Try Frame on Your FaceIntroducing the Celestine Browline Cat-Eye Eyeglasses, an elegant fusion of two enduring eyewear silhouettes. The structured browline creates definition across the upper frame, while the softly lifted cat-eye corners add a graceful feminine character for a distinctive yet wearable optical look.
Crafted with a lightweight metal construction and a semi-rimless lower profile, Celestine delivers an airy visual appearance without losing the structured character of the browline design. The polished Navy finish adds sophisticated depth, making the frame suitable for professional wardrobes, smart-casual styling, and vintage-inspired looks.
Celestine brings together the defined upper profile of browline eyewear and the elegant lift of a cat-eye frame. This combination creates a distinctive silhouette that adds structure around the eyes while retaining a graceful and feminine appearance.
The Navy metal finish gives the frame a sophisticated alternative to traditional neutral eyewear, while the semi-rimless construction keeps the overall profile visually light. It is an excellent choice for women who want classic-inspired eyewear with a contemporary interpretation.
The lightweight metal construction is designed for comfortable everyday wear, while adjustable silicone nose pads allow the frame to be positioned according to individual facial fit. The prescription-ready design can be paired with suitable optical lenses based on your vision requirements.
Nations Optics combines contemporary eyewear design with decades of optical experience. Our frames are selected with attention to design, prescription compatibility, everyday usability, and comfortable wear.
Prescription lenses can be personalized according to individual vision requirements, with suitable options available for single-vision, bifocal, and progressive prescriptions. Every complete eyewear order is prepared with attention to optical fitting and quality before dispatch.

Rimless frames require holes drilled directly into the lens to attach the frame. Regular lenses can easily crack or shatter at these drill points, which could be unsafe for your eyes.
Polycarbonate lenses are 10x more impact resistant than standard lenses — they won't crack during drilling or from accidental drops. They're virtually unbreakable and lightweight.
We use them for rimless frames purely for your safety and lens longevity — so you never have to worry about cracked or broken lenses.

Frequently asked
Rimless eyewear
Yes — and it is easier than you think. Nations Optics offers a free custom lens shape selector on every polycarbonate lens product page, built specifically for rimless frame wearers.
Rimless frames require holes to be drilled directly into the lens to hold the frame in place. Standard lens materials can crack or shatter at these drill points — which is why Nations Optics exclusively uses polycarbonate lenses for all rimless frames. Polycarbonate is 10x more impact resistant than regular lenses, virtually unbreakable, and handles precision drilling without weakening — keeping your eyes safe and your lenses lasting longer.
When you order a polycarbonate lens on any product page, you will see a "Choose Lens Shape" button. Select the shape that matches your rimless frame — Aviator, Butterfly, Rectangular, Oval, Square, and more — and our team will precision-cut your lenses to fit that exact shape. If your order also includes a rimless frame from our collection, the same shape is automatically applied and fitted for you.
Why polycarbonate only
Rimless frames require drilling directly into the lens. Only polycarbonate can handle this without cracking — keeping your lenses safe and durable.
Where to find it
On every polycarbonate lens product page, tap "+ Choose Lens Shape" before adding to cart. Pick your shape and we handle the rest.
No extra charge
Custom lens shape cutting is included at no additional cost. The price you see is the price you pay — shape selection is completely free.
Select your shape on the product page. If your order includes a rimless frame, the same shape is precision-cut and fitted directly into your frame before dispatch — all included in your order price.
