Method for handling a lens

A method for wet-coating an eyeglass lens with a processing system including a fluid container for holding the fluid for wet-coating the eyeglass lens and a packaging system which defines a rotational axis and includes a carrier device and the eyeglass lens accommodated thereon, the eyeglass lens having first and second lens surfaces and a lateral peripheral edge delimiting said first and second lens surfaces and defining an edge surface extending between said first and second lens surfaces;

• the carrier device including:
• a main body;
• a singular annular connecting member directly contact engaging both said main body and said lens and being configured to releasably connect said main body to said lens;
• said lens being accommodated in said carrier device so as to cause said first lens surface to face toward said main body and said second lens surface to face away from said main body;
• said main body and said connecting member conjointly defining a protective cover surrounding said first lens surface thereof facing toward said main body;
• said connecting member being in contact engagement with said edge surface when said lens is held in said carrier device;
• said connecting member being one of:
• an adhesive tape placed around the lateral edge of the lens and a clamping ring engaging around the lateral edge of the lens;
• and,
• said fluid container including a conduit having several nozzles for directing said fluid to said second lens surface;
• the method comprising the following steps:
• lowering said packaging system into said fluid container above said nozzles of said conduit and the surface of said fluid;
• and,
• moving fluid from said fluid container into said conduit and through said nozzles toward said second surface of said eyeglass lens while simultaneously rotating said packaging system about said rotational axis to drive said coating fluid under the effect of centrifugal force to the edge of the eyeglass lens thereby ensuring that the layer of fluid applied to the eyeglass lens adheres to said second surface with a uniform layer thickness.

A method for coating an eyeglass lens with a processing system including a vapor deposition system for vapor depositing a coating on the eyeglass lens and a packaging system which includes a carrier device and the eyeglass lens accommodated thereon, the eyeglass lens having first and second lens surfaces and a lateral peripheral edge delimiting said first and second lens surfaces and defining an edge surface extending between said first and second lens surfaces and each of said first and second lens surfaces defining a surface centroid;

• the carrier device including:
• a main body;
• a singular annular connecting member directly contact engaging both said main body and said lens and being configured to releasably connect said main body to said lens;
• said lens being accommodated in said carrier device so as to cause said first lens surface to face toward said main body and said second lens surface to face away from said main body;
• said main body and said connecting member conjointly defining a protective cover surrounding said first lens surface thereof facing toward said main body;
• said connecting member being in contact engagement with said edge surface when said lens is held in said carrier device;
• said connecting member being one of:
• an adhesive tape placed around the lateral edge of the lens and a clamping ring engaging around the lateral edge of the lens;
• and,
• said vapor deposition system including a calotte having an inner surface and a vapor deposition device for directing vaporized coating material to said second lens surface;
• the method comprising the following steps:
• attaching a plurality of said packaging systems to said inner surface of said calotte so as to cause the second lens surface to face toward said vapor deposition device;
• adjusting said packing systems so as to cause the centroid of corresponding ones of said second lens surfaces to lie in an imaginary spherical surface concentric with said inner surface of said calotte;
• and,
• simultaneously vapor depositing said coating material onto said second lens surfaces of corresponding ones of said eyeglass lenses.

• the carrier device including:
• a main body;
• a singular annular connecting member directly contact engaging both said main body and said lens and being configured to releasably connect said main body to said lens;
• said lens having a vertex and being accommodated in said carrier device so as to cause said first lens surface to face toward said main body and said second lens surface to face away from said main body;
• said main body and said connecting member conjointly defining a protective cover surrounding said first lens surface thereof facing toward said main body;
• said connecting member being in contact engagement with said edge surface when said lens is held in said carrier device;
• said connecting member being one of:
• an adhesive tape placed around the lateral edge of the lens and a clamping ring engaging around the lateral edge of the lens;
• and,
• said processing system including a container defining a vertical axis and being configured for receiving and holding the fluid for wet-coating the second lens surface of said eyeglass lens and a circulating arrangement for circulating the fluid through said container;
• the method comprising the following steps:
• circulating the fluid through said container;
• immersing said carrier device with said eyeglass lens obliquely into said fluid so as to cause said rotational axis and said vertical axis to conjointly define an angle β and so as to cause the eyeglass lens to be immersed up to said vertex thereof;
• and,
• rotating said carrier device with said eyeglass lens about said rotational axis so as to drive said fluid under the effect of centrifugal force to the edge of the eyeglass lens.
