Ultraviolet light is a natural part of our environment, most commonly found in sunlight. It is an invisible band of electromagnetic radiation just beyond the violet end of the visible spectrum. This band is generally divided into short,medium and long wavelength regions that differ in their effects on the human body.
The short wavelength region, also known as far ultraviolet, germicidal or UV-C, extends from 180 to 280nm. Although it has little penetrating power, short wave can cause severe burns to the eyes and skin. The usual artificial sources of this radiation are low pressure, mercury vapor lamps and certain other metal vapor lamps used in UV sterilization, chromatography, mineralogy, EPROM erasing, photochemical reaction, etc.
The medium wavelength region, also known as middle ultraviolet, erythermal or UV-B, extends from 280 to 320nm. It has high penetrating power and can seriously burn the eyes and skin. The usual artificial sources of this radiation are “sun lamps” used for cosmetic or therapeutic purposes and vitamin production.
The long wavelength region, also known as near ultraviolet, black light, Wood’s light or UV-A, extends from 320 to 400nm. Some people are overly sensitive to radiation in this region and may experience “blue haze” interference when viewing sources of long wave UV.
Although everyone is exposed to UV sources natural and/or artificial on a daily basis, unprotected and prolonged exposure to any form of UV light, including long wave UV, can result in cataracts and possibly cancer. Even brief exposures can be hazardous if the intensity is high enough.

紫外線是我們環(huán)境的自然組成部分，zui常見(jiàn)于陽(yáng)光下。它是電磁輻射的不可見(jiàn)帶，正好超出可見(jiàn)光譜的紫羅蘭色末端。該頻帶通常分為短波長(zhǎng)，中波長(zhǎng)和長(zhǎng)波長(zhǎng)區(qū)域，它們對(duì)人體的影響不同。
短波長(zhǎng)區(qū)域也稱(chēng)為遠(yuǎn)紫外線，shajun或UV-C，范圍從180到280nm。盡管它的穿透力很小，但短波會(huì)嚴(yán)重灼傷眼睛和皮膚。這種輻射的通常的人工來(lái)源是低壓，汞蒸氣燈和某些其他金屬蒸氣燈，用于紫外線shajun，色譜法，礦物學(xué)，EPROM擦除，光化學(xué)反應(yīng)等。
中等波長(zhǎng)區(qū)域也稱(chēng)為中紫外線，紅熱或UV-B，范圍從280到320nm。它具有很高的穿透力，可以嚴(yán)重灼傷眼睛和皮膚。這種輻射的通常的人工來(lái)源是用于美容或治療目的以及產(chǎn)生維生素的“日光燈”。
長(zhǎng)波長(zhǎng)區(qū)域（也稱(chēng)為近紫外光，黑光，伍德光或UV-A）的范圍從320到400nm。有些人對(duì)該區(qū)域的輻射過(guò)于敏感，在查看長(zhǎng)波紫外線源時(shí)可能會(huì)遇到“藍(lán)霧”干擾。
盡管每個(gè)人每天都暴露于天然和/或人工的紫外線源中，但未經(jīng)保護(hù)并長(zhǎng)時(shí)間暴露于任何形式的紫外線（包括長(zhǎng)波紫外線）下，都可能導(dǎo)致白內(nèi)障，甚至可能導(dǎo)致癌癥。如果強(qiáng)度足夠高，則即使是短暫的暴露也可能是危險(xiǎn)的。
專(zhuān)為長(zhǎng)期佩戴而設(shè)計(jì)，并保護(hù)用戶免受大多數(shù)紫外線光源的傷害
通過(guò)消除“藍(lán)霧”干擾來(lái)改善熒光區(qū)域和背景之間的對(duì)比度
通常建議將UVS-30眼鏡用于零星，低強(qiáng)度的紫外線源，從而可以輕松地戴在眼鏡上
UVF-80面罩，可針對(duì)長(zhǎng)時(shí)間或高強(qiáng)度紫外線暴露提供zui大程度的保護(hù)，可根據(jù)面部情況進(jìn)行調(diào)整

UVF-80防紫外線面罩
UVF-80防紫外線面罩中的吸收紫外線的材料符合有關(guān)安全眼鏡的ANSI規(guī)范Z87.1和有關(guān)眼睛和面部防護(hù)的OSHA標(biāo)準(zhǔn)1910.133。 雖然面罩可為裸露的皮膚提供大量保護(hù)，但它們被認(rèn)為是次要的眼部保護(hù)，尤其是在短波或中波紫外線下長(zhǎng)時(shí)間工作或可能出現(xiàn)“雜散”紫外線的情況下。 因此，建議將面罩與主眼保護(hù)器配合使用。 Spectro-UV提供完整的主紫外線防護(hù)和熒光增強(qiáng)眼鏡系列。

UVS-30 UVG-50 UV Protective Eyewear
The UV-absorbing material in the UVF-80 face shield meets ANSI specification Z87.1 for safety eyewear and OSHA standard 1910.133 for eye and face protection. While face shields offer a good deal of protection for exposed skin, they are considered to be secondary eye protection, especially when working for extended periods with short or medium wave UV or when “stray” UV exposure is possible. Therefore, it is recommended that all face shields be used in conjunction with a primary eye protector. Spectro-UV offers a complete line of primary UV protective and fluorescence-enhancing eyewear.
