ensuring the information is both reliable and efficient to read.

For organizations, these features highlight the importance of accessible code and good, semantic structures. Improper heading structures, unlabeled links, and missing alt text can disrupt the experience for screen reader users, preventing users from accessing information and completing tasks. When your digital assets are built to work well with screen readers, you’re also meeting many of the core expectations central to key accessibility standards. Good structure is good compliance.

Screen magnifiers as visual navigators

While screen readers address the needs of those with significant vision loss, magnifiers cater to a broader spectrum of visual impairments. Screen magnifiers enlarge a portion of the computer screen, but with far greater sophistication and flexibility. For people with low vision, magnifiers are crucial tools that transform small text and graphics into perceivable content.

How screen magnifiers offer granular control

Screen magnification software like ZoomText provides far more precision and flexibility than a basic browser zoom, which often reflows content unpredictably or distorts layout. Instead, screen magnifiers offer precise control over how much and which portion of the screen is enlarged, alongside other enhancements.

  • Flexible Magnification Views: Users can magnify the entire screen, a movable lens area, or a docked region that enlarges only part of the display while keeping the rest at standard size.
  • Adjustable Magnification Levels: Users can choose from a wide range of magnification increments, from subtle enlargement to very high levels.
  • Color and Contrast Enhancements: Color filters and contrast settings that help reduce glare, improve readability, and increase differentiation between text and background.
  • Font Smoothing and Improved Clarity: Smoothing features ensure that magnified text maintains clear edges and readable shapes, rather than becoming blocky or pixelated as magnification increases.
  • Enhanced Tracking: Pointer, cursor, and focus tracking that follows a user’s mouse movements helps eliminate the guesswork that can occur when magnification moves parts of the interface out of view.

Design considerations for screen magnifiers

Designing for screen magnifier users is fundamentally about preserving usability as content grows larger, becomes more focused, or is more visually customized. When a user is viewing your site at high magnification, whether in full-screen, lens, or docked mode, small design flaws can turn into large-scale issues.  Many of these considerations align directly with WCAG requirements and ADA expectations for usable content at higher zoom levels:

  • Responsive Layouts Matter: Content must reflow cleanly as the user increases magnification. If text overlaps, elements disappear, or horizontal scrolling becomes unavoidable at higher zoom levels, the experience becomes difficult or impossible to follow for magnifier users.
  • Clear Visual Hierarchy: Headings, paragraphs, lists, and groupings must remain understandable even when enlarged. A strong hierarchy helps users maintain orientation when only a portion of the screen is visible at a time.
  • High Contrast and Color Flexibility: Meeting WCAG contrast ratios is only the baseline. Many low-vision users apply high-contrast or custom color filters, and your design must remain readable under those conditions.
  • Avoid Fixed-Size Components: Rigid pixel-based widths or heights often fail under magnification, causing clipping or forcing users to hunt across the page. Flexible, fluid layouts ensure consistent usability across zoom levels.
  • Reliable Focus Indicators: Keyboard focus must always be visible and trackable. When a user navigates with the keyboard at high magnification, the magnifier needs a clear and logical target to follow.
  • Don’t Use Color Alone: High magnification and color adjustment filters can distort or eliminate color cues. Always pair color with text, patterns, icons, or labels.

By keeping these considerations in mind, you ensure that your digital content remains accessible and delivers consistent usability across a wide range of visual needs.

How screen readers and magnifiers complement each other

While screen readers and magnifiers serve different needs, they are not mutually exclusive; in fact, they often work in tandem, creating a unified approach to accessibility.

A unified approach to inclusive design

Vision loss varies widely from person to person. Some individuals progress to complete blindness, while others retain some vision. For some users with low vision, a magnifier is sufficient, while others may opt to use both a magnifier and a screen reader simultaneously to reduce eye strain and mental fatigue. Many users operate in both worlds, pairing magnification with speech to maintain speed and reduce strain over long work sessions.

How screen readers and magnifiers work together

When designing for digital accessibility, a common mistake is treating screen readers and magnifiers as separate use cases. The reality is that many low vision users depend on both, sometimes simultaneously. Magnification provides visual context and spatial awareness, while speech offers speed, efficiency, and relief from eye strain during longer tasks. Combined tools like Fusion exist for exactly this reason: giving users the flexibility to shift between modalities based on their needs. For organizations, this means your digital experience must support multiple modes of access simultaneously. Clear structure, reliable labeling, strong contrast, and predictable navigation patterns benefit users who are zooming in visually, navigating by keyboard, listening to text-to-speech output, or mixing all three approaches. When your digital experience is designed with digital accessibility in mind, these tools complement each other naturally.

Building an accessible digital ecosystem

Building an accessible digital ecosystem, one that meets compliance requirements and elevates your brand, requires proactively structuring your content and code so that it works reliably with AT.

Digital content is the backbone of accessibility

Think of your content as a structure with clear rooms, defined hallways, and labeled doors. That means using proper headings, ordered or unordered lists, and logical paragraph breaks. Without this structure, a screen reader delivers users little more than a wall of text, making navigation, comprehension, and skimming nearly impossible.

The importance of semantic HTML

Semantic HTML gives assistive tools a universal language. Use <button> instead of a clickable <div>, <nav> for navigation groups, <main> for core content, and <form> for user input areas. Semantic markup ensures that what a sighted user sees as a button or link becomes equally accessible to someone using a screen reader or a magnifier. Non-semantic shortcuts force assistive tools to guess, and when they fail, blind and low vision users are stalled, unable to move forward.

Keyboard navigation

Accessibility is about functionality, how real people interact with your products and services. Every interactive element must be navigable via keyboard (Tab, Enter, arrow keys). Focus should always be visible and manageable. Because many users browse on smartphones, tablets, or even in public on self-service kiosks and touchscreens, the displays need to be large enough and labeled clearly so magnifiers or mobile screen readers can interpret them accurately and consistently..

Real-world testing

Automated accessibility scans catch some issues, but they don’t simulate real user experiences, which can lead to errors and accessibility failures. The 2025 WebAIM Million Report found an average of 51 errors per homepage — even among the web’s most popular sites. While that number represents a 10% decrease from 2024, it still highlights the roadblocks blind and low vision users face when navigating the internet. Robust accessibility testing requires using both AT and the people who rely on these tools. That means working with users—or trusted accessibility experts—to navigate your site with the keyboard alone, listening to your content through a screen reader, and viewing your interface at high magnification to see whether layouts hold up or remain usable at high magnification. Hands-on testing of your digital assets shifts your perspective from how you see it to how others experience it.
