Visual Impairment

1. Introduction and Overview

Visual impairment in higher education ranges from low vision to total blindness, and includes conditions that are stable, progressive, or fluctuating. As with other disabilities, environments and materials are typically built around sighted assumptions — text-heavy slides, image-only documents, visual-only signage — which can exclude students not because of their vision itself, but because of how information and space are designed.

This chapter draws on UK lived-experience research into blind and visually impaired students’ access to and participation in higher education, the Finn persona and associated Accessible Academy guidance, and a detailed barrier-to-solution mapping exercise covering teaching materials, online systems, campus navigation, and assessment.

2. Understanding the Disability

What this covers

• Visual impairment spans a spectrum from low vision (some useful sight, often supported by magnification) to total blindness, and can be present from birth or acquired later in life.
• Some conditions are stable, others are progressive or fluctuate, which affects how consistently a student can rely on a given level of vision.
• Students use a range of methods to access information: screen readers, Braille, magnification, audio, and large print, often in combination.

Common misconceptions

• That all visually impaired students use, want, or benefit from the same equipment: research found students being given equipment (such as a computer mouse, or a Braille display before they had learned Braille) that did not match their actual needs, simply because it was standard issue.
• That a student’s own assessment of what they can or cannot do should be second-guessed by staff: lived-experience research documents students having their competence directly questioned by staff, including in contexts as significant as career guidance.
• That accessibility support, once assessed and arranged, will reliably be delivered: research found repeated cases of agreed adjustments (accessible exam formats, extra time) simply not being provided.
• That visual impairment only affects reading: it also affects orientation and navigation, participation in visual or diagrammatic content, and independent use of digital systems.

3. Common Challenges in Higher Education

• Materials and systems designed around sighted use by default: inaccessible PDFs, uncaptioned media, and visual-only signage.
• A significant, often invisible administrative burden falls on the student to identify, request, and chase up adjustments, rather than these being embedded as standard practice.
• Support that is assessed generically rather than matched to the individual — leading to unused, mismatched equipment and wasted assessment time.
• Attitudinal barriers, including staff doubting a student’s own judgement of their capabilities, which research found could affect decisions as significant as career and course choice.
• Agreed adjustments (accessible exam formats, extra time) not always reliably delivered in practice, even once formally arranged.
• Time and energy spent managing access barriers can reduce a student’s capacity to take part in work experience, societies, and other activities important for future employability.

5. Inclusive Teaching Strategies

Before class

• Provide materials in accessible formats: tagged, structured, searchable documents rather than scanned images.
• Use structured headings in Word/PDF documents so screen readers can navigate them properly.
• Add meaningful alternative text to every image, and check colour contrast before sharing materials.

During lectures

• Verbally describe visuals, diagrams, and any information conveyed only through a slide.
• Read aloud key written information rather than assuming it will be seen.
• Share detailed lecture notes and structure in advance of the session.
• Allow and support audio recording of lectures.

Group work

• Ensure any shared visual materials (diagrams, whiteboard notes) are also described or provided in an accessible format to the whole group.

Practical sessions

• Describe physical layouts and materials verbally, and check equipment and fieldwork settings for accessibility in advance.

Online learning

• Ensure all interactive online features support clean keyboard navigation, not only mouse or touch input.
• Caption video content and provide full text transcripts.

Assessment

• Offer accessible digital assessment formats and confirm agreed adjustments (extra time, compatible platforms) are actually in place well before the assessment date.

6. Classroom Accommodations

• Materials provided in accessible, structured formats ahead of each session, not adapted only on request after a problem arises.
• Individually matched equipment and support, confirmed directly with the student rather than issued as a generic package.
• Permission and support for audio recording of lectures.
• Preferential seating where relevant for any residual vision or use of assistive devices.
• A named contact for the student to flag inaccessible materials or systems quickly, with a fast turnaround for fixing them.

8. Communication Guidelines

9. Environmental Adjustments

• Consistent, predictable physical layouts, with advance notice of any changes to rooms or routes.
• Tactile and audio wayfinding cues supplementing visual-only signage around campus.
• Good, even lighting and strong colour contrast in signage and printed materials.
• Clear, decluttered pathways, particularly in corridors and shared spaces.
• Quiet spaces available where concentrating on audio information (screen readers, recordings) is easier.

11. Real-Life Example / Case Study

Case Study: A student navigating a locked-format exam paper

Malika (a composite, illustrative example) is registered blind and uses a screen reader. Her disability support assessment agreed extra time and a screen-reader-compatible exam format at the start of the year. In her first-semester exam, the paper is distributed as a locked, image-only PDF that her screen reader cannot read, and the invigilator is not aware any adjustment had been agreed.

Poor practice

• An agreed adjustment is not communicated to the people actually delivering the exam.
• The exam paper itself is produced in a format that is inherently inaccessible, regardless of any individual adjustment.

Inclusive practice

• Exam papers are generated as accessible, structured, searchable documents by default, for every assessment, not adapted only when a request is received.
• A checklist confirms agreed adjustments have reached everyone responsible for delivering the assessment, with the student able to confirm this in advance.
• A fast-response contact is available on the day in case a problem is discovered too late to have been caught beforehand.

Lessons learned

• An adjustment being ‘agreed’ on paper does not guarantee it is delivered — a verification step is needed.
• Building accessible formats into the default exam production process removes the need to rely on individual adjustments working perfectly every time.
