The advice given here will help you feel confident about guiding a person with sight loss: Always offer assistance first, not everyone will need help
Introduce yourself – ask the person where they want to go and how they wish to be guided
Ensure you are one step ahead of the person you are guiding
Give instructions where necessary but don’t overdo it
Be aware of hazards at ground level and at head height
When guiding, give information about the people who are present and the environment as you move around
