什么是 HEV Light
高能可见光(HEV)或蓝光,是指光谱中的一个特定波长范围。 電磁頻譜通常在 380 到 500 纳米之间。它的特点是呈蓝紫色,位于 紫外线辐射 在 光譜.
HEV 光既来自太阳等自然光源,也来自 LED 灯、电脑屏幕和数码电子设备等人造光源。虽然紫外线辐射对眼睛和皮肤的潜在危害早已得到公认,但 HEV 光的重要性最初却被忽视了。然而,最近的研究揭示了高紫外线照射的潜在负面影响。
过度暴露于高紫外光,尤其是来自人造光源的高紫外光,与各种眼部疾病和不适有关。它与白内障和视网膜疾病(如黄斑变性)的风险增加有关。此外,长时间暴露在蓝光下会导致视觉疲劳、数码眼疲劳和昼夜节律紊乱,从而影响睡眠模式。
