Spectacles Testing and Standards

The range of eyewear products is very broad and includes everything from everyday eyewear to speciality goggles.

They range from everyday eyewear to speciality goggles. Different quality standards may apply to different eyewear products in terms of type and specific use, but durability and product safety remain important considerations for such products.

However, durability and product safety remain important considerations for such products.
