大腦性視障 CVI

講了LED燈的藍光問題已經有七、八年，講到口水都乾了，現在終於見到某著名燈商品牌，生產色温2400K的[防藍光標準]的天花燈，並且用[防藍光]作為招攬生意的手法。
2500K的燈光最黃，藍光最少。
6500K的燈光最白，但藍光最多。
你會揀那一種？

如果用LED的，又好光的，唔好望咁近，唔好玩咁耐。
小心閃吓閃吓的，可能會引發抽筋(腦癇)發作。

在十五的低視能訓練工作中，好像從未想過這種訓練與《奇異恩典》的一句歌詞「瞎眼今得看見」有關。
感謝有人提出，所以寫下此文去解釋兩者的關係。
兩年前文筆稚嫩，現今重新修訂此文：

『瞎眼今得看見』與「低視能訓練」 『瞎眼今得看見』，真的可以嗎？這原來也可以是一種教育、一種工作。 播放 Amazing Grace 時，想起其中一句歌詞『瞎眼今得看見』，突然有所頓悟：過往自己所曾做過的工作，豈不是也致力於使『瞎眼』的學生『看見』嗎？ 除....

在香港，如果想確定兒童是否有CVI，首先是經過醫生，例如腦科，去診斷腦部是否有損傷；而損傷是否影響視覺，則由眼科醫生及視光師作詳細檢查，去判斷兒童的視覺有沒有問題，以及問題在那些方面，例如視力、視野、對焦、斜視、弱視、立體感等等。
至於視障學校的低視能訓練老師，或視障學校為其他特殊學校所提供的資源老師，能替學生評估他/她的功能性視力，即是在視覺運用方面各種能力的情況。
另外，香港的衛生署有兒童體能及智力測驗中心，為學前幼兒作綜合評估，由兒科醫生、視光師及其他治療師等，為幼兒作全面評估，包括是否有腦受損、視覺障礙及CVI，並轉介合適的教育服務。
