The influence of aging and a couple of external and internal targets on eye accommodation under monocular vision using an infrared optometer were studied. The subjects were 11 healthy adults aged 20-40. In comparison with using internal targets, the amount of accommodative response, tension velocity for accommodation and relaxation velocity for accommodation showed a tendency to increase when using an external target. In particular, these tendencies showed a predominantly in middle-aged subjects. It is suggested that external targets gives some more precise information concerning eye accommodation. In using internal targets, instrument myopia and psycho-physiological factors might bring about a disturbance of reproducibility during eye accommodation.
研究了衰老以及一些外部和内部目标对单眼视觉下使用红外验光仪时眼睛调节的影响。受试者为11名年龄在20至40岁之间的健康成年人。与使用内部目标相比，使用外部目标时调节反应量、调节的张力速度和调节的放松速度有增加的趋势。特别是，这些趋势在中年受试者中表现得尤为明显。这表明外部目标能提供一些关于眼睛调节的更精确信息。在使用内部目标时，器械性近视和心理生理因素可能会在眼睛调节过程中导致重复性的干扰。
