Pick a frame, choose “Add Prescription”, select your lens options, and upload your prescription. If you don’t have PD (pupillary distance), we’ll help you measure it after checkout.

We can accommodate most single-vision and progressive prescriptions. Very strong prescriptions or high wrap frames may require specific lens materials or frame styles. Our opticians review every order and will confirm feasibility before we start.

Yes — many sport/wrap styles support prescription lenses. In some cases we’ll recommend Trivex or high-index materials, flatter base curves, or an insert to maintain optical performance. We’ll advise the best route for your Rx and sport.

Single-vision is ideal for distance (driving, outdoor sports). Progressives add seamless near/intermediate zones for dashboards, phones, or maps. If you prefer a visible line, flat-top bifocals are also available in many tints.

• Polycarbonate: Lightweight, impact-resistant—great for most prescriptions.
• Trivex: Exceptional clarity + impact resistance; excellent for wrap/sport frames.
• High-index: Thinner/lighter for strong prescriptions.

Polarization is optional but strongly recommended for cutting glare from water, snow, and pavement. It’s ideal for driving, fishing, and boating. Note: some LCD screens (dash displays) can appear darker with polarized lenses.

Standard photochromics are UV-activated and may darken less behind a windshield. We also offer sun-optimized or fixed-tint options if maximum in-car darkness is your priority.

• Driving: Neutral gray or brown (polarized) for comfort and true color.
• Fishing/Water: Polarized gray/blue or brown/green to cut surface glare.
• Golf: Brown/amber or rose-copper to enhance contrast on greens.
• Cycling: Brown/rose for variable light, mirror for bright days.
• Shooting: Purpose tints (e.g., orange/copper/rose) tuned to background and light—available in Rx.

Yes. We offer mirrored, flash, and gradient tints on many lens colors and materials. Mirrors reduce surface brightness and add style without changing the underlying tint function.

Yes — premium back-surface AR reduces reflections from behind you (e.g., sunlight entering around the frame) and improves clarity. It also helps keep lenses cleaner.

Upload your Rx during checkout or email it after ordering. If your PD isn’t listed, we’ll send an easy guide to measure it accurately or coordinate with your eye care provider.

Most orders ship in 10–14 business days depending on lens complexity and frame availability. We’ll keep you updated at each step.

Prescription lenses are custom-made and non-refundable, but we offer a one-time lens remake to get things right. Non-prescription items follow our standard 30-day return policy for unused products.

Yes — HSA/FSA cards are typically accepted for Rx eyewear. For vision insurance, we can provide an itemized receipt for potential out-of-network reimbursement.

We verify PD/OC placement, base curve, and lens thickness during fabrication. For wraps, we select suitable materials and geometry to maintain clarity and minimize peripheral distortion.

Rinse dust first, then use lens cleaner and a microfiber cloth—no paper products or harsh chemicals. Frames are covered by the brand’s warranty; our premium AR options include a manufacturer warranty against defects.
