Minor visual impairment

You have a visual impairment but you can see a little. In most cases you may have problems with contrasts or text size. Visual difficulties can also develop as you get older.

You may come across some of the following barriers if web pages are not accessible:

  • Insufficient contrast between what is displayed on the page and the page background, making it difficult to read the content.
  • Small text size, and if you apply the browser zoom feature, the content overlaps or falls off the page, making it difficult to read.
  • Some elements on the web page cannot be configured to suit your needs (for example, text images or the fact that there is no clear separation between the page content and its format or design).

People with colour blindness, (for example Daltonism) can find it impossible to understand information conveyed only in colour, such as a bar chart in various colours.

To navigate around web pages more comfortably, you can get a larger screen or use a screen magnifier.

The following table shows you how to change the size of web page content in the most commonly-used browsers.

Browser Menu options
Mozilla Firefox

View > Size > Increase

(Key combination Control and the + key) 

Internet Explorer

View > Zoom > Increase

Google Chrome

View > Zoom in

(Key combination Control and the + key)

Opera

Page > Scale > %

Safari

Below we show you how to change colours, styles and fonts of pages in your browser depending on your needs or preferences:

Browser Menu options
Mozilla Firefox

Tools > Options > Content

Internet Explorer

Tools > Internet options > Button "Accessibility" in the "General" tab > Activate one of the "Omit... " boxes and then go to the "General" tab to personalise

Google Chrome

Configuration > Link to "Show advanced options" > Section "Web content" > Button "Personalise fonts... "

Opera

Configuration > Options > Tab "Web pages"

You can configure your computer to high contrast:

  • In Windows, with the key combination Shift or Caps + Alt + print screen key or go to Control Panel, then Activity Centre and you can set the high contrast there.
  • In Mac OS, go to Accessibility and the "Screen" section, then activate the "Invert colours" box.
  • In Linux Gnome, go to Systems, then to Preferences and then to Appearance, and select one of the high contrast areas.
