紫外线对眼的影响—电光性眼炎,雪眼等。焊接电弧光产生紫外线波长的分布,由于焊接种类不同分为320～400nm的近紫外光谱,220～315nm的中紫外光谱。眼角膜能吸收320nm以下的短波长的大部分,如暴露量多270nm以下的光谱则发生角膜炎。多种学说认为影响最强的波长是270nm或288nm,在此波长区域的紫外线放射量多时,即使暴露一瞬间也会受到损害,波及到深部。
The impact of UV on the eye - electro-optic ophthalmia, snow eyes and so on. Welding arc light generated UV wavelength distribution, due to the different types of welding is divided into 320 ~ 400nm near-UV spectrum, 220 ~ 315nm UV spectrum. Corneas can absorb most of the short wavelengths below 320 nm, and keratitis occurs when the exposure is below 270 nm. A variety of doctrines that the most influential wavelength is 270nm or 288nm, in this wavelength region of ultraviolet radiation for a long time, even if exposed for a moment will be harmed, spread to the deep.
