Ophthalmic optics and eye protection tests

There are different types of tests to determine the optical properties of ophthalmic products and personal protective equipment (PPE) used for eye protection. These types of tests are designed to determine whether a product complies with the requirements set by different regulations. Such as sunglasses, reading glasses, PPE, sports glasses, etc.

sunglasses test

Conditions for the marketing and free circulation of personal protective equipment (PPE) within the community are regulated by Directive 89/686/CEE of 21 December. This regulation sets out the basic health and safety requirements that such products need to comply with. These requirements are intended to protect the health of users and keep users safe.

Sunglasses or goggles to protect against solar radiation are classified as Class I personal protective equipment. This classification means that such products do not have to undergo EC type examination, so they are not related to the corresponding certificate.

However, these glasses need to meet the characteristics specified in ISO 12312-1:2015. In addition, the standard specifies the guidelines to be followed when performing tests to evaluate the different optical and mechanical properties of such products.

According to ISO EN UNE 17025:2017, sunglasses can be tested and filter categories determined. Furthermore, in our laboratory we have experience in evaluating different optical properties of such products according to international standards ISO 12311 and ISO 12312, such as UV protection, degree of polarization, photochromism, light diffusion, etc.

Testing services focus on the following points of ISO 12312:

reading glasses test

The population over the age of 45 uses positive energy glasses called presbyopic glasses.

对于这种类型的眼镜的制造，荷兰眼科医生F.C. Donders开发了不同年龄的正常住宿曲线。该曲线是在进行一项研究后获得的，该研究在某些年龄范围与失去聚焦特写物体的能力之间建立了因果关系，这是基于眼睛晶状体随着时间的流逝而失去灵活性。

为了让老花眼患者能够聚焦在附近的物体上，眼科光学行业制造了放大镜。

UNE EN 14139标准将预组装眼镜定义为仅用于近视力和阅读的眼镜。According to该标准，这种类型的眼镜具有或包含一对具有相同正球面功率的单焦点镜片，其中由于合格医生的处方而未进行组装。

这样，按照UNE EN 14139标准给出的预组装眼镜的定义，具有非单焦点镜片（即双焦点，多焦点或渐进镜片）的眼镜不被视为预组装眼镜。

因此，对于消费者来说，需要保证知道预组装眼镜的力量是什么。因此，此类眼镜的制造商和分销商需要对所有批次进行实验室测试。这些测试不仅为客户提供了质量保证，而且还确保了产品标签上标明的效力和特性是其真正具有的。

According toUNE EN 14139标准的指示提供预组装玻璃的测试服务：

蓝光眼镜/蓝光防护测试

近年来，带有蓝光阻挡滤光片的镜片的销售有所增加。这种类型的眼镜，也称为蓝色镜片眼镜，可提供500nm至380nm之间的辐射保护。

然而，尽管这种类型的镜头的销售已经流行起来，但由于制造商和分销商并不总是通过实验室分析来验证蓝光吸收的百分比，因此在许多情况下，产品质量受到影响。

应该注意的是，对于这种类型的镜头，不需要它们吸收一定比例的光，但要求的要求是它们实际吸收的蓝光百分比在产品规格中注明。为此，制造商和分销商应对所有批次进行实验室测试。

个人防护装备测试和眼睛防护

So-called PPE or Personal Protective Equipment for eye protection needs to comply with European standards and therefore needs to bear the "EC" mark prescribed by Royal Decree 1407/1992.

The European standards regulating this equipment are intended to guarantee the performance of the product against harmful optical radiation, shocks, hot solids, drops and splashes of chemical products, etc.

Such products are tested against the harmonized standards that need to be met:

Lens and Frame Testing

In addition to the above tests, we offer different solutions for the testing services and evaluation of the performance of lenses and frames according to the directives of current regulations. These solutions include:
