Marking on Contact Lenses

Contact lenses were first developed approximately a century ago, with progressive product developments; contact lenses had gradually replaced the traditional spectacles/glasses.

Generally, contact lenses have diameters of 13.5~14mm, and by wearing the lens, human eyes will be able to project a visual angle between diameters of 9~10mm.

Various manufacturers make the most of the blank surface area on lenses to mark their company logo, serial numbers, and other relevant product information. The itched information may include date of manufacture, production batch number, product model and so on. Although the methods adapted for printing are proficient and efficient but generally considered to be less environmentally friendly, therefore using laser marking to replace traditional printing becomes the most ideal solution.

To mark on such a limited surface area of contact lenses requires exceptionally small laser firing spot sizes, and the power output must be maintained at a steady but sufficient level, as too much power may leave markings that are excessive and too deep.
This month the LaserPro Application lab will demonstrate and adapt the LaserPro StellarMark I-series, utilizing its CO2 laser to mark on contact lenses. Please refer to the following sample for an example of 10*10mm lenses, it exhibits meticulous marking results.
 
Tips:
  • Different contact lenses possess different curves; operators should moderately adjust focus accordingly.
  • Before marking begins, please ensure that contact lenses are evenly placed and ready, taking extra caution with focus to ensure best marking results.
