How It Works
The Lens King replaces the lenses in sunglasses you already own. Choose a lens for your exact frame, place your order, and snap the new lenses in — most fit straight out of the box, and every set is cut and finished in Italy.
Three steps to new lenses
1. Choose your lens
Find your frame by model, then pick a lens colour and finish — polarised, mirrored or photochromic. Every option lists its VLT% and ideal conditions, so you choose by performance, not guesswork.
2. Place your order
We cut your lenses to your frame’s specification in our Italian workshop. Free EU shipping over €50, and a 60-day perfect-fit guarantee on every order.
3. Snap them in
Your lenses arrive ready to install, with step-by-step instructions. No tools, no appointment — most frames take under a minute.
Installing your lenses
- Gently push the old lens out from the inside of the frame.
- Wipe the empty frame groove clean.
- Line up the new lens — match the curve and the notch to the frame.
- Press the lens in at the edges until it seats with a soft click.
A note on fit
Sunglass frames are produced in batches across different years and factories, and they are not always dimensionally identical — even within the same model. Because our lenses are cut to a precise specification, a small number may need light adjustment to seat perfectly. That is why every lens set ships with a fine-grit filing tool: not a workaround, but the honest way to guarantee a perfect fit across every version of your frame. Most lenses snap in with no adjustment at all.

Common questions
Do I need any tools to install them?
No. Your lenses arrive ready to install and most frames take under a minute by hand. The only tool you might use is the fine-grit filing tool included in the box, and only if a lens needs light adjustment.
What if my lenses don’t fit perfectly?
Most lenses snap in with no adjustment. If yours need a little, the included filing tool lets you fine-tune the fit — and you’re covered by our 60-day perfect-fit guarantee. If it isn’t right, we’ll make it right.
