1.2.2.2 Oculars with filtering action (filters) and housings for oculars with filtering action.

The transmittance of oculars with filtering action shall meet the requirements given in the specific standards relating to the various types of oculars (see 7.2.1). Goggles and face-shields which claim to provide protection against optical radiation shall provide at least the same

level of protection against optical radiation as given by a filter of any scale number declared usable with the eye- protector by the manufacturer or supplier. Testing shall be in accordance with clause 6 of EN 167:2001. 具有过滤作用的眼镜（过滤器）和具有过滤作用的眼镜外壳。

具有过滤作用的目镜的透射率应符合与各种类型目镜相关的特定标准中给出的要求（见7.2.1）。声称能提供光学辐射防护的护目镜和面罩应至少提供相同的防护

制造商或供应商声明可与护目镜一起使用的任何刻度数的滤光片所提供的光辐射防护等级。测试应符合EN 167:2001第6条的规定。

1.2.2.3.1 Oculars without corrective effect Variations in luminous transmittance shall be measured in accordance with clause 7 of EN 167:2001. The relative variations of the luminous transmittance around the visual center(s) P1 (and P2) shall not exceed the values of Table 4. The relative difference in luminous transmittance P3 between left and right eye shall not exceed the values of Table 4 or 20 % whichever is greater.应根据EN 167:2001第7条的规定测量光透射率无校正效果变化的眼睛。视觉中心P1（和P2）周围透光率的相对变化不得超过表4的值。左眼和右眼之间透光率P3的相对差异不得超过表4中的值或20%，以较大者为准。

1.2.2.3.2 Oculars with corrective effect (prescription oculars) 具有矫正效果的眼科医生（处方眼科医生）

The requirements of 7.1 .2.2.3.1 shall also apply to prescription oculars, with the provision that variations in luminous transmittance which are due to thickness variations inherent in the design of the ocular are not taken into account, providing the luminous transmittance at no point deviates by more than a factor of 2,68 (one shade number) from its value at the visual center. The IR and UV transmittance shall meet the requirements of the specified shade number at every point on the ocular. 7.1的要求。2.2.3.1还应适用于处方眼镜，但前提是不考虑因眼镜设计固有厚度变化引起的透光率变化，前提是任何点的透光率与其视觉中心值的偏差均不超过2.68倍（一个阴影数）。红外和紫外线透射率应满足目镜上每个点的规定阴影数要求。

1.2.3 Diffusion of light光的扩散

The diffusion of light shall be measured in accordance with one of the reference methods specified in clause 4 of EN 167:2001.

The maximum value of the reduced luminance factor shall be:

应按照EN 167:2001第4条规定的参考方法之一测量光的扩散。

降低亮度因数的Zui大值应为：

1.3 Quality of material and surface材料和表面质量

Except for a marginal area 5 mm wide, oculars shall be free from any significant defects likely to impair vision in use, such as bubbles, scratches, inclusions, dull spots, pitting, mould marks, scouring, grains, pocking, scaling and undulation. The assessment shall be carried out in accordance with the method specified in clause 5 of EN 167:2001. 除5 mm宽的边缘区域外，目镜应无任何可能影响使用中视力的重大缺陷，如气泡、划痕、夹杂物、暗斑、点蚀、霉菌痕迹、冲刷、颗粒、麻点、剥落和起伏。应按照EN 167:2001第5条规定的方法进行评估。

1.4 Robustness稳健性

7.1.4.1 Minimum robustnessZui小鲁棒性

This requirement relates only to cover plates and oculars with filtering effect and need not be assessed if these items are intended to meet the requirements for increased robustness or resistance to high-speed particles, in which case the requirements of 7.1 .4.2 or 7.2.2 shall be met. The requirement for minimum robustness is satisfied if the ocular withstands the application of a 22 mm nominal diameter steel ball with a force of (1 00 ± 2) N, when tested in accordance with clause 4 of EN 168:2001. On so testing the following defects shall not occur:

a) ocular fracture: an ocular shall be considered to have fractured if it cracks through its entire thickness into two or more pieces, or if more than 5 mg of the ocular material becomes detached from the surface away from the one in contact with the ball, or if the ball passes through the ocular;

b) ocular deformation: an ocular shall be considered to have been deformed if a mark appears on the white paper on the opposite side to the one on which the force is applied.

本要求仅适用于具有过滤效果的盖板和目镜，如果这些项目旨在满足增强鲁棒性或抗高速粒子的要求，则无需对其进行评估，在这种情况下，应符合7.1的要求。应满足4.2或7.2.2的要求。当根据EN 168:2001第4条进行试验时，如果目镜能够承受标称直径为22 mm的钢球施加的力为（100±2）N，则满足Zui小稳健性要求。进行so测试时，不得出现以下缺陷：

a） 眼球骨折：如果眼球整个厚度裂成两片或多片，或者如果超过5 mg的眼球材料从与球接触的表面分离，或者如果球穿过眼球，则视为眼球骨折；

b） 眼部变形：如果在白纸上施加力的另一侧出现标记，则视为眼部变形。

1.4.2 Increased robustness增强的鲁棒性

1.4.2.1 Unmounted oculars未安装的目镜

The oculars shall withstand the impact of a 22 mm nominal diameter steel ball, of 43 g minimum mass, striking the ocular at a speed of approximately 5,1 m/s, when tested in accordance with 3.1 of EN 1 68:2001. On so testing the following defects shall not occur:

a) ocular fracture: an ocular shall be considered to have fractured if it cracks through its entire thickness into two or more pieces, or if more than 5 mg of the ocular material becomes detached from the surface away from the one struck by the ball, or if the ball passes through the ocular;

b) ocular deformation: an ocular shall be considered to have been deformed if a mark appears on the white paper on the opposite side to that struck by the ball.

当按照EN 168:2001的3.1进行试验时，目镜应能承受Zui小质量为43 g、标称直径为22 mm的钢球以大约5.1 m/s的速度撞击目镜的冲击。进行so测试时，不得出现以下缺陷：

a） 眼球骨折：如果眼球在整个厚度上裂成两片或多片，或者如果超过5 mg的眼球材料从远离被球击中的表面脱离，或者如果球穿过眼球，则视为眼球骨折；

b） 眼部变形：如果白纸上出现与球击相对的标记，则视为眼部变形。

1.4.2.2 Complete eye-protectors and frames完整的护目镜和框架
The complete eye-protector or frame shall withstand the lateral and frontal impacts of a steel ball striking at a specified speed. The diameter of the steel ball and the corresponding impact speed are given in Table 5. The test shall be in accordance with the method specified in 3.2 of EN 1 68:2001. If a spectacle is claimed to have lateral protection it shall not be possible for the ball to strike the lateral impact points without first striking the lateral protection. On so testing the following defects shall not occur:
a) ocular fracture: an ocular shall be considered to have fractured if it cracks through its entire thickness into two or more pieces, or if more than 5 mg of the ocular material becomes detached from the surface away from the one struck by the ball, or if the ball passes through the ocular;
b) ocular deformation: an ocular shall be considered to have been deformed if a mark appears on the white paper on the opposite side to that struck by the ball;
c) ocular housing or frame fracture: an ocular housing or frame shall be considered to have failed if it separates into two or more pieces, or if it is no longer capable of holding an ocular in position, or if an unbroken ocular detaches from the frame, or if the ball passes through the housing or frame;
d) lateral protection failure: the lateral protection shall be considered to have failed if it fractures through its entire thickness into two or more separate pieces, or if one or more particles become detached from the surface remote from the impact point, or if it allows the ball to penetrate completely, or if it partially or totally detaches from the eye-protector, or if its component parts become separated.
