Techniques and devices are disclosed for a fabrication layout device and assembly table. The device includes a table with a work surface. The work surface being a continuous surface and configured to support a plurality of railing pieces for fabrication of a railing assembly. The device further includes a beam located above the work surface. The beam is operatively coupled to the table, such that the beam moves relative to the work surface in a first direction. Attached to the beam is an ink dispenser. The ink dispenser is configured to move along the beam in a second direction different from the first direction. The ink dispenser is further configured to dispense ink onto the work surface of the table in the form of a pattern of the railing assembly. Railing pieces can be positioned on the pattern so that they can be assembled to one another.

Hydrophilic contact lenses comprised of a copolymer of an hydroxyl group-containing monomer and N-vinylpyrrolidone are tinted by impregnating the lens with an aqueous solution of a dichlorotriazine reactive dye and fixing the dye in the lens by contacting the lens with an aqueous alkaline solution.

Cellulose esters are cured by exposure to radiation preferably followed by exposure to elevated temperatures of at least about 100.degree. C. In addition, polymers obtained from reacting certain cellulose esters with certain polymerizable silicon esters are provided. The cured cellulose esters are suitable for producing transparent parts such as contact lenses.
