Our machine vision solutions deliver increased yields in smart lens production processes. Maximize quality and eliminate costly escapes, coupled with real-time data and alerts.
Leverage traditional and artificial intelligence (ai) vision inspection to automatically find lens defects and anomalies as they happen, during the manufacturing cycle. Abnormalities in the manufacture of contact lenses are uncovered immediately.
100% automatically inspected and validated contact lenses are shipped out the door with meaningful data. Equip your production supervisors with real-time data at their fingertips, recognising yield drift, quarantining suspect lenses, and keeping your management in the loop with real statistics. Meticulous inspection processes for contact lens production throughout the entire factory floor.
High-speed inspection of contact lenses covers all the areas of quality control. All defect categories are analysed at speed, and individual contact lenses are segregated for failure type, deviation and failure data. Reject cosmetic, mould flaws, inclusions and surface failures on contact lenses. Check monomer defects. Confirm the cavity ID on moulds. Inspect blister packs for lens presence. Confirm lot and date codes cross-match and are printed correctly. Complete vision inspection solutions across contact lens production.
Integrate with existing parametric tests, measurement systems, and custom data sources from your lens production. Optimise line efficiency, and increase yield, while guaranteeing contact lens production quality. IVS systems are designed to integrate directly with all modern MES, SQL and process control platforms.
Reduce the time and effort spent manually inspecting contact lenses by automating traditional quality control processes.
Automate radius of curvature inspection of moulds for sphere and toric with no requirement for focus/set-up prior to inspection. Latest generation interferometer with high precision Z-axis with submicron position accuracy – fully automated.
Check lens thickness with state-of-the-art automated line confocal. Metrology-grade performance with a high dimensional accuracy of multi-layered transparent materials.

The nature of the production process of contact lenses means that it is imperative that the contact lens is inspected as part of the manufacturing quality. Injection moulding is commonly used in the production of soft contact lenses. To shape the lenses, the material is heated to its melting point and then injected into a mould. When the substance hardens, it adopts the form of a contact lens. The cleaning of this lens requires the removal of some unnecessary material, and ultimately the final lens will need to be inspected for shape, inclusions, mould defects and surface inspection.
Hydrogel is the material of choice for most soft lenses. Because of its high water content, this polymer improves oxygen delivery to the eye. A very high percentage of water can be found in some types of soft contact lenses. However, some individuals find it bothersome as adding more water also makes the lens bigger. Because of the reduction in water, the lens can be made thinner and more comfortable.
Silicone hydrogel soft lenses are more recent. With these modern materials, oxygen transmission can be improved without increasing lens size. Compared to rigid gas-permeable lenses, soft contact lenses are more pleasant for the wearer and require less adjustment time.
