Vision aids

Find out about the many techniques and tools you can use, if you are blind or have sight loss, to make your everyday life easier, from use of lighting and traditional hand-held devices to more high-tech solutions.

On this page, we’ll going to cover:

If you have vision impairment, the way you light your home and workplace can improve things greatly and help you to live more independently.

So, think about the areas you use most and how best to light them:

  • Keep windows clear of plants.
  • Use blinds to control the direction of light and strong sunlight.
  • Arrange your seating to make the best of natural light from windows.
  • Use shades and dimmers switches to reduce glare.
  • Use daylight bulbs in rooms with less natural light. You can use these for specific areas of a room.
  • Use timers to light certain areas automatically at specific times, e.g. set your bedroom light to switch on ten minutes before you go to bed, or your hallway and living room lights for ten minutes before you get home.
  • If you are less mobile, you can use a remote control, your smartphone or other smart home devices to control your lighting.
  • Avoid shiny, high-gloss kitchen units or other furniture, as light can bounce off these and distract you.

Task lighting

Use task lights, such as adjustable lamps, for activities such as reading and writing.

The best position for an adjustable lamp is below your eye level, between you and what you want to look at.

This reduces the amount of glare you experience when doing close work. It also makes tasks such as reading less tiring.

Also, ideally, you want to be able to adjust the lamp to any height, and move the head freely, sideways and up and down.


Magnifiers are helpful if you have low vision, because they simply make things bigger.

Depending on what you need, there are a number of types on the market:

  • Handheld magnifiers – fairly cheap, easy to carry in a pocket or bag, and handy for reading labels, menus or short letters.
  • Illuminated hand magnifiers.
  • Handsfree magnifiers – wearable, like glasses.
  • Electronic magnifiers – with video screens.
  • Stand magnifiers – useful for larger blocks of text, documents or anything you need to look at for a long time.
  • Illuminated stand magnifiers.
  • Line magnifiers – these have a coloured line across them to help you to scan text more easily and are good for longer pieces of text.
  • Folding magnifiers – small and easily carried around.
  • Bar and brightfield magnifiers – provide magnification and a large visual field.
  • Technical magnifiers – for close extended tasks, such as quality control or hobbies such as viewing stamps, coins or insects.
  • Mini telescope (monocular magnifier) – can be focused on objects, in some cases as close as 1m and beyond as far as needed.
  • Compact binoculars – these can be useful if you’re partially sighted with useable sight in both eyes.

You can find out more about the types of magnifiers available from Associated Optical, Magnifico, Optima Low Vision Services, Vital Tech, RNIB’s online shop and other online suppliers.

You can also use:

  • Smartphones’ built-in magnification ­– for occasional use only.
  • Screen reader – also, occasionally, you can use your smartphone to take a photo of some text and use a screen reader to read it.

Top tips for using magnifiers:

  • One magnifier cannot solve all your problems: you may need a hand magnifier when you’re out and about, and a stand magnifier at home.
  • The higher the magnification, the smaller the lens, so the closer you need to hold it to your eye.
  • If you hold a magnifier too far away from your eye, the image will be upside down.
  • If you can, shine a lamp directly onto what you are looking at.
  • Hold the magnifier close to your eye and bring what you want to see up to the magnifier.
  • Magnifiers usually work best with spectacles:
    • For close work, use your reading spectacles.
    • For distance, use your distance spectacles.
  • If you use a magnifier to make print bigger you can often only see one or two words or letters at a time. To keep your place:
    • Use your finger to mark each line.
    • As you finish a line, return your finger to the beginning of the line and then drop it down to the next line.
  • If it’s easier, move the book or page from side to side, not the magnifier.
  • When reading in a chair, put your book or newspaper on a clipboard to keep the page flat and still.  Use a cushion or tray for support.
  • Keep your magnifier clean with the lens cloth provided.
  • If your eyes get tired, take a break and start again later.

Get a low-vision assessment first

Before you choose or buy a magnifier of any kind, you should have a professional low-vision assessment.

You can get a free NHS assessment through your local hospital eye clinic. Speak first to your GP, optometrist or ophthalmologist for a referral for an appointment.

At the assessment, a qualified low-vision practitioner will check your vision and decide whether low-vision aids such as magnifiers are right for you.

If they do recommended a magnifier, or magnifiers, you can get them free of charge on the NHS.

They may recommend different magnifiers for different tasks. Always follow their advice.

Magnifiers can be difficult to use at first, so low-vision professionals will help you to get the best out of the equipment they prescribe.

If you have problems using any of your magnifiers, get in touch with your GP, optometrist or ophthalmologist.

Screen readers

If you are blind or have very limited vision, screen readers can help you to use digital technology to explore the internet and use apps.

Nearly all computers, tablets and smartphones now have built-in screen readers.

How do screen readers work? 

Screen readers read out loud what’s on the screen you’re looking at. Some screen readers also work with braille displays.

You can adapt them to suit your needs, e.g. by changing the language and speed.

When you’re starting out with a screen reader, you’ll need to learn some shortcut keys or touch gestures.

With time and practice, you can learn the more advanced features. You might also want to get some training.

Find out more about home support and training from AbilityNet.
