Question 1

Is FitLens a virtual try-on?

Accepted Answer

No. A virtual try-on renders frames over your face so you can judge how they look. FitLens measures your face in millimetres and tells you whether a 158 mm frame will actually fit. Looks are subjective; fit is a number.

Question 2

How accurate is the measurement?

Accepted Answer

Within about ±1.5 mm when you hold a standard card flat on your forehead. Every credit, debit and ID card is 85.6 mm wide by ISO standard, so the scan uses that known edge to convert pixels to millimetres.

Question 3

Do I need to download an app?

Accepted Answer

No. FitLens runs in your phone browser at woolet.co/en/fit. There is nothing to install, no account and no appointment. The scan takes about 20 seconds.

Question 4

Is my photo stored?

Accepted Answer

The camera frame is processed to extract measurements and is not kept as part of your profile. What we retain is the resulting numbers — face width, bridge width and pupillary distance — and only if you choose to save or email your result.

Question 5

What if the scan says I am outside the standard range?

Accepted Answer

It will say so plainly. Below 155 mm or above 161 mm, the signature 158 mm frame is the wrong frame and we route you to bespoke, which covers 145 to 172 mm. Above 172 mm we do not build a frame and we will tell you that instead of selling you one.

Question 6

Can I measure without the camera?

Accepted Answer

Yes. The manual route at /en/fit/manual walks you through your face width with a soft tape measure — no camera, no card. It gives you the same size recommendation, but only the face-width figure; for bridge width and pupillary distance you need the scan.

Question 7

Should glasses cover your eyebrows?

Accepted Answer

No. The top rim should sit at or just below your brow line. When your glasses cover your eyebrows, the bridge is usually too narrow for your nose: the frame rests on two points high on the nose, so the whole front lifts. A bridge that matches your nose, like Woolet's 21-22 mm keyhole bridge, lets the frame sit lower with your eyes centred in the lenses.

Question 8

Why do my glasses sit high on my nose?

Accepted Answer

The bridge is narrower than your nose. Instead of resting along the sides of the nose, the frame touches at two pinch points and leaves a gap above them. Measure your bridge width (FitLens does it in 20 seconds) and pick a frame with a matching bridge.

Question 9

What bridge width do I need for a wide nose?

Accepted Answer

Most standard frames use a 16-19 mm bridge. A wide nose usually needs 21 mm or more. Woolet frames use a 21-22 mm keyhole bridge, and Bespoke frames are cut to your measured bridge.
