Lens replacement — keep your frames
all-inclusive from €49
Fresh lenses in the frames you already love. With honest advice like we'd give our own mum.
Start Lens SelectionAll from Optika Della Spina, our independent lab — real opticians, not a chain.
Why people trust us with their glasses
Every frame is checked and handled by a real optician before any work. In the rare event one is ever damaged, you get a brand-new frame, free — no waiver, no fine print.
If your new lenses aren't right, we remake them until they are. If we still can't get it right within 30 days, you get every cent back.
Relenser is the sister company of Della Spina, the independent optical lab our founder started in 2019. Your lenses are cut by the same opticians, on the same equipment. Learn more about our laboratory

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:
Relenser is new. Our lab isn't — these are Google reviews of Optika Della Spina, the sister company that cuts every Relenser lens.
"The glasses were made quickly — I ordered on Tuesday and had them by Thursday. Reasonable price, and I'm very satisfied."
"I've been using their prescription glasses for years. The quality is exceptional, and the price is very affordable compared to other opticians."
"Excellent experience — quality progressive glasses with genuinely top-notch lenses."

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."
