1) Place the glasses on
2) Put phone camera onto selfie mode (Front camera)
3) Hold your phone at arms length, positioning your face in the centre of the image
IMPORTANT: Your face needs to be positioned square on in the image. So that you can see your right and left sides of your face equally.
4) Position your thumb over the button to take a photo. Look directly towards the black line in the middle of the glasses then take your photo. See the images below for the correct positioning of your face in the image.
NOTE: We delete all images once pupil distances have been taken. But please feel free to crop your photo before sending should you wish.
