Lenses are the most important part of a pair of glasses, which can greatly ensure that you enjoy excellent vision. But first of all, there is a series of processes before installing the lens onto the frame.

Undoubtedly, the production of lenses starts with seeing an optometrist. The optometrist will perform prescription measurements and create a unique visual profile. Afterward, a suitable lens will be selected and measured to determine how to fix the lens on your desired frame. These are all important factors and data must be passed on to lens manufacturers so that they can produce personalized and optimized lenses that are suitable for you.

What will happen next? How to produce modern customized lenses through visual analysis? Firstly, we will produce semi-finished lenses. You can choose between two materials, resin (also known as organic glass) and "real" glass (also known as mineral glass). These two materials are the foundation for producing lenses.

There are basically two different processes: regardless of the manufacturer, personalized precision lenses (also known as prescription glasses lenses) are almost all produced using free-form surface technology.

Unlike prescription lenses, 'off-the-shelf inventory lenses are produced during the casting process. There is a difference between these two types of lenses: optometrists usually choose inventory lenses as a simple and cost-effective lens choice, such as reading glasses or when the wearer needs to quickly replace lenses. Unlike prescription lenses, these lenses are produced in bulk rather than individually. Inventory lenses are very suitable for standard vision correction, but cannot provide the same level of performance as personalized precision lenses. In order to produce personalized lenses, optometrists need to create a detailed and comprehensive visual profile for eyewear, which serves as the foundation for lens manufacturing.
