Extensive research has been carried out into the effect
computers have on eyes and there is no evidence to suggest
that VDUs cause disease or permanent damage. However, some
students may experience discomfort if working on a computer
uninterrupted for a long period of time. Problems may be
avoided by:
- altering the position of the VDU or chair;
- adjusting brightness and contrast levels;
- taking 'micro breaks' (to relax muscles and look away
from the screen).
Students will naturally take breaks away from the computer
screen when using the work booklets. If you feel any of
your students need additional periods away from the screen,
these may be introduced at your discretion, provided that
the total length of time allowed for the test is adhered
to.
