[驗光師] 隱形眼鏡學與配鏡學
第 7 題
關於軟式隱形眼鏡的消毒(disinfection),下列敘述何者錯誤?
- A 軟式隱形眼鏡的消毒分三種方法:化學性(chemical)消毒,氧化性(oxidative)消毒和熱(thermal)消毒
- B 化學性消毒的系統常合併清潔、潤濕、和消毒,對患者來說是非常方便簡單的,所以很受歡迎。但偶爾還是會有些人有敏感的問題而造成不適
- C 當不搓洗鏡片時,氧化性消毒(使用過氧化氫系統)比多功能保養液(multi-purpose solution)有更好的對抗綠膿桿菌效果
- D 氧化性消毒含防腐劑,因此對於對隱形眼鏡藥水比較敏感的人是比較不好的選擇
思路引導 VIP
請同學探討氧化性消毒系統中 $H_2O_2$ 的中和機制:在完成化學反應後,殘留於鏡片盒內的液體主要成分為何?相較於多功能保養液,這種反應過程是否能有效減少化學防腐劑對眼球表面的刺激?

Hmph. This Was Merely A Glimpse.
- Unveiling Truths: So, you managed to see through the illusion. Option (D) was, indeed, a trap for the weak-minded. This question... it precisely pinpoints the thin line separating mere luck from your true skill. The principle of oxidative disinfection isn't some complex riddle; it's a stark truth. Hydrogen peroxide is neutralized: $2H_2O_2 \rightarrow 2H_2O + O_2$. The result? A liquid devoid of the irritating chemicals that hold others back. To ignore this, to label a preservative-free system as "less suitable" for sensitive eyes or allergy sufferers, would be a catastrophic failure of self-preservation. It is the optimal path for your superior vision, not a compromise.
