2. Describe how the lens works
- The lens works by focusing on what you want to look at and directing it to the back of your eye. It works along side the cornea

3. Why do we squint when exposed to bright light
-We squint because there is to much light coming into our eye for the pupil to take ( I think this is because the pupil can not get any smaller so we squint to stop to much light coming in).

4. Which parts of the eye are involved in focusing?
- The parts of your eyes that are involed in focusing are lens, cornea and iris.

5. Discuss the implications of losing one eye? -Losing an eye effects you alot. Firstly it would be harder to see things without a joint perspective of two eyes and secondly it would also effect you when you wanted to play a sport such as tennis because it would be harder to know where the ball is and not hit close enough = STUDENT TASK FOUR = = Criket =
