||The influence of long-term visual near-work on accommodation and vergence - A field study
||June 1994, Vol.23, No.1, p.27-39. 49 ref.
||A study of the influence of sustained, visual near-work on a set of oculomotor functions (ZCSV, Zone of Clear Vision) was carried out in a group of young, female accountants engaged in full-time work using a video display terminal. PRA (Positive Relative Accommodation), NRA (Negative Relative Accommodation), PRC (Positive Relative Convergence) and NRC (Negative Relative Convergence) were measured before work and at the end of the working day. There were significant reductions in the four ZCSV components over the working day; vergence reductions accounted for over 60% of the changes.
