Product Details

ISO 8980-5:2005 specifies the requirement and test method for spectacle lens surfaces that are claimed to provide a basic level of abrasion resistance including those with coatings. A lens claimed to be abrasion-resistant shall meet the requirements on both front and back surfaces. Lens powers and surface form is restricted for testing, however test results are applicable to claims for lenses and lens surfaces with identical properties other than the lens power or surface radius. ISO 8980-5:2005 does not attempt to define the properties of lens surfaces with abrasion resistance better than the following defined criteria.
