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.

紫外線是我們環境的自然組成部分，zui常見于陽光下。它是電磁輻射的不可見帶，正好超出可見光譜的紫羅蘭色末端。該頻帶通常分為短波長，中波長和長波長區域，它們對人體的影響不同。
短波長區域也稱為遠紫外線，shajun或UV-C，范圍從180到280nm。盡管它的穿透力很小，但短波會嚴重灼傷眼睛和皮膚。這種輻射的通常的人工來源是低壓，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，EPROM擦除，光化學反應等。
中等波長區域也稱為中紫外線，紅熱或UV-B，范圍從280到320nm。它具有很高的穿透力，可以嚴重灼傷眼睛和皮膚。這種輻射的通常的人工來源是用于美容或治療目的以及產生維生素的“日光燈”。
長波長區域（也稱為近紫外光，黑光，伍德光或UV-A）的范圍從320到400nm。有些人對該區域的輻射過于敏感，在查看長波紫外線源時可能會遇到“藍霧”干擾。
盡管每個人每天都暴露于天然和/或人工的紫外線源中，但未經保護并長時間暴露于任何形式的紫外線（包括長波紫外線）下，都可能導致白內障，甚至可能導致癌癥。如果強度足夠高，則即使是短暫的暴露也可能是危險的。
專為長期佩戴而設計，并保護用戶免受大多數紫外線光源的傷害

通常建議將UVS-30眼鏡用于零星，低強度的紫外線源，從而可以輕松地戴在眼鏡上
UVF-80面罩，可針對長時間或高強度紫外線暴露提供zui大程度的保護，可根據面部情況進行調整
護目鏡和面罩符合ANSI規范和OSHA標準

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安全眼鏡的ANSI規范Z87.1和有關眼睛和面部防護的OSHA標準1910.133。 雖然面罩可為裸露的皮膚提供大量保護，但它們被認為是次要的眼部保護，尤其是在短波或中波紫外線下長時間工作或可能出現“雜散”紫外線的情況下。 因此，建議將面罩與主眼保護器配合使用。 Spectro-UV提供完整的主紫外線防護和熒光增強眼鏡系列。

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.
