摘要

目的：了解各種鏡片、隱形眼鏡、及人工水晶體對紫外線的防護效果。
方法：收集各種鏡片、隱形眼鏡、及人工水晶體，以光譜分析儀分析其在紫外線和可見光區的穿透情形，將所得到的各曲線重疊，比較其對紫外線的防護效果。
結果：鏡片方面；經紫外線防護處理的樹脂鏡片對紫外線的防護效果最好，聚碳酸脂鏡片的效果類似，其次為未經處理的樹脂鏡片，玻璃鏡片的效果最差。隱形眼鏡方面：未加紫外線吸收劑的Weicon 38E最差；而在標榜有抗紫外線功效的片子中，Hemaflex、Igel、Ojust三者效果差不多，Weicon Ultrabloc表現最佳；另外也發現隱形眼鏡的基弧與顏色種類均不影響紫外線穿透。人工水晶體方面：Alcon及Pharmacia & Upjohn兩家的人工水晶體，不論是硬式或軟式均能有效地阻擋紫外線。
結論：以鏡片防護紫外線的傷害，本篇建議使用經抗紫外線處理的樹脂鏡片或聚碳酸脂鏡片；隱形眼鏡方面，有添加紫外線吸收劑者較未添加者為佳；抗紫外線的人工水晶體不論是硬式或軟式均有相當於人類水晶體的防護功效，應常規使用於白內障手術。

Purpose: To evaluate the anti-ultraviolet (UV) efficacy of different kinds of spectacle lens, soft contact lens, and intraocular lens.
Methods: The spectral transmissions of spectacle lens, soft contact lens, and intraocular lens are analyzed to compare their anti-UV efficacy.
Results: For spectacle lens: UV CR-39 and polycarbonate lens provide better protection than clear CR-39 lens; glass lens perform worst. For soft contact lens, UV contact lens is better than clear contact lens, and among UV contact lens, Weicon Ultrabloc is the most effective. We also found that the kinds of color and the base curve of the lenses are not related to their anti-UV efficacy. For intraocular lens, both hard and soft lenses from Alcon and Phamacia & Upjohn can block the UV radiation efficiently.
Conclusion: To prevent the damage from UV radiation, we suggest UV CR-39 and polycarbonate lens; as for soft contact lens, the one with UV-absorber is better; both hard and soft UV-intraocular lens perform equally good to human crystalline lens, therefore, they should be used regularly in modern cataract surgery.
