利用脑波讯号做双眼不等视配镜优化

Measurement of Anisometropia with Brain Waves

屈光参差(Anisometropia)是用眼习惯引起晶体调节力与眼肌内聚力不同,因聚焦造成视网膜上影像清晰度程度不同所致。本研究利用脑波讯号与视觉生理反应之间的关系,量测视觉清楚与模糊的脑波讯号变化,分析脑波专注与放松曲线作为不等视配镜进行优化。双眼视差−2.50 D的受检者在配镜与验光时,分别使用脑波量测、Worth4-dot视标法及视标红绿分离法检测。配戴−1.50 D眼镜时,三项测试数据趋向实验设定的期望值,受检者获得很好的融像(Fusion)及立体视觉(Stereopsis),最适合的配镜处方。本创新方法利用脑波讯号检测视觉不等视(anisometropia),无需经由受检者主动感受反应,由脑波之专注与放松曲线经判别即可获得最佳验光与配镜数据,并与其它两种方法具一致性,证实脑波辅助不等视验光技术为可行。

Anisometropia is caused by the difference of crystal lens accommodation and ocular muscle cohesion caused by eye habit. It is caused by the difference in the sharpness of the image on the retina caused by focusing. In this study, the relationship between brain wave signals and visual physiological response was used to measure the changes of brain wave signal with clear and blurred vision, and concentration and relaxation curves of brain wave was analyzed as optimize anisometropia prescriptions. When the anisometropia −2.50 D subject is equipped with spectacles, brainwave measurement, worth4-dot visual standard method, and visual standard red-green test are used to perform the refraction and ophthalmic dispensing of anisometropia. According to three method’s test data, when the anisometropia −2.50 D subject wears −1.50 D glasses, the fusion, stereo vision and anisometropia correction effects are the most suitable prescriptions for the subject. This innovative method uses brainwave signals to detect anisometropia. It does not require the subject to actively feel the response. From the brainwave attention and meditation curve can be discriminated to obtain the best prescriptions data. The experimental results also meet the original expectations, which prove that the brainwave assisted optometry technology is feasible.
