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.
