About The Position

The Lens Drill Mounting Technician is a specialized mounting role responsible for assembling rimless (drill-mount and three-piece) eyewear, where prescription lenses attach directly to the bridge and temples through precisely drilled holes rather than a frame rim. This position requires advanced precision, controlled drilling technique, and strong knowledge of lens materials, as errors can crack or chip finished lenses. The technician delivers high-quality rimless eyewear that meets both functional and aesthetic standards while minimizing scrap and rework.

Responsibilities

Lens Layout & Drilling: Mark and drill mounting holes into finished lenses at the correct position, angle, and depth to match the frame hardware. Use manual drill mounts and/or CNC drilling equipment to produce clean, properly aligned holes that allow the lens to seat square without stress.
Lens Material Selection & Handling: Identify lens material before drilling and adjust technique accordingly, recognizing that polycarbonate and Trivex tolerate drilling well while glass, CR-39, and certain high-index materials are more prone to cracking. Manage stress points around drilled holes to protect lens integrity and reduce breakage and scrap.
Rimless Assembly & Fit: Attach lenses directly to the bridge and temples using screws, bushings, or compression fittings, ensuring a secure, stress-free hold. Align frame components so the finished pair sits straight and balanced, and confirm correct axis positioning for multifocal and progressive lenses.
Quality Control & Cosmetic Inspection: Inspect drilled lenses and assembled rimless eyewear for cracks, chips, stress marks, or cosmetic defects around hole sites and mounting points. Verify that all components meet internal quality benchmarks and industry standards before the job advances.
Secure Assembly: Tighten and secure all screws, bushings, and fittings so lenses are firmly held with no rotation or play at the mounting points. Maintain the structural integrity and long-term durability of the finished rimless product.
Lens Mounting & Frame Fitting: Accurately mount prescription lenses into designated frame sides (right/left), ensuring proper sizing, fit, and orientation. Utilize specialized beveling techniques tailored to individual prescriptions to achieve optimal lens placement.
Frame Alignment & Adjustment: Perform manual adjustments using hand tools to align frames according to optical standards. Ensure four-point contact, square temple alignment, minimal front wrap, and symmetrical pad arms. Correct any bridge twist and verify even temple closure for a balanced fit.
Optical Verification: Confirm the correct axis positioning for multifocal lenses, including bifocals and progressives. Ensure horizontal alignment and visual accuracy to support optimal wearer experience.
Quality Control & Cosmetic Inspection: Conduct thorough inspections of lenses and frames to identify and correct cosmetic defects, scratches, or imperfections. Verify that all components meet internal quality benchmarks and industry standards.
Secure Assembly: Tighten and secure all screws, ensuring there are no gaps in the eye wire and that lenses are firmly seated within the frame. Maintain structural integrity and durability of the final product.
Compliance & Standards: Adhere to company protocols and regulatory guidelines for lens mounting and frame assembly. Maintain a clean and organized work environment to support consistent quality output.
