Buying glasses online has changed dramatically over the last few years. One of the biggest improvements has been virtual try-on technology. It allows you to see how a frame may look on your face before you buy, helping you narrow down styles from the comfort of your home.
However, virtual try-on is only one part of choosing the right glasses. It can help with style, but it cannot accurately judge bridge fit, overall comfort, prescription suitability or how thick your lenses will be. This guide explains exactly what virtual try-on can and cannot do, so you can use it with confidence.
The simple rule
Use virtual try-on to choose a style. Use frame measurements, prescription guidance and professional advice to choose the right frame.
How virtual try-on works
Virtual try-on uses your device's camera to place a digital model of the frame onto your face. Modern systems estimate facial landmarks such as your eyes, nose and ears to position the frame realistically.
Style
See whether you prefer round, rectangular, cat-eye, aviator or oversized frames.
Colour
Compare black, tortoise, crystal, gold and silver finishes.
Fit
It cannot accurately judge bridge fit, comfort or prescription suitability.
Think of virtual try-on as a mirror, not a fitting appointment.
It is brilliant for eliminating styles you don't like. It should never be the only reason you choose a frame.
What virtual try-on can tell you
- Whether you like the frame shape.
- How the frame colour works with your complexion.
- Whether you prefer a bold or subtle style.
- How different sizes appear visually.
- Which shortlist of frames you would like to compare.
