In the development of contact lenses, whether made of glass or plastic, color measurement is used in several contexts<\/p>\n

Clear contact lenses are often very lightly colored so that they are easier to see in the blister. This is where color measurement helps to define the coloration as intensely as necessary, but at the same time as weakly as possible so that it does not affect the visual experience.<\/p>\n

Color measurement can be used to investigate the relationship between the formulation of the lens material and the specific transmission<\/a> of a lens. This allows the desired effects of light<\/a> transmission<\/a> to be specifically generated in the development of new materials or the design of contact lenses.

Regardless of the various optical targets<\/strong>, the spectrophotometer<\/a> is used in quality control to guarantee that the lenses have the same color quality in production, even across different production batches.<\/p>\n

Specially developed holder for measuring contact lenses from HunterLab<\/h3>\n

For the Vista spectrophotometer<\/strong><\/a> spectrophotometer<\/a> from HunterLab, a two-part holder has been specially developed in which contact lenses with a diameter of approx. 13.8 mm or more can be easily inserted in order to measure their transmission<\/a>. To do this, a contact lens is placed over the opening of the holder base and then clamped to the edge with the holder attachment, which adheres magnetically. This fixation prevents wrinkles or deformation of the lens and the entire lens surface can be measured. The entire holder is then inserted into the device in front of the measuring opening. It centers itself – again magnetically – perfectly in front of the ball opening. This system is easy to use and guarantees a highly repeatable measuring method that can be carried out in exactly the same way by all employees.<\/p>\n

Color measurement is essential in the development of contact lenses in order to optimize both coloration and light<\/a> transmission<\/a>. Clear lenses are lightly tinted to facilitate handling without impairing the visual experience. Using specific color measurements, the transmission<\/a> of light<\/a> 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<\/a> colors authentically. HunterLabs Vista spectrophotometer<\/a>, equipped with a specially designed holder, ensures precise and repeatable measurement without deforming the lenses, thus supporting quality control in production. <\/p>\n","protected":false},"author":2,"featured_media":287562,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"on","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[806],"tags":[874,1113],"class_list":["post-291479","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-colorimetry","tag-colour-measurement","tag-contact-lenses"],"_links":{"self":[{"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/posts\/291479","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/comments?post=291479"}],"version-history":[{"count":0,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/posts\/291479\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/media\/287562"}],"wp:attachment":[{"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/media?parent=291479"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/categories?post=291479"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.hunterlab.eu\/en\/wp-json\/wp\/v2\/tags?post=291479"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
