Occasionally a bubble is not removed during refining, a sand grain refuses to melt, a tremor in the tin puts ripples into the glass ribbon. Automated on-line inspection does two things. It reveals process faults upstream that can be corrected. And it enables computers downstream to steer cutters round flaws. Flaws imply wastage; while customers press constantly for greater perfection. Inspection technology now allows more than 100 million measurements a second to be made across the ribbon, locating flaws the unaided eye would be unable to see. The data drives ‘intelligent’ cutters, further improving product quality to the customer.

The prices for most Sunglass Fix replacement sunglass lenses for I-dealoptics range from as little as $34.99 to about $70.99.

Float glassmanufacturers

At The Sunglass Fix, we understand how important great optics are in your I-dealoptics sunglasses. That's why we've developed precision polyamide lenses with the optical clarity of glass. Our high-quality replacements restore your sunglasses to look and perform as well as the day you bought them.

Coatings that make profound changes in optical properties can be applied by advanced high temperature technology to the cooling ribbon of glass.

There is a short list of countries that we currently cannot ship to for a number of reasons, mostly to do with shipping restrictions imposed on us.

As an award-winning company, we have been making high quality replacement lenses for I-dealoptics sunglasses since 2006. Sunglass Fix replacement lenses and their coatings are simply the best in class.

Float glasscomposition

Don't worry! Our custom lens service can create a pair of lenses for almost any sunglass model on the market, at no extra cost.

Despite the tranquillity with which float glass is formed, considerable stresses are developed in the ribbon as it cools.

The process is not very difficult. However, it’s important that you select your exact and correct sunglass model and lens size on our website.

The Sunglass Fix have made every effort to make your polyamide replacement lenses as durable, strong and lightweight as possible in the market today, at a reasonable price. Look after your lenses and they will last you for years to come.

Our replacement lens polarization is ranked as the best available on the market. The anti-reflective and mirror lens coatings have more effective scratch protection than most lenses on the market.

The Sunglass Fix offer a wide variety of vivid colors in our range of replacement lenses for I-dealoptics sunglasses. From bold mirrors to subtle gradients, all our lenses provide 100% UV protection.

The principle of float glass is unchanged from the 1950s. But the product has changed dramatically: from a single equilibrium thickness of 6.8 mm to a range from sub-millimetre to 25 mm; from a ribbon frequently marred by inclusions, bubbles and striations to almost optical perfection. Float delivers what is known as fire finish, the lustre of new chinaware.

What isfloat glassused for

Float makes glass of near optical quality. Several processes – melting, refining, homogenising – take place simultaneously in the 2,000 tonnes of molten glass in the furnace. They occur in separate zones in a complex glass flow driven by high temperatures. It adds up to a continuous melting process, lasting as long as 50 hours, that delivers glass at 1,100°C, free from inclusions and bubbles, smoothly and continuously to the float bath. The melting process is key to glass quality; and compositions can be modified to change the properties of the finished product.

On-line chemical vapour deposition (CVD) of coatings is the most significant advance in the float process since it was invented. CVD can be used to lay down a variety of coatings, less than a micron thick, to reflect visible and infrared wavelengths, for instance. Multiple coatings can be deposited in the few seconds available as the glass ribbon flows beneath the coaters. Further development of the CVD process may well replace changes in composition as the principal way of varying the optical properties of float glass.

Watch the magic of this science-based process begins to unfold, in a series of stages on a float line that may be nearly half a kilometre long. Raw materials enter at one end. From the other, plates of glass emerge, cut precisely to specification, at rates as high as 6,000 tonnes a week. In between lie six high integrated stages...

Replacing your I-dealoptics lenses can be easily done at home, and in most cases does not require any tools. We provide step by step video instructions to help every step of the way.

All orders ship from our optical lab in Australia using postal services and couriers where applicable. The shipping time depends on the shipping method you selected at checkout, and your shipping country. Most orders will arrive within a few days up to two weeks, but may take much longer. Please see our Shipping Information page for more detail.

When you have found your model on our website or chosen a custom made pair of lenses, you will be able to choose from three premium quality lens types and more than 15 colors. You will be able to see your order price with your selection.

The replacement process depends on your I-dealoptics sunglass frames, which are usually made of plastic, metal, or may even be rimless. If you manage to get your old lenses out of the frames, that’s great, as putting the new ones in is usually easier.

Fine-grained ingredients, closely controlled for quality, are mixed to make batch, which flows as a blanket on to molten glass at 1,500°C in the melter.

All Sunglass Fix replacement lenses are scratch-resistant, oil- and water-repellent and virtually shatter-proof. The lenses undergo industry standard abrasion testing and rank about 40% higher than competitor products that cost four times as much.

Polarized lenses reduce glare and improve clarity. At the Sunglass Fix, we offer high-quality polarized lenses for I-dealoptics sunglasses, using industry-leading Japanese polarization films.

The float process is renowned for making perfectly flat, flaw-free glass. But to ensure the highest quality, inspection takes place at every stage.

Tracking is highly recommended for any destinations outside of Australia. We ship with couriers and postal services as required, all over the world. Please see our shipping page for details per region.

Our custom service can engineer a pair of high quality lenses specifically for your favorite I-dealoptics sunglasses, no matter how old, or rare the model.

Glass from the melter flows gently over a refractory spout on to the mirror-like surface of molten tin, starting at 1,100°C and leaving the float bath as a solid ribbon at 600°C.

We offer a 6-month satisfaction guarantee, so if you order the wrong size or aren't happy with the color, you can exchange or return your lenses for a full refund. We also stand behind the quality of our lenses with a lifetime breakage warranty and a 1-year warranty against manufacturer defects.

Replacing your I-dealoptics lenses is an affordable way to restore your sunglasses without the need to buy a new pair. Sunglass Fix premium replacement lenses deliver high quality at a fraction of the cost of new sunglasses.

Each year, around one billion pairs of sunglasses are made, with many ending up in landfills. By choosing high-quality, affordable replacement lenses you're making a more sustainable choice for both your eyewear and the planet.

Too much stress and the glass will break beneath the cutter. To relieve these stresses, the ribbon undergoes heat-treatment in a long furnace known as a lehr. Temperatures are closely controlled both along and across the ribbon. Pilkington has developed technology which automatically feeds back stress levels in the glass to control the temperatures in the lehr.
