Accuracy of ocular pulse frequency by contact lens sensor in relation to heart rate interval.

Abbreviations: CI = confidence interval; OPF = ocular pulse frequencyAccuracy of ocular pulse frequency by contact lens sensor in relation to heart rate interval.缩写说明：CI即置信区间（confidence interval）；OPF即眼脉冲频率（ocular pulse frequency）。通过隐形眼镜传感器（contact lens sensor）测得的眼脉冲频率，与心率间期的对应准确度。
