S M OpticalsSpectacle Frame Manufacturer · India Sales Desk+91-8047836571
S M OpticalsSpectacle Frame Manufacturer · India Engineered to satisfy European Medical Devices Regulation (EU) 2017/745 Class I and international EN ISO 12870 benchmarks. Our export-ready product series deliver high mechanical endurance, pantoscopic precision, hypoallergenic skin-contact safety, and high-fashion aesthetics.
Sourcing optical frames for regulated Western and Asian markets necessitates full transparency across raw materials, chemical leaching tests, mechanical retention tolerances, and pantoscopic alignment stability. Below is our systematic test threshold matrix.
| Standard Directive | Testing Parameter | Tolerance / Metric Threshold | Clinical & Commercial Benefit |
|---|---|---|---|
| EN ISO 12870:2018 Clause 4.3 | Physiological Compatibility | Zero cytotoxic or skin-irritation reaction | Ensures non-allergenic wear for high-sensitivity end-consumers. |
| BS EN 16128:2015 (REACH) | Nickel Release from Metal Components | < 0.5 μg/cm²/week limit | Direct skin-contact metal components will not induce contact dermatitis. |
| EN ISO 12870 Clause 4.8 | Mechanical Endurance (Hinge Flex) | 25,000 continuous opening/closing cycles | Guarantees hinge barrel alignment and screw retention over years of wear. |
| ISO 12870:2018 Clause 4.9 | Thermal Stability & Bridge Retention | Deformation ≤ 1.5% after 60°C heat soak | Maintains optic center interpupillary distance (PD) calibration without slippage. |
| EU 2017/745 MDR | Medical Device Class I Documentation | Full technical file & Declaration of Conformity | Hassle-free customs clearance for EU-based medical device distributors. |
The iconic cat eye optical frame has shifted from vintage styling to a high-precision biomechanical instrument. Our engineering department designs frontals to distribute downward mass across the nasal dorsum while elevating feminine cheek contours through measured angularity.
By computing varying bridge radii from 16mm to 19mm with anatomical stepped chamfers, our frames prevent deep dermal red marks on the bridge while keeping progressive lens focal channels precisely centered with ocular pupils.
Combining dual-hue and tri-layer cellulose acetate sheet blocks under regulated autoclave compression eliminates microscopic air pockets, ensuring edge polish clarity along the extended cat eye crest and upper rim perimeter.
Every frame incorporates a standardized 1.8mm high-precision V-groove calibrated to secure thick negative diopter lenses (up to -8.00D) and complex progressive optics without front-rim pop-out during seasonal temperature flux.
As institutional eyewear procurement shifts toward supply chain transparency, carbon accountability, and adaptive stock fulfillment, optical brands must align their inventory roadmaps with emerging technological paradigms.
Traditional diethyl phthalate plasticizers are being replaced with bio-derived triethyl citrate formulations. Procurement directors across the EU and North America are prioritizing frames made from renewable wood pulp and cotton lint with certified bio-degradability ratings exceeding 60% within 180 days under ISO 14855 standards.
Modern cat eye frames are shifting from heavy thick castings to ultra-thin beta-titanium and polymide hybrids. These designs offer tensile memory retention, corrosion immunity against human perspiration, and frame total chassis weights below 14 grams, optimizing wearability for extended screen hours.
Gone are the days when distributors were locked into 5,000-piece minimums for single molds. Flexible multi-axis CNC routing systems allow factories to run private label capsules of 300 to 500 units per colorway, empowering brands to respond to fast seasonal shifts without burdensome deadstock inventory.
Operating as a verified, GST-compliant manufacturing hub (GST No. 27AILPM7839G1ZQ) established since 2017, our enterprise infrastructure bridges precision optical craftsmanship with dependable wholesale production. Guided directly by our core management—including concern person Dharamchand Maheshwari—our production team coordinates custom model assortments, strict dimensional tolerances, and planned export packaging.
We supply leading retail chains, regional optical laboratories, and bulk distributors across polymide, high-nickel alloy, Mazzucchelli-grade acetate sheet, and TR-90 frames, backing every shipment with an outstanding 88% first-contact inquiry response rate.
Direct production oversight eliminates redundant trading markups, ensuring competitive unit margins for wholesale partners.
Every cat eye frame undergoes screw-torque stabilization, pantoscopic angle profiling, and surface polishing checks before boxing.
High-precision laser marking for temple inside logos, CE symbols, model sizing, and export UPC barcoding.
Clear, direct answers regarding testing compliance, ordering logistics, OEM personalization, and lens glazing parameters.
