Finding your fit

Start from the glasses you already wear

Do they feel too wide or too narrow? Do they slide down your nose, press behind your ears, or touch your cheeks when you smile? Those answers tell you more than your age, your head size or any chart.

Choose the SonaVue shape closest to a pair that already sits well on you. Shape is a matter of taste; a secure fit is what makes them comfortable all day.

Three shapes, one size each

All three are designed to be worn by anyone and come in one standard size. If you have a narrow face, try them on before you decide.

• Classic: a classic squared shape in gloss black acrylic.
• Jona: a rounded shape in gloss acetate.
• K-Man: an angular shape in gloss acetate.

Reading the numbers on a frame

Most frames carry three numbers, such as 52□19-145: the width of each lens, the width of the bridge and the length of the temple, all in millimetres.

They are a good starting point, but two frames with the same numbers can still fit differently. Compare how wide the front is and how the bridge sits on your nose.

What an optician can and can't do

Prescription lenses are centred for your eyes, but they don't fix a frame that slides or pinches.

• Can: make small adjustments at the nose and the frame front.
• Can: often fit your own prescription lenses. Check with yours before you order.
• Can't: heat or bend the temples. They hold the speakers, the battery and the electronics.
• Can't: turn a bridge that doesn't suit your nose into one that does.

Signs of a good fit

• They stay level and don't slide when you look down.
• No pressure marks behind your ears after an hour.
• Your lashes and cheeks stay clear of the lenses.
• The speakers sit just above and in front of your ears.
