Question 3

Which lens is used to correct myopia (short-sightedness)?

Question 4

Which statement accurately describes eye at a GCSE level?

Exam Tip

Short-sighted people can see things close up but struggle with distance; long-sighted is the opposite.

The fastest way to improve your grade is to practise exam-style questions, identify your gaps, and focus only on what you don't know.
