Synergy 6048

Synergy 6048 Prescription Glasses

Square frames have a confident, modern look that works almost anywhere. The Synergy 6048 is a unisex full-rim plastic square frame, sized 53-18-145, in Crystal or Havana. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Synergy range.

Choosing your Synergy 6048 colour

Crystal. The Crystal version is crystal clear. It keeps the look soft and understated, and it works especially well on fair skin.

Havana. Havana is a warm tortoiseshell. It is softer than black and suits brown, auburn and red hair.

If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.

Shape and style

Square lenses add structure to round and oval faces and make features look more defined. The crystal finish is clear and fresh, and it lets your features take centre stage.

Small metal studs at the corners add a neat, vintage finishing touch. The thicker frame front gives it real presence on the face. Plastic keeps the weight down and allows richer, deeper colour than metal.

Whether it is your main pair or a spare, the Synergy 6048 is easy to live with.

Styling tips

It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.

Size and fit

At 53mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 124mm.

Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.

Lens options for the Synergy 6048

Your optometrist’s prescription will usually tell you which of these you need:

• Single vision: one prescription for distance, reading or the computer.
• Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
• Bifocal: a defined reading area at the bottom of the lens.
• Ready readers: simple magnification for close work.

At 42mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots of room. If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night. Spend a lot of time on screens? This frame is also part of our blue light glasses range.

Ordering online is easier than you think

All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.

From our lab to you

Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Synergy 6048 and then sends your glasses to you in Australia.

Keep them looking new

Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
