The framework governing the use of quenix.online and the relationship surrounding our eyewear factory, retail boutique, custom-made eyewear, wholesale supply, private-label production, and international export operations.
These Terms of Use govern access to and use of the website quenix.online, operated by I M SANTOS OTICA LTDA. By accessing or using this website, the visitor acknowledges having read, understood, and accepted these Terms, as well as the applicable Privacy Policy.
This website presents the institutional and commercial profile of I M SANTOS OTICA LTDA, operating under the Quenix brand — an optical atelier and eyewear manufactory based in Caruaru, Pernambuco. The website provides information about our four operational channels — eyewear factory, retail boutique, wholesale, and international export — and operates as a digital extension of our physical atelier, enabling individual patients, optical chains, independent opticians, brand operators, and international counterparts to submit orders and request quotes.
Quenix operates integrated optical atelier and eyewear manufactory operations across two departments — Operation A (Retail & Prescription: prescription eyewear, custom made-to-measure, sunglasses & fashion, optical services) and Operation B (Factory & Export: frame manufacturing, wholesale distribution, international export, private-label & custom production). Our work spans retail eyewear sale, prescription eyewear dispensing, in-house frame manufacturing, custom-made (sob medida) eyewear production, wholesale distribution, private-label/OEM production, and international export. This website serves as a point of institutional presentation, online commercial contact, and digital extension of the physical atelier — all engagements are formalized through written commercial agreements, point-of-sale transactions, or structured purchase orders.
Eyewear retail, prescription dispensing, manufacturing, wholesale distribution, and export operations in Brazil are subject to comprehensive sanitary and regulatory requirements — including but not limited to oversight by ANVISA (Agência Nacional de Vigilância Sanitária) applicable to eyewear and prescription lenses as health products, state and municipal Vigilância Sanitária authorities, the Conselho Regional de Óptica e Optometria rules where applicable governing optical professional responsibility, and the requirements applicable to eyewear as a regulated health product. Export operations are additionally governed by SECEX (Secretaria de Comércio Exterior), Receita Federal customs authority, and the regulatory and customs requirements of importing countries — including any product registration or sanitary certification required by destination-country authorities. Our operations adhere to applicable regulatory standards, and eyewear traceability is maintained as required by law.
Specific commercial engagements — including scope, products, quantities, deadlines, delivery terms, payment terms, and remuneration structure — are formalized through written commercial agreements, structured purchase orders, or point-of-sale transactions in the physical atelier. Walk-in retail purchases are governed by standard commercial terms communicated at the point of sale and applicable Brazilian retail consumer law. Prescription eyewear dispensing requires a valid prescription presented in line with applicable Brazilian regulations and is subject to verification. Wholesale, private-label, and B2B engagements are formalized through structured supply contracts, and export engagements are formalized through structured international commercial contracts in line with applicable trade and customs regulations.
Submitting an order, inquiry, or form through this website does not create an automatic engagement, guarantee acceptance of the order, confirm pricing, or establish a contractual obligation. All engagements are subject to internal review, manufacturing capacity availability, sanitary and regulatory compliance verification, customer creditworthiness assessment (when applicable), prescription verification (where required), and formal agreement between the parties through appropriate written contracts or in-store transactions. Definitive engagement terms — including pricing, production timeline, and product availability — are confirmed exclusively through written commercial agreements, structured purchase orders, or at the physical point of sale.
Prescription eyewear is dispensed exclusively against valid prescriptions presented in line with applicable Brazilian regulations. Prescriptions must be issued by a qualified ophthalmologist or optometrist authorized to issue eyewear prescriptions under Brazilian law. The verification of the medical or optometric examination, the issuance of a valid prescription, and the periodic review of vision parameters are the patient's responsibility — the atelier does not provide medical examinations or vision-correction diagnoses, and provides eyewear dispensing strictly within the scope of an optical retail and manufacturing operation. The atelier may refuse dispensing when the prescription does not meet the regulatory requirements, when there are concerns about the prescription's validity, or when dispensing would conflict with applicable optical professional responsibility standards.
Custom made-to-measure eyewear (sob medida) — including bespoke prescription glasses, personalized frame designs, and any eyewear produced to specific customer measurements or specifications — is produced under specific written agreements that capture the requested specifications, frame dimensions, lens parameters, materials, color, finishing, and any other element that distinguishes the order from off-the-shelf product. Custom orders are subject to manufacturing tolerances standard in the eyewear industry and are produced exclusively for the requesting customer based on the agreed specification. Approval of the final specification before production begins is the customer's responsibility, and changes after production has started may incur additional charges or be impossible without restarting the production cycle.
Frame manufacturing — including in-house production of acetate frames, metal frames, and combination materials — is subject to standard industry tolerances for variations in color, finishing, polishing, dimensions, and material consistency. Eyewear delivered to the customer is expected to fall within these standard tolerances and is not considered defective when variations remain within them. Custom dyes, hand-finishing, and artisanal production may produce small batch-to-batch variations that are inherent to manufacturing of this kind and not a basis for rejection. Specific tolerance specifications for custom orders are agreed in writing as part of the production specification.
Prescription and non-prescription lens supply includes a range of lens types (single-vision, bifocal, multifocal, progressive) and lens treatments (anti-reflective coating, photochromic transition, polarized lenses, blue-light filtering, scratch resistance, hydrophobic coating). Lens performance and durability follow the manufacturer's stated specifications and are subject to normal wear and care requirements. Lens warranties follow the lens manufacturer's warranty terms, which are transmitted to the customer at the point of sale or installation. Treatment durability is influenced by use conditions, cleaning practices, and exposure to chemicals or extreme environments — matters that are the customer's responsibility to manage.
Eyewear is covered by warranties applicable in line with the Brazilian Consumer Protection Code and the specific warranty terms of frame and lens manufacturers. Frame warranties typically cover manufacturing defects in materials and workmanship under normal use, with terms specified at the point of sale. Lens warranties cover manufacturing defects and may cover treatment durability per the lens manufacturer's stated terms. Warranty exclusions typically include damage from accidents, misuse, exposure to chemicals or extreme conditions, unauthorized modifications, normal wear, and any cosmetic deterioration that is inherent to use of the product. Warranty claims are evaluated by the atelier in line with applicable terms.
The atelier does not provide medical examination services or vision-correction diagnoses. The medical or optometric examination required to determine vision-correction needs and to issue a valid prescription is the responsibility of a qualified ophthalmologist or optometrist authorized under Brazilian law. The atelier provides eyewear dispensing, frame fitting, lens mounting, and the optical-retail services associated with executing a prescription that has been validly issued by a qualified professional. Vision-related health concerns require professional medical evaluation — the atelier's role is exclusively that of an optical retailer and eyewear manufacturer.
Private-label and OEM/ODM eyewear production for brand operators is governed by specific written contracts that capture: the brand specifications, frame designs, materials, finishing, colorways, packaging, labeling, intellectual property ownership of designs, confidentiality obligations, minimum order quantities, lead times, and quality standards. Intellectual property in proprietary frame designs contributed by the brand operator remains the property of the brand operator unless otherwise agreed in writing, and is treated under strict confidentiality. The atelier will not produce eyewear bearing third-party trademarks without proper authorization from the trademark owner, and brand operators warrant that they hold the trademark rights and intellectual property authorizations required for the production they commission.
Eyewear export shipments are subject to specific contractual terms covering: destination country eyewear regulations and import requirements, sanitary certification at origin if applicable, customs documentation, freight terms (FOB, CIF, or other Incoterms agreed in writing), payment instruments, currency, and risk transfer at agreed loading points. The atelier is responsible for compliance with Brazilian export regulations, applicable sanitary certifications at origin, and dispatch in line with the agreed Incoterms. Import-side regulatory compliance, registration of the eyewear products with the destination country's regulatory authority (where required), customs clearance at destination, applicable duties, taxes, and any product-conformity certifications required at destination are the responsibility of the importing party unless otherwise agreed in writing. Export contracts are governed by the specific written agreement between the parties.
I M SANTOS OTICA LTDA shall not be liable for indirect or consequential damages, business losses, lost profits, missed deadlines beyond the atelier's reasonable control, third-party logistics failures, lens or frame manufacturer defects (covered under manufacturer warranty), customs delays, force majeure events affecting supply chains or transport, or losses resulting from misuse of the website or eyewear product. The atelier is not liable for vision-correction outcomes resulting from prescription parameters provided by the patient — the accuracy of the prescription is the responsibility of the prescribing professional, and the atelier executes the prescription as supplied. Commercial responsibilities are governed by the terms of the specific engagement agreement, the applicable Consumer Protection Code (Lei nº 8.078/1990) for retail relationships, and the international commercial framework for export operations.
Wholesale, private-label, and export commercial relationships routinely involve information that requires real commercial discretion — volume pricing, supply contracts, brand-specific frame designs, OEM/ODM specifications, customer-specific requirements, and commercial arrangements not intended for public disclosure. All such information is treated under strict commercial confidentiality, and is not disclosed externally except in the limited circumstances defined in commercial contracts or required by applicable law. Specific confidentiality obligations and non-disclosure agreements (NDAs) are formalized in written supply agreements when the customer requires.
The relationship between the atelier and individuals receiving eyewear products at retail is protected by the Brazilian Consumer Protection Code (Lei nº 8.078/1990), including rights related to clear product information, product quality, sanitary safety, proper communication of conditions, and the consumer protections that apply to optical retail in Brazil. Specific limitations on the right of regret apply to custom-made and personalized eyewear — bespoke prescription glasses produced to specific patient parameters and personalized/sob-medida frames are produced exclusively for the requesting customer based on individual specifications, and as such, in line with Brazilian consumer law applicable to personalized goods, are not subject to the standard right of regret applicable to off-the-shelf products. Defective custom eyewear is handled in line with applicable warranty and consumer-protection rules.
These Terms of Use shall be governed by and interpreted in accordance with Brazilian law, including the Brazilian Civil Code, the Consumer Protection Code (Lei nº 8.078/1990), applicable sanitary regulations (ANVISA, Vigilância Sanitária at federal, state, and municipal levels), the Conselho Regional de Óptica e Optometria rules where applicable, Brazilian export and customs regulations (SECEX, Receita Federal), and the Lei Geral de Proteção de Dados (LGPD). Any disputes arising from the use of this website shall be submitted to the jurisdiction of the courts of Caruaru, State of Pernambuco, Brazil, except where otherwise required by law — including the consumer's right, under the Consumer Protection Code, to bring a claim in their own domicile, and except where international export contracts establish a specific arbitration or jurisdiction clause agreed between the parties in writing.
These Terms of Use may be updated at any time to reflect changes in our operations, applicable law, or website content. The version published on this page is always the current applicable version. Continued use of the website after any update constitutes acceptance of the revised Terms.
