Your glasses are not just a fashion statement. Your glasses are an extension of your being. So many Canadians rely on modern optometry technology to allow them to live a normal and functioning life. Prescription glasses serve a multitude of purposes, which include driving-specific lens and lenses designed for workers that stare at computer screens all day. The manufacturing process of the eyeglass lens is intense and complex as they require a high degree of precision and efficiency to ensure they accurately assist people in need of proper eye care. Here is the abridged process of how prescription eyeglasses are made:
Preparing the Lens
Production for most prescription eyewear is done through automation, which largely prevents human error from affecting the lens. Once we receive the schematics for the lenses, we can then begin manufacturing the eyeglass lens. To ensure that our customers’ prescriptive needs are fulfilled, each prescription is branded with a unique bar code. The barcode will be used following the production of the prescription lens to ensure the customer receives their glasses.
Lens Are Secured with a Protective Coating
During the early stages of lens production, the lens is fragile, and therefore, a protective coating must be added to ensure that the glass can withstand the manufacturing process. This step is imperative to the finished product because the eyeglass lens will be put through a plethora of different machines and tests and without the protective coating, scratching, denting, and cracking could ruin the glass. When the application of protective coating has been added, we then move on to our next stage.
Once our previous step has been completed, we can then generate the lens so that it is designed to meet the customer’s specific needs. When our lenses are pulled from our warehouse, the front side of the lens is already endowed with the optical capability required to provide our customers with improved vision. The back part of our lens still needs to be produced. To prepare our lenses, we must use a CNC machine that adequately shapes the lens and fulfills the prescription parameters. Essentially, the lens is contorted so they can be given a standard shape. Following this step over 9,000 tiny little machining points are set in place so that optical technicians can add the prescription.
Refining the Lens
Our lens needs to be polished and refined before they can be released to our clients. The polishing process smooths and glosses the lens, which is imperative because a clean surface is needed so that the protective coating is not detached from the lenses.
Lens Are Cleaned
Our prescriptive lenses are carefully removed from our machinery and cleaned with precision tools. We ensure each lens is scrubbed with a utility brush, and we use a variety of chemicals to guarantee the lens is cleaned and prepared for supplemental coating procedures. Great Glasses takes extreme precautions throughout the cleansing process to ensure we are reducing our environmental footprint. Therefore, certain elements, such as metal alloy are repurposed. The water used in the manufacturing process is recycled.
Lens Tint is Added
At this point in the lens production process, depending on the preference of the client, tint is added. Our plastic lenses are descended into a vat of dye. For glass lens, a coating of metal oxide is added to the glass. The coloured dye and metal oxide is completely safe and poses no danger to human health or the environment. Each one of our customers is individualistic and has a unique preference for the level of tint they want to be added. Therefore, the process is performed articulately and requires an intense level of aptitude on behalf of our optical technicians.
Perhaps the most intricate component of the lens production process is the application of the final coating. Coating prepares the plastic lens for the rough and tumble of everyday life. Understandably, things will occur while you are wearing your glasses that may cause scratches or dents to occur on the lens. For example, throwing your glasses into the cubby hole of your car or onto your dresser before you go to bed; unfortunately, scratches and dents are inevitable. When we add another layer of coating to the lens of your glasses, your glasses are provided with extra protection against harsh weather conditions, stains and dirt, and annoying glares from the sun.
Great Glasses takes immense pride in ensuring our lens are suited for our client, and that means going the extra mile to ensure that we did a good enough job creating their lens. Our technicians’ triple checks all the lenses that leaves our warehouse and inspects them for any flaws that could hamper the effectiveness of our glasses. Certain things that we check for are if the lens is the correct thickness for the prescription and if the design is accurate to the preference of the customer. The entire process is time-consuming and intricate, which is why we triple check everything to make sure that we reduce the number of resources we consume, as well as make sure the customers get their glasses on time.
To recap, the process in which we make a lens for your glasses is complex and elaborate. We want your glasses to be more than just a pair of glasses to you, and we want them to become a reliable and aesthetically pleasing device that improves the quality of your life. All our lenses are manufactured with the utmost care and consideration for your vision and physical appearance. You treat your glasses with care, so it is only fair they are made with the same amount of care.
