防藍(lán)光功能護(hù)眼效果有限,科學(xué)用眼習(xí)慣才是保護(hù)視力王道

   時(shí)間:2025-08-28 17:57 來源:ITBEAR作者:陸辰風(fēng)

近期,市場上眾多電腦顯示器、電視機(jī)及學(xué)習(xí)機(jī)等電子設(shè)備紛紛標(biāo)榜其“防藍(lán)光”功能,這一賣點(diǎn)迅速吸引了廣大消費(fèi)者的目光。消費(fèi)者們迫切想要了解,這一功能是否真的如廣告所述,能有效保護(hù)眼睛健康。

國家眼科診斷與治療工程技術(shù)研究中心通過實(shí)驗(yàn)驗(yàn)證,屏幕上的“防藍(lán)光”功能確實(shí)能夠在一定程度上減輕視覺疲勞。這一發(fā)現(xiàn)為那些長時(shí)間面對(duì)電子屏幕的用戶帶來了一絲慰藉。

然而,專家同時(shí)提醒,盡管許多電子設(shè)備內(nèi)置了“防藍(lán)光”技術(shù),但人造光源中的藍(lán)光成分在各類電子屏幕中仍然普遍較高。這意味著,即便設(shè)備具備防藍(lán)光功能,長時(shí)間、近距離地使用電子產(chǎn)品仍然會(huì)對(duì)眼睛健康構(gòu)成潛在威脅。因此,“防藍(lán)光”功能并非解決視覺健康問題的萬能鑰匙。

面對(duì)這一現(xiàn)狀,專家強(qiáng)調(diào)了科學(xué)護(hù)眼的重要性。他們建議,除了依賴“防藍(lán)光”功能外,消費(fèi)者還應(yīng)養(yǎng)成良好的用眼習(xí)慣。例如,每使用屏幕20分鐘后,應(yīng)適當(dāng)遠(yuǎn)離屏幕進(jìn)行遠(yuǎn)眺,以有效緩解眼睛疲勞。

專家還提醒消費(fèi)者,選擇電子設(shè)備時(shí),除了關(guān)注“防藍(lán)光”功能外,還應(yīng)綜合考慮屏幕亮度、對(duì)比度以及色溫等參數(shù),以確保選擇到最適合自己眼睛健康的設(shè)備。
