Question 1 Report
The table shows causes of eye strain and possible solutions.
| Cause | Preventive measure |
|---|---|
| Staring at screen without breaks | |
| Glare on screen from lighting |
(a) Complete the table by suggesting a preventive measure for each cause. [2]
(b) Explain three additional measures that can be taken to reduce eye strain. [3]
(c) State one further health risk from prolonged computer use other than eye strain or RSI. [1]
Answer Details
(a) The completed table of preventive measures for eye strain:
| Cause | Preventive measure |
|---|---|
| Staring at screen without breaks | Follow the 20-20-20 rule: every 20 minutes, look at an object 20 feet (about 6 metres) away for 20 seconds to relax the eye muscles. [1] |
| Glare on screen from lighting | Use an anti-glare screen filter or reposition the monitor so that windows and overhead lights are not reflected on the screen. [1] |
(b) Three additional measures to reduce eye strain:
- Position the monitor at arm's length from the user and adjust the top of the screen to be at or slightly below eye level, so the user looks slightly downward. [1]
- Adjust the brightness and contrast of the monitor so it is comfortable and matches the ambient lighting in the room, avoiding a screen that is much brighter or darker than the surroundings. [1]
- Have regular eye tests, especially for employees who use a computer for long periods each day, to detect vision changes early. [1]
(c) One further health risk from prolonged computer use (other than eye strain or RSI):
Back pain caused by sitting in a poorly adjusted chair for long periods without proper lumbar support, leading to muscle strain and spinal problems. [1]
