What is protective eyewear?

Protective eyewear is designed to protect the area surrounding the eye to reduce risk of injury. It is made of special pieces of strong glass or plastic in a frame that fits tightly to wearer’s face. Examples of risks requiring eye protection can include impact from particles, light or radiation, wind blast, heat, etc. Protective eyewear can be categorized into several types based on the style of eye wear and the targeted hazard, such as face shields and safety goggles.

Face shields and safety goggles that are intended for use as personal protective equipment (PPE) must comply with different standards depending on the market in which they are sold.

Protective Eyewear Compliance Requirements

UK/ EU

In the UK/ EU, protective eyewear are regulated under the PPE Regulation. Usually, protective eyewear are classified as Category 2 PPE, which means that EU Type examination is required by a Notified Body in EU (or Type examination to be carried out by the Approved Body in UK).

The test standard that applies to these products in UK/ EU is EN 166. Testing to this standard is the first step in the conformity assessment process.

Below is a summary of the key requirements of EN 166:

EN 166 : 2002Test descriptionDescription or requirements
Clause 6.1General constructionShall be free from projections, sharp edges or other defects which are likely to cause discomfort or injury during use
Clause 7.1.2.1Refractive powersThe spherical, astigmatic and prismatic refractive powers shall be within the permissible tolerances according to the relevant optical class 1, 2 or 3
Clause 7.1.2.2TransmittanceLuminous transmittance (380 – 780 nm) shall be greater than 74.4%
Clause 7.1.4.2Increased robustnessThe lenses shall withstand the impact of a ⌀22mm steel ball, of 43 g mass, striking the lenses at a speed of approx. 5.1 m/s without lenses fracture or deformation. The housing or frame cannot separate into 2 or more pieces and shall hold the lenses in position

Once testing to EN 166 has been completed, the conformity assessment body (EU Notified Body or UK Approved Body) can review the test data together with other technical documentation about the product. When the conformity certificate is issued, the importer or distributor may affix the CE Mark for EU (or UKCA Mark for UK) to the product in accordance with the requirements of the PPE Regulation.

USA

In the US, the standard is ANSI/ISEA Z87.1. The tests covered in the ANSI standard are similar to those in the EN standard, but with some differences.

Below is a summary of key requirements of ANSI/ISEA Z87.1 standard:

ANSI/ISEA Z87.1 : 2020Test descriptionRequirement
Section 5.1.1Optical qualityLenses shall be free of striae, bubbles, waves and other visible defects which would impair the wearer’s vision.
Section 5.1.3HazeClear plano lenses shall not exhibit more than 3% haze when measured by the apparatus and procedure as described in ASTM D1003.
Section 5.2.1Drop Ball Impact resistanceThe lens shall remain intact with the frame and shall not fracture or have any fragment detached from the surface, or allow the projectile penetrates the inner surface after a ⌀1.0 in steel ball, weighing 68g (2.4 oz) freely dropped from a height of 127cm (50 in.) onto the lens.
Section 5.2.2IgnitionNo ignition or glowing upon the removal of a hot rod (650 °C) in contact with any component of the device for 5 sec.
