该实验的目的是确定透镜对成功使用者的稳态调节的影响，因为有推测，近调节功能障碍可能是这些患者的一个因素。对6例成功的Irlen患者进行了近模糊刺激（2,3,4 D）的单眼稳态调节评估，采用非滤光眼镜屈光矫正或光谱宽带滤光眼镜屈光矫正。使用哈丁格符合验光仪主观测量调节，两种情况下的平均调节水平无显著差异。此外，滤过处方的调节变异性有小而显著的增加。使用Irlen矫正没有任何积极的影响单眼稳态调节在近。
The purpose of the experiment was to determine the influence of Irlen lenses on steady-state accommodation in successful users, as there is speculation that near accommodative dysfunction may be a factor in these patients. Monocular steady-state accommodation in six successful Irlen patients was assessed for near blur stimuli (2, 3, and 4 D) either with a nonfiltered spectacle refractive correction or their spectrally broad-band filtered spectacle refractive correction. Accommodation was measured subjectively using a Hartinger coincidence optometer, There was no significant difference in mean level of accommodation between the two conditions. Additionally, there was a small but significant increase in accommodative variability with the filtered prescription. The use of the Irlen correction did not have any positive effect on monocular steady-state accommodation at near.
