The oldest problem with buying glasses online is that a frame photographed on a stranger tells you almost nothing about how it will look on you. Virtual try-on exists to close that gap: you supply a photo, and the frame is placed on your face rather than on a model's.
How the placement works
The useful version of this is not a sticker. The system finds facial landmarks in your photo — the corners of the eyes, the bridge of the nose, the outer edges of the face — and uses the distance between them to work out the scale of your face in the image. The frame is then drawn at its own real size relative to that scale, and rotated to match the angle of your head.
That distinction is the whole point. A frame pasted on at a fixed size makes every frame look equally wide, which is precisely the question you are trying to answer. A frame scaled from real measurements means a 145mm-wide frame and a 132mm-wide frame look different on your face, because they are.
What it answers well
- Whether the width suits your face. The single most visible fit property, and the easiest one to judge on screen.
- Where the top bar sits against your brows. The detail that decides whether a frame looks composed or slightly off, and one most people can spot instantly once told to look.
- Colour against your own colouring. A tortoiseshell that looks warm on a studio model can read very differently on your skin tone and hair.
- Shape, honestly. Whether you actually like round frames on your own face, rather than in theory.
What it cannot tell you
- Comfort. No image shows you how a frame distributes weight, whether the temples press, or how nose pads sit after four hours.
- Exact bridge fit. A 2D photo cannot see the height and shape of your nose bridge, which is what determines whether a frame sits where the render shows it.
- Material and finish in the hand. The difference between a light titanium frame and a substantial acetate one is mostly a physical sensation.
- Lens thickness in a strong prescription. Edge thickness depends on your correction and the frame's size, and it is not part of the render.
Use it with the numbers, not instead of them
Try-on settles what a frame looks like; the measurements settle whether it fits. Check the total frame width and bridge width on the product page against a pair you already own — the numbers printed inside your glasses covers how to read them in about two minutes.
Getting a usable photo
- Face the camera straight on, with your whole face in the frame and your eyes level.
- Use even light from the front. Strong side light or a bright window behind you makes landmarks harder to find and the result less accurate.
- Push your hair back off your face and take existing glasses off first.
- Keep a neutral expression — a wide smile moves the cheeks enough to shift the landmarks.
A photo you supply is used to render the frames and nothing else; what we do with it is set out in our privacy policy.
