What you are really asking

“If it's cheaper, are the lenses worse?”

NO! Every € we save comes from how we run the business, never from your glasses.

We use the exact same quality the big brands sell, made by the major lens manufacturers, just white-label.

What's actually cheaper is everything around the lens:

  1. 01 Sourcing the lenses directly from factories.
  2. 02 We're online-only, so you're not paying for a high-street store on every pair.
  3. 03 A fairer margin, made at our lab's scale.

"What if you break my frames?"

Then you get a new frame, free. Used frame — pick a brand-new one from our collection. New frame — we buy you the exact same pair. That's the 100% guarantee.

"What if you lose my glasses in the post?"

Tracked door-to-door, both ways. You always know exactly where they are.

"What if the prescription comes back wrong?"

A real optician checks it before we cut a single lens. No wrong-Rx surprises.

"What if something's off and nobody answers?"

You reach a real person — by email or phone. No ghosting, no black box.

"What if it drags on for weeks, like the others?"

1 working day for single vision, about 4 for progressives. Plus tracked shipping — not months.

"What if my prescription is too strong for you?"

We make the ones the high street turns away. High astigmatism or a strong Rx — just ask.

Marin in the lab

From the founder

"I'm Marin. I founded Della Spina, an independent optical lab in Slovenia, in 2019 — we've made 73,000+ pairs of glasses since. I started Relenser, its direct-to-you sister company, because I kept watching people bin frames they loved just because their prescription changed — and overpay for the privilege. We treat your glasses the way we'd treat our mum's: tested before we touch them, fair price, zero upselling."

Questions, answered

Every frame is checked and handled by a real optician before any work, so your frames are safe in our hands. And in the rare event one is ever damaged, we make it right: a used frame is replaced with a brand-new one from our collection, free of charge — a brand-new frame, we buy you the exact same model again.

You're covered by our 30-day money-back guarantee. If your new lenses aren't right, we remake them until they are — and if we still can't get it right within 30 days, you get a full refund. No waiver, no fine print.

Single-vision lenses are usually fitted in 1 working day after we receive your frames; made-to-order lenses (progressive, occupational, sunglass) take about 4. Add tracked shipping both ways — we send your glasses back the same day the lenses go in.

You pay for shipping once — one flat fee that covers both directions. We email you a prepaid, tracked GLS label; use your own packaging and drop the parcel off. Your glasses travel tracked both ways, and you never pay anything at the counter.

Ideally yes. If you don't have it handy, send a photo of your current lenses or your last prescription and we'll guide you — or tell you the easiest way to get an up-to-date copy.

Yes — prescription or non-prescription sun lenses, tints, polarised and photochromic (light-adaptive) lenses are all available.

Everything: anti-glare and scratch-resistant coatings, a hydrophobic layer, and expert fitting. One all-inclusive price — no add-ons, no upsells.

Absolutely. We don't sell frames — bring any brand, bought anywhere: online, from your optician, or abroad.

We get it — that's a real worry. Your frames are tracked end to end, single-vision turnaround is fast, and a real person is reachable the whole time — so you're never left wondering where your glasses are.
