Colour measurement of contact lenses and spectacle lenses

Contact lenses and glasses are not only used to correct eye conditions such as short-sightedness, long-sightedness, astigmatism and presbyopia, but are also a fashion accessory and part of a person’s personal image.

Plastic lenses are currently the most commonly used lenses, as they are relatively safe, inexpensive and easy to manufacture, as well as having outstanding optical quality.

HunterLab supports quality assurance throughout the entire manufacturing process: starting with the blanks, incoming QA tests of the liquid polymer components through to the end product lens or glass (but also spectacle frames and contact lens blister packaging). This also includes the film that serves as a polarizer for sunglasses and as an anti-reflective coating.

HunterLab spectrophotometers detect deviations and reduce the error rate of glasses and lenses, which are usually made of plastic. They determine optical clarity, enable colour tests with regard to tinting properties, as well as weathering and performance tests.
