The optometric intervention demonstrates significant reduction of visual discomfort in both intervention groups. The effect is supported by the improvement that can be observed in the control group after the lighting intervention in this group. Combined ergonomic, lighting and optometric intervention gives the best total effect. The final results will be given at the conference.
