Color 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 color tests with regard to tinting properties, as well as weathering and performance tests.

Color measurement of contact lenses

Color measurement of contact lenses

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light transmission. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission of light through the lenses can be precisely analyzed and controlled depending on the material. For tinted lenses, the precise measurement makes it possible to change eye colors authentically. HunterLabs Vista spectrophotom...
