When someone orders glasses online or in a store, the frame and lenses do not magically appear together. Somewhere in a lab, a technician picks the right lens blanks, an edging machine cuts them to the exact shape of the frame, a fitter mounts them, a quality checker verifies the power and alignment, and a packer seals the box for dispatch. Large eyewear companies like Lenskart run this work at scale in manufacturing and fulfilment facilities – the company has a large facility in Bhiwadi, Rajasthan, among others – and these operations hire 10th pass, 12th pass and ITI candidates for hands-on technical and warehouse work.
This guide explains the behind-the-scenes jobs in an eyewear lab and warehouse: what each role does, the skills involved, approximate pay, how to apply and what working conditions are like. Brand information is on the official Lenskart website.
How an Eyewear Order Flows Through the Lab
- Order received – prescription, lens type, coating and frame details arrive from a store or online.
- Lens picking – the correct lens blanks are picked from stock (or surfaced for complex prescriptions).
- Coating – some lenses pass through coating processes such as anti-reflection.
- Tracing and edging – the frame shape is traced and the edging machine cuts each lens to fit, with the optical centre in the right place.
- Fitting – lenses are mounted in the frame; screws and nylon threads are adjusted.
- Quality check – power, axis, centration, scratches and frame alignment are verified.
- Packing and dispatch – glasses are cleaned, packed with case and cloth, labelled and sent to the store or customer.

Skills You Will Learn
- Reading prescriptions: SPH, CYL, AXIS, ADD, PD and fitting height.
- Using lensometers and edging machine software.
- Handling lenses without scratches; cleanroom-like discipline in coating areas.
- Frame adjustment techniques for metal, acetate and rimless designs.
- Scanner-based picking, packing standards and dispatch documentation.
These skills are useful at any optical lab, eyewear chain or independent optician – a real trade you can build on.
A Day in the Lab
Shifts start with a quick briefing on volumes, urgent orders and any quality alerts. Edging operators work through a queue of jobs, each tagged with a barcode: scan, trace, edge, check size, pass to fitting. Fitters mount lenses, adjust screws and alignment, and place the job in the QC tray. QC inspectors verify each pair on the lensometer and under bright light, rejecting anything outside tolerance. Rejected jobs go back for rework, with the reason logged so patterns can be fixed. Packers clean, case and label finished glasses for courier pick-ups at fixed times. Productivity and accuracy are both tracked daily.
Working Conditions
Lab work is indoors, seated or standing at benches and machines, usually in air-conditioned or controlled environments because lenses and coatings are sensitive to dust and temperature. You will wear gloves and sometimes masks or lint-free clothing in coating areas. Edging produces fine lens dust and uses water coolant, so machine hygiene and PPE matter. Shifts may run around the clock in large facilities to meet delivery promises, particularly during sales and festive seasons.
Reading a Prescription: A Quick Primer for Lab Staff
Every lab job starts with the prescription, so learning to read it accurately is the first skill new joiners master.
| Term | Meaning | Why it matters in the lab |
|---|---|---|
| SPH (sphere) | Main lens power, minus for short sight, plus for long sight | Decides which lens blank is picked |
| CYL (cylinder) | Power to correct astigmatism | Must be oriented correctly when edging |
| AXIS | Direction of the cylinder, 1–180 degrees | A wrong axis is a common reason for rejection |
| ADD | Extra reading power for bifocals/progressives | Determines lens type and fitting height |
| PD | Pupillary distance | Sets where optical centres must sit in the frame |
QC inspectors compare the finished lens on a lensometer against these values and the tolerances set by the lab. Swapped right and left lenses, wrong axis and decentred lenses are the classic errors every new technician is trained to catch.
Common Quality Defects and How They Are Prevented
- Scratches – prevented by soft trays, gloves, careful handling and clean machines.
- Wrong size or loose lens – prevented by correct tracing and size checks before fitting.
- Chipped edges – prevented by correct edging programmes and machine maintenance.
- Coating marks – prevented by dust control and proper cleaning before coating.
- Misaligned frames – prevented by final alignment checks on a flat surface and from the side.
Productivity and Accuracy: How You Are Measured
Labs track jobs completed per hour, first-time-right rate (jobs passing QC without rework) and on-time dispatch. New joiners are usually given a learning period before full targets apply. The fastest way to grow is not speed alone but accuracy – a technician with a very low rework rate is trusted with complex jobs such as rimless and progressive fittings, which are more interesting and lead to senior roles.

Living Near a Manufacturing Facility
Industrial towns such as Bhiwadi, on the Rajasthan–Haryana border, host many factories and warehouses, so shared rooms, small eateries and transport for workers are easy to find. If you are relocating, ask whether the employer or staffing agency provides transport, canteen meals or hostel tie-ups; these make a real difference to your monthly savings. Keep money for the first month’s rent and food, as salaries are usually credited after the month closes.
Know Your Rights at Work
You should receive a written appointment letter naming your employer (company or staffing agency), your role, wage and hours; wages by bank transfer with a pay slip; PF and ESI where applicable; overtime pay as per rules; and free safety equipment. If something is missing, raise it with HR or the agency supervisor. National labour-law information is published by the Ministry of Labour at labour.gov.in.
Beware of Fake Warehouse Job Offers
Warehouse “packing jobs from home” and “direct joining with ₹2,000 registration” are common scams. Genuine employers do not charge for jobs. Report suspicious offers on Sanchar Saathi.
Frequently Asked Questions
Do I need optical knowledge to join the lab?
No, training is given; optical knowledge helps you grow faster.
Is lab work physically heavy?
It is mostly light bench work, but involves long hours of focus.
Are there night shifts?
Large facilities may run multiple shifts; ask during selection.
Can I move from the lab to a store job?
Lab experience is useful for store fitting roles; ask about internal transfers.
Is any fee required?
No.
Tips for Your First Weeks in the Lab
- Learn to hold lenses by the edges and always place them convex side up on soft trays.
- Read every job ticket twice – right and left, axis, PD – before you start.
- Ask seniors to show you how they check alignment; it is a visual skill that takes practice.
- Keep your bench clean; dust and loose screws cause most small defects.
- Note every rejection reason you receive and avoid repeating it.
Technicians who follow these habits usually reach full productivity within a few weeks and are trusted with complex jobs soon after.
Why Lab Experience Is a Real Trade
Independent opticians in every town need someone who can edge, fit and check lenses accurately. A few years in a high-volume lab gives you that skill – and some technicians later open their own optical workshop or join a smaller chain as lab in-charge.
Final Thoughts
Eyewear labs offer a rare thing for 10th/12th pass candidates: a skilled, indoor trade that can be learned on the job. Accuracy and patience are rewarded – and the skills travel with you.
