我17歲 看遠驗到75遠視25散光 看近則有200遠視25散光 其實成因是甚麼？17歲老花？看遠只有75度遠視需要配戴眼鏡嗎？

遠視並不等於老花。

  • 遠視是眼睛所見到的影像對焦在眼視網膜的後面，多是由於眼球過細(視軸過短)引起。零至6歲的兒童通常都會有輕微遠視，這類遠視一般會隨眼球成長而自然矯正。但患深遠視的兒童(超過300度)由於經常要大幅度調節焦點看近距離的事物，如看書或電腦，容易感到眼睛疲勞而對焦不清。遠視可按個別需要，透過配戴凸透鏡，矯正視力。
  • 老花是由於眼球內的捷狀肌及晶狀體隨年紀老化、變硬，失去原有的彈性及調節力，以致在看近物如看書、看報紙時，對焦會感到吃力或模糊。老花大多於40歲時開始出現，至60歲後度數便會逐漸穩定下來。老花可透過單光鏡片、雙光鏡片或漸進鏡片來改善視力。

200度的遠視度數，有機會看近比較吃力，如有需要，可考慮驗配合適的眼鏡幫助視物。

《Classroom – 醫療保健》我的小朋友分別到顏色嗎？

(Chinese Version Only)

一般家長難以察覺孩子是否有顏色問題，眼科視光師一般最常用的是石原氏色板檢查 (Ishihara test)，顏色卡上的數目字並非每個人都可看得見。我們能夠分辨顏色， 是因為眼睛的視網膜有三種顏色感光細胞，分別為紅色、綠色和藍色。視覺神經把信息傳送到大腦分析，經過這三個細胞混合，便可看見白光。如果視網膜細胞有缺損，或信息傳送系統出現問題，便會影響分辨顏色的能力。很多人經常混淆色盲和色弱。色盲較為罕有，患者只能看見黑白深淺之分。色弱是常見的視覺問題，男性患病百分比約8%，女性約0.5%。色弱是指患者不能辨別某些顔色，當中紅色弱、綠色弱最為普遍。色弱多屬遺傳，影響雙眼。如果由受傷或疾病引起的，一般只會影響單眼。

色弱暫時並沒有治療方法，色弱學童在學習上可能要靠光度強弱來分辨顏色，某程度上會對生活帶來一些不便或障礙。視乎色弱程度，可以考慮佩戴濾鏡幫助小朋友增加對顏色的敏感度，不過要完全根治就暫時並沒有方法。小朋友將來在學科及職業選擇方面可能會受到影響，例如不能從事對顏色精準度高的工作，如民航機師、藥劑師及紀律部隊等。家長如有疑問，應找眼科視光師進行全面眼科視光檢查。
