Table of Contents
Part 1: Returns and Refunds
|
What is Navi Eyewear’s return policy? Navi Eyewear offers a 30-day return policy. Sunglasses must be returned in their original, unworn condition — exactly as received, undamaged, and in their original packaging. The 30-day window begins on the date of delivery. |
|
What does ‘unworn’ mean for returns? Unworn means the sunglasses have not been worn outdoors or used in any way. They should be in the same condition as when they arrived: no scratches on the lenses, no marks on the frames, no signs of outdoor use, no evidence of cleaning or contact with sweat, sunscreen, or salt water. Think of it the same way as returning unworn clothing with tags attached: the return window is for buyers who decide before use that the product is not right for them, not for wear-and-return. |
|
What cannot be returned? Sunglasses that have been worn outdoors, used at the beach, taken on a run, worn while driving, or subjected to any normal outdoor use do not qualify for return under the standard return policy. If a worn pair has developed a quality issue or has been damaged through normal use, that is covered by the free replacement provision — not the return policy. |
|
How do I initiate a return? Contact Navi Eyewear within 30 days of delivery. You can reach the team by email atinfo@navieyewear.comor through the contact form at navieyewear.com. Include your order number and the reason for the return. The team will respond with return instructions and the next steps. |
|
How long does a refund take? Once the returned item is received and confirmed to be in original unworn condition, the refund is processed. Refund timelines vary depending on your payment method and bank processing times. Contact the team if you have not received confirmation within a reasonable timeframe after return receipt. |
Part 2: Replacements
|
Does Navi Eyewear offer free replacements? Yes. Free replacements are part of the Navi Eyewear ownership experience. If a pair you have been wearing develops a quality issue or is damaged through normal use, Navi will replace once at no cost . Customer just needs to cover current shipping and handling fees. |
|
What qualifies for a free replacement? Pairs that have been worn and have experienced quality issues — lens delamination, coating failure, frame hardware failure, hinge failure under normal use — or physical damage through normal outdoor use. The replacement provision is designed for the real-world reality that sunglasses used outdoors will eventually experience damage. |
|
How do I request a replacement? Contact Navi Eyewear by email atinfo@navieyewear.com or via the contact form at navieyewear.com. Include your order number and a description of the issue. The team will confirm and process the replacement. |
|
Is the free replacement different from the return policy? Yes. The return policy applies to unworn sunglasses within 30 days of delivery. The free replacement provision applies to worn sunglasses that have been used and have developed issues or damage. These are two separate provisions covering two different post-purchase scenarios: deciding before use vs wear-and-damage. |
Part 3: The Buy 1, Get 3 Free Offer
|
How does the Buy 1, Get 3 Free deal work? Browse the Navi Eyewear collection atnavieyewear.com/collections/polarized. Add any four pairs to your cart. The Buy 1, Get 3 Free discount auto-applies at checkout — no code needed. The total is $119 for four pairs. Free shipping is included. |
|
Do all four pairs in the deal have the same specification? Yes. Every pair in the Navi collection is UV400 certified polycarbonate with quality-controlled polarized lenses, oleophobic coating, anti-saltwater coating, TR90 nylon frames, and stainless 5-barrel hinges. The Buy 1, Get 3 Free deal provides four pairs of the same complete specification — you choose four styles, not four tiers. |
|
Can I mix and match styles in the four-pair deal? Yes. Add any four styles from the collection to your cart and the Buy 1, Get 3 Free discount applies regardless of which specific frames you choose. |
|
Is free shipping included in the deal? Yes. Free shipping is included with the Buy 1, Get 3 Free deal. No minimum order beyond the four-pair bundle is required for free shipping. |
Part 4: Sizing and Fit
|
Where can I find the frame dimensions for each style? Frame dimensions — lens width, bridge width, and temple length — are listed on each individual product page at navieyewear.com. Navigate to the specific frame you are interested in to find the measurement details for that style. |
|
How do I read the frame measurement numbers? The three measurements listed for each frame are: lens width (the horizontal width of one lens in millimetres), bridge width (the gap between the two lenses at the nose in millimetres), and temple length (the length of each arm from hinge to tip in millimetres). The total frame front width — the width that determines whether the frame fits your face — is calculated as (lens width × 2) + bridge width. For a frame listed as 52-17-140, total front width = (52 × 2) + 17 = 121mm. |
|
How do I know if a frame will fit my face? Measure your face width at the widest point (typically across the cheekbones) and compare to the total frame front width calculated from the product page dimensions. Frames within 5–10mm of your face width typically fit proportionally. For the complete guide to sunglass fit including what each measurement means and the fit checklist for different face types, seehow to tell if sunglasses actually fit. |
|
Can I return a pair if the fit isn’t right? Yes — if you have not worn the pair outdoors, you can return it within 30 days of delivery under the standard return policy. For fit assessment: try the pair on at home before taking them outdoors to confirm the fit is right. If the fit is not right and the pair has not been worn outside, return it within 30 days. |
|
Do Navi sunglasses come in different sizes? Frame dimensions vary by style. Review the specific measurements on each product page to find the fit that matches your face geometry. If you have specific questions about fit for a particular face shape or nose bridge type, the sizing guidance in the frame measurement guides on the Navi blog covers the full range of fit scenarios. |
Part 5: Lens Care
|
How should I clean Navi Eyewear lenses? Use a clean microfibre cloth and, if needed, a small amount of mild soap and water or an optical lens cleaning spray. Rinse with clean water, then wipe dry with the microfibre cloth. Oleophobic coating on Navi lenses makes most fingerprints and smears removable with a single dry microfibre wipe in everyday conditions. |
|
Can I use my shirt to clean the lenses? Not recommended. Shirt fabric — particularly cotton and synthetic blends — contains embedded dust particles, lint, and abrasive fibres that scratch lens surfaces with repeated rubbing. Microfibre cloths use ultra-fine fibres that lift and trap contaminants without scratching. A microfibre cloth wipe takes the same time as a shirt wipe and produces no surface damage. |
|
What should I avoid when cleaning the lenses? Avoid: acetone (nail polish remover), alcohol-based sprays at high concentrations, household glass cleaner (many contain ammonia which can damage lens coatings), rough paper towels or toilet paper, and abrasive fabrics. These can strip or damage the oleophobic coating and potentially degrade lens surface quality over time. For the full lens maintenance guide including how to preserve all lens coatings, seehow to clean and care for sunglasses. |
|
My lenses are scratched. Does this affect UV protection? For polycarbonate lenses, surface scratching does not affect UV protection. Polycarbonate provides inherent UV400 protection throughout the lens material — not through a surface coating — so scratches that affect the outer surface do not reduce UV blocking. Surface scratches do reduce optical clarity over time, which eventually affects visual quality. Heavily scratched lenses are a reason to request a replacement, not a UV protection concern. |
|
Can I use water to clean my Navi sunglasses? Yes. Rinsing with clean lukewarm water is effective for removing dust, salt deposits, and loose debris. After rinsing, dry with a microfibre cloth. Avoid hot water, which can weaken frame adhesives and lens mounting over time. For marine and coastal use specifically, rinsing with fresh water after salt exposure is the primary maintenance practice that extends lens and frame life most effectively. |
Part 6: Frame Care
|
How should I store my Navi sunglasses? Store in a soft pouch when not in use. Navi’s TR90 frames are highly resilient to physical stress — they can be packed without a hard case and will recover from deformation. For the lenses, a soft pouch prevents direct contact between lens surfaces and abrasive materials in bags and pockets. Avoid storing lens-down on hard surfaces. |
|
Can TR90 frames be adjusted? TR90 nylon is a flexible material that can be gently adjusted for a more comfortable fit. Gentle warming — running warm (not hot) water over the temple tips or the nose area for 20–30 seconds — makes the material more pliable for adjustment. Most minor fit adjustments for temple bend angle can be made this way. For significant fit issues, an optician can perform more precise adjustments. |
|
The hinge on my sunglasses is loose. What should I do? Navi frames use stainless 5-barrel hinges designed for long-term durability. If a hinge becomes loose over extended use, a small eyeglass screwdriver can tighten the hinge screw. Eyeglass repair kits are widely available in pharmacies for under $5. If the hinge has a more significant issue, contact the Navi team atinfo@navieyewear.com for replacement guidance. |
|
Can I wear Navi sunglasses in the water? Yes. Navi lenses include anti-saltwater coating specifically for marine and coastal environments. The TR90 frames and stainless hardware resist corrosion in salt and fresh water. For any water activity where losing the glasses is a risk — surfing, kayaking, diving, open water swimming — an eyewear retention strap or cord attached to the temple tips is recommended. Navi does not supply these as standard but they are widely available at outdoor and sports retailers. |

Frequently Asked Questions
Can I return Navi sunglasses if they don’t fit?
Yes — if the pair has not been worn outdoors. Try the frames on at home before taking them outside. If the fit is not right before any outdoor use, you have 30 days from delivery to return them in original unworn condition. To initiate, emailinfo@navieyewear.com with your order number.
What happens if my Navi sunglasses are damaged?
If a worn pair develops a quality issue or is damaged through normal outdoor use, contact the team atinfo@navieyewear.com for a free replacement. The free replacement provision covers wear-and-damage scenarios that the standard return policy does not.
Do Navi sunglasses come with a case?
Navi sunglasses are delivered in packaging appropriate for safe transit. The TR90 frames are highly resilient and can be stored in a soft pouch for daily carry. If a storage case is not included with your order, a soft microfibre pouch — widely available at optical and sports retailers — provides effective lens and frame protection for daily use.
How do I find out the dimensions of a specific Navi frame?
Frame dimensions (lens width, bridge width, temple length) are listed on each individual product page at navieyewear.com. Navigate to the specific style you are considering to find its measurements. For help interpreting the measurements and applying them to your face geometry, seehow to tell if sunglasses actually fit.
Can I clean Navi lenses with lens wipes?
Pre-moistened optical lens wipes are generally safe for Navi lenses, provided they are alcohol-free or contain only very low concentrations of alcohol. Check the lens wipe ingredients before use. Wipes with high alcohol content, acetone, or harsh surfactants can damage the oleophobic coating over time. A clean microfibre cloth with mild soap and water remains the safest everyday cleaning method.
Do Navi sunglasses protect against UV through the side gaps?
The lens itself provides UV400 protection across the area it covers. The frame design and fit determines the peripheral coverage geometry. Frames that fit close to the face provide better peripheral UV protection than frames that sit away from the face with large gaps at the brow and temples. For the full discussion of how frame coverage affects UV protection, seethe complete guide to UV eye protection.
Are Navi sunglasses suitable for children?
Navi’s standard collection is adult-sized eyewear. For children requiring age-appropriate sizing and frame construction (rubber straps, toddler-specific frames), specialist children’s eyewear brands are more appropriate. The complete guide to UV protection for children including what to look for in children’s sunglasses is inthe complete guide to sunglasses for kids and teenagers.
