They work out the correct type of spectacles that the person needs, and make sure that they fit correctly. You may want to visit an optician.

  9. Unit 17: Global eye What is the African countryside like? Many countries in Africa have very dry weather, making it difficult to grow crops to earn money. There are also problems with transport, as many people can’t afford to buy cars or use public transport. As a result, many African people don’t have access to a doctor, dentist or optician, or they are unable to afford to go. What problems do you think this causes? Unit 17: Global eye

  10. Unit 17: Global eye How do children in African countries get spectacles? Organisations like Vision Aid Overseas collect spectacles that people no longer want, and send them to countries in Africa for people there to use. They also provide opticians who can advise people on the right glasses to use, and take care of any other sight problems they might have. How do you think supplying people with spectacles could improve their life? Design a poster to encourage people to donate their used spectacles to a charitable organisation Unit 17: Global eye
