1. How many people in the UK are experiencing sight loss?

Almost 2 million people in the UK live with sight loss (1 in 30). Of these, 360,000 are registered with their local authority as blind or partially sighted. They have experienced some degree of irreversible sight loss, which glasses or contact lenses cannot correct. (Source: NHS)

The number of people with sight loss is set to increase dramatically, growing to 2.7m by 2030 and could double to 4m by 2050 due to an ageing population and the growing incidence of long-term conditions that cause sight loss, including obesity and diabetes.

2. Assistive technology for visual impairments and sight loss

Increasingly, assistive technology comes as standard with the devices you have on your desk or in your pocket.

Tech giants including Apple, Google and Microsoft are working hard to make devices accessible to all. So, you can adjust desktop computers, tablets, and smartphones to make them more accessible if you have sight loss and visual impairments.

In addition, you can buy add-on hardware and software to make devices easier to use.

3. Assistive technology in tablets and smartphones

Intelligent personal assistants – like Siri and the Google Assistant – are a key feature of all modern tablets and smartphones. You can simply ‘ask’ the assistants to carry out tasks including answering queries, sending messages and emails, adding events to your calendar, taking notes and setting reminders.

iOS (Apple) devices include a screen reader called VoiceOver, and a magnifier called Zoom; the latest versions of Android contain a reader called TalkBack.

Combined with the million-plus apps now available for iOS, Android and other mobile devices, such innovations are helping to transform education, work, and leisure opportunities for people with a visual impairment.

Many blind or partially-sighted people now use their smartphone more than any other computing device – with it offering a relatively low-cost and completely mobile solution to many of their requirements.

4. Standalone screen readers for blind or low vision computer users

New computers, and most smartphones, have a screen reader: Narrator, for Windows, and VoiceOver for Apple Mac (also on iPad and iPhone). There’s also a range of specialist screen readers available for people who are blind:

JAWS (Job Access With Speech)

A popular, inexpensive screen reader providing text-to-speech and Braille output for a wide range of computer applications on Windows computers, including the most popular - Microsoft Office, Internet Explorer, Firefox and PDF documents. JAWS is also fully compatible with MAGic screen magnification software. Suppliers of JAWS include Adapt-IT, Keytools, RNIB, and Sight and Sound Technology.

NVDA (Non-Visual Desktop Access)

 A FREE alternative to JAWS. Hear the text on screen being read or have it converted into Braille on a compatible display. Users report that while it works extremely well with web browsers, it can be more problematic dealing with Office applications.

5. Screen magnification for low vision users

For those with low vision, investing in a larger screen is worth considering. There are also ways of magnifying on-screen information within operating systems and programmes.

How to adjust a web browser for low vision

You can adjust your web browser in several ways: zoom in and make text bigger (select View from the main menu). Popular browsers also allow you to adjust colour settings or to turn on a Reader mode and remove visual clutter.

Operating system accessibility options

People with low vision will benefit from the ‘Accessibility’ options in Windows and macOS to increase the display size of text, menus, folders, icons, and the mouse pointer. The high resolution will mean that even zoomed-in, the screen's contents should remain sharp and clear.

Many people with impaired vision can see some colour combinations (such as white text on a black background) better than others. Different colour options are available in most programmes. The majority of computer, tablet and smartphone operating systems have a wide range of pre-defined colour schemes to choose from, or you can create your own.

Zooming in

Zooming increases the size of whatever is displayed in the document window, and many programmes include easy-to-use options to achieve.

  • On a Windows computer: Press the “Ctrl” key, use the wheel on your mouse, or slide two fingers together down the mousepad to zoom in and out.
  • On an Apple computer: Place two fingers on the trackpad and opening out (like a pinch in reverse).

However, there are other options if these shortcuts are not practical for you. Zooming in does not affect the size in which the document is printed out.

6. Specialist screen magnification programmes

Specialist magnification software programmes enlarge and enhance everything on your computer screen. As the size of the enlargement increases, the amount of the original screen image being displayed reduces – but you can use the mouse (or cursor) to select where you want to focus. Many programmes also include options for enhancing and customising screen colours and pointers.

Specialist software options for Windows computers are ZoomText Magnifier Reader, Dolphin Supernova Magnifier and Screen Reader.

Compatible keyboards are also available for Dolphin. These include dedicated function keys for operating the programmes’ most used features. Dolphin Supernova also provides full Braille support for blind users and is compatible with the latest Braille displays.

Specialist solutions for Mac users are ZoomText Mac and MagniLink iMax.

Suppliers of integrated magnification and reading software include Adapt-IT; Inclusive Technology; Professional Vision Services; RNIB,  Sight and Sound Technology.and Thriver

7. Adaptive hardware for people with low vision or who are blind

For those with vision impairment, alternative keyboards can be a big help. There are several different options:

High visibility keyboards

The letters on a standard computer keyboard are small and can be hard to see. A simple alternative option is to purchase a high contrast keyboard or modify the keys on your existing keyboard by covering them with high contrast stickers. These use larger letters and come in upper- and lower-case sets.

Larger keys

People with impaired vision who are learning to type often find it difficult to locate keys accurately on a standard-sized keyboard. It can be much easier for many to use a high-visibility keyboard with a smaller number of larger keys – such as the BigKeys, Jumbo, XL or KeyMonster keyboards.

TechSilver lists seven of the best keyboards for visual impairment.

Specialist keyboards

Some keyboards have been designed specifically to work with specialist software programmes to assist people with visual impairment.

These include Dolphin Large Print, The Jumbo Keyboard from Inclusive Technology, which features large print, high contrast keys – many of which give quick access to the associated software's most useful features.

Chording keyboards

Chording keyboards like the CyKey are another important option, especially for people with more limited dexterity. This is because they only require you to press a few keys in combination (like a chord on the piano) to generate letters. 

8. Braille Displays

Another option for blind users is a Braille display. Although these can be very expensive, they serve a dual function. Utilising just a few keys, Braille displays allow you to enter data and control your computer and to read documents, web pages and email using Braille.

9. Touch-typing skills for inputting data

Using a keyboard is often faster than using a mouse, and for people with little or no vision, it can be the most practical way to input data and interact with a device. In addition, working with keyboard shortcuts or ‘hotkeys’ is an effective and efficient method for anyone to control a computer (more about hotkeys at My Computer My Way).

Learning to touch type

There are many software programmes available aimed at helping people with sight loss learn how to touch type.

Dedicated reading machines will read out printed documents using a synthetic voice. They use a scanner or a camera with optical character recognition (OCR) software to convert printed materials into electronic text that can, in turn, be either displayed on a screen, or read out by a screen reader, or both.

10. Reading machines for printed materials

There are three main types of reading machines:

  • Standalone devices – combine a camera/scanner, OCR software, screen reader and/or monitor in a single device. They are easy (but not very flexible) to use and can be very expensive.
  • Computer-based devices – connect a camera/scanner and OCR software to your computer, allowing you to take advantage of your existing screen display options, as well as utilising screen reading.
  • Portable devices –are lightweight and easy to use on the move.

Suppliers include Adapt-it; Enabling Technology; Humanware; Sight and Sound Technology; and VisionAid.

Many apps run on standard smartphones and tablets that will provide very similar functionality to the above specialist options and are much cheaper if you already own a smartphone or tablet (see below for more details).

11. Video magnifiers

Video magnifiers (or closed-circuit televisions – CCTVs) connect a high definition camera to a monitor display. This allows you to magnify different types of printed documents or handwritten text to a high level.

You can read and navigate your document by moving it around on the table below the camera.

There are three different types of video magnifiers:

  • Desktop video magnifiers – have the highest degree of magnification and often allow you to adjust the text and background display colours.
  • Portable video magnifiers – can either be standalone devices or connect to a laptop computer, utilising software on the laptop to control the display, use OCR, or capture and store images of printed text. Some magnifiers enable distance viewing – for example, presentations.
  • Pocket video magnifiers – are small enough to use on the go for reading a wide range of everyday materials, including documents, letters, bills, menus, timetables and instructions etc. Typical features include the ability to take a snapshot of something that can subsequently be magnified, rather than having to hover with the magnifier in place.

The distinction between reading machines and video magnifiers has significantly reduced in recent years, with many video magnifiers now also including the option to hear documents and read aloud.

Suppliers include Adapt-it; Enabling Technology; Humanware; RNIB; Sight and Sound Technology; and VisionAid.

Please note that many apps run on standard smartphones that will provide similar functionality to the above specialist options. These apps make use of the camera on the phone to scan the page and will use text-to-speech to read it out. For example, Microsoft’s “Seeing AI” is a free app that provides useful features for blind or low-vision users, including a text reader.

It can also identify objects in pictures and recognise handwriting. Currently, Seeing AI is only available on Apple’s iPhones and iPads.

12. Notetakers

Notetakers are small computers designed for use by the visually impaired. They can either have a standard or Braille keyboard, with information being either read out, displayed in Braille or both.

Braille notetakers are portable devices, including email and internet capabilities, a calendar, and an address book. They can usually be connected to a computer or a printer for transferring information, and some can print to a Braille embosser. Notetakers also enjoy a shorter start-up time and a much longer battery life than conventional computers. They are, however, significantly more expensive in most cases and far more limited in the apps and functions they can include.

Suppliers include Humanware, Sight and Sound Technology, and VisionAid.

13. Useful apps for people with low vision or who are blind

It is only possible here to point to a few of the apps available from the App Store (for iOS devices) and/or Google Play (for Android devices). For more comprehensive information and reviews about specialist apps for the iPad and iPhone, visit the AppleVis website for blind and low-vision users at www.applevis.com

Blind and partially sighted people have found the following apps to be particularly useful:

Seeing AI

A free app (iOS only) provides features such as face and object recognition, international currency identification, text and handwriting recognition and a barcode scanner for product identification.

Be My Eyes

14. Guidance for employers and employees

It's important to recognise that there are adaptations your employer should make if you're working and experiencing sight loss. Training can also help people adjust to using technology if they have low vision or are blind. 

What should employers do?

Under the Equality Act, employers have a duty to ensure that employees with a disability (including visual impairment) can perform effectively.

To meet the requirements of the Equality Act, employers may need to make ‘reasonable adjustments to ensure that disabled members of staff have equal access to everything involved in doing and keeping their job as any non-disabled colleague. Employers who fail to meet their responsibilities under the Act may be vulnerable to discrimination claims and could be taken to an employment tribunal.

Any adjustments required do not necessarily need to cost a lot of money and depend partly on the size and nature of the organisation. For blind or partially sighted employees, reasonable adjustments could include:

• adapting the workplace

• introducing some changes to the work organisation

• providing personal training and support

• making use of relevant assistive technologies.

Advances in technology mean that anyone who is losing, or who has already lost, their sight can now overcome many of the barriers previously faced and continue to be a highly productive employee. Government schemes like ‘Access to Work’ can also help meet some of the additional employment costs.

Training for employees and students with sight loss

Students, employees and other users will only realise the full potential of some of the solutions outlined in this factsheet if they receive adequate training and have sufficient opportunity to become familiar and proficient with the products.

Training is most effective when it is spread over time and geared towards the individual, focusing on their particular tasks, abilities and challenges. Periodic training helps users to practice and consolidate new skills between sessions.

A wide range of private and voluntary organisations offer computer training services (some training costs). In addition, many specialist suppliers and software producers provide online guidance and tutorials about how to get the most from their products. There is also a wealth of free training resources available online, including on YouTube.

Useful tutorials, guides and reviews about assistive technology for people with sight loss are available from:
