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.

紫外线是我们环境的自然组成部分，zui常见于阳光下。它是电磁辐射的不可见带，正好超出可见光谱的紫罗兰色末端。该频带通常分为短波长，中波长和长波长区域，它们对人体的影响不同。
短波长区域也称为远紫外线，shajun或UV-C，范围从180到280nm。尽管它的穿透力很小，但短波会严重灼伤眼睛和皮肤。这种辐射的通常的人工来源是低压，汞蒸气灯和某些其他金属蒸气灯，用于紫外线shajun，色谱法，矿物学，EPROM擦除，光化学反应等。
中等波长区域也称为中紫外线，红热或UV-B，范围从280到320nm。它具有很高的穿透力，可以严重灼伤眼睛和皮肤。这种辐射的通常的人工来源是用于美容或治疗目的以及产生维生素的“日光灯”。
长波长区域（也称为近紫外光，黑光，伍德光或UV-A）的范围从320到400nm。有些人对该区域的辐射过于敏感，在查看长波紫外线源时可能会遇到“蓝雾”干扰。
尽管每个人每天都暴露于天然和/或人工的紫外线源中，但未经保护并长时间暴露于任何形式的紫外线（包括长波紫外线）下，都可能导致白内障，甚至可能导致癌症。如果强度足够高，则即使是短暂的暴露也可能是危险的。
专为长期佩戴而设计，并保护用户免受大多数紫外线光源的伤害
通过消除“蓝雾”干扰来改善荧光区域和背景之间的对比度
通常建议将UVS-30眼镜用于零星，低强度的紫外线源，从而可以轻松地戴在眼镜上
UVF-80面罩，可针对长时间或高强度紫外线暴露提供zui大程度的保护，可根据面部情况进行调整
护目镜和面罩符合ANSI规范和OSHA标准

UVF-80防紫外线面罩
UVF-80防紫外线面罩中的吸收紫外线的材料符合有关安全眼镜的ANSI规范Z87.1和有关眼睛和面部防护的OSHA标准1910.133。 虽然面罩可为裸露的皮肤提供大量保护，但它们被认为是次要的眼部保护，尤其是在短波或中波紫外线下长时间工作或可能出现“杂散”紫外线的情况下。 因此，建议将面罩与主眼保护器配合使用。 Spectro-UV提供完整的主紫外线防护和荧光增强眼镜系列。

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.
