Buying prescription glasses online: the complete step-by-step process

Buying prescription glasses online feels daunting the first time: the prescription, the lenses, coatings, measurements… Relax — the process at Gafas Canarias is designed so you cannot go wrong, and here we break it down from click to letterbox.

Step 1 · The frame (and the sizing trick)

Choose from prescription frames — or sunglasses: most can be glazed too. Worried about size? Grab your current glasses: inside the temple you will find something like 52□18 140. That first number is the lens width — look for frames within ±2 mm of yours and the fit will feel familiar.

Step 2 · The lens configurator

Step 3 · Your prescription, no weird translations

Copy the prescription exactly as issued: sphere, cylinder, axis per eye, plus addition for progressives. Is it older than 1-2 years? Get re-tested first — prescriptions drift, and glazing lenses to an outdated script is money wasted. Unsure about your PD (pupillary distance)? Message us: there are several simple ways to obtain it and we will guide you.

Step 4 · Glazing, shipping and warranty

Lenses are glazed and verified, then your order ships — tracked delivery; timing confirmed according to availability and destination to the Canaries and mainland Spain once assembled. Everything carries a 2-year warranty and real after-sales service: if something feels off when you first wear them, it gets sorted — that is what we are here for.

One very Canarian extra: any prescription frame can become prescription sunglasses with one click in the configurator.
