IOT BASIC for the Design of Progressive Lenses

The full name of IoT is Individual Office Technology, or more broadly understood as Individual Object Technology.

Core concept: "Personalized optimization for wearers, not just customized prescription prescription prescription

Simply put, traditional lens production is "prescription driven": you provide the degree (spherical lens, cylindrical lens, axial position), and the factory grinds the lens according to this data.

The design of IoT is driven by "demand and visual ecology": it not only considers your degree, but also comprehensively considers your wearing parameters (such as distance between the glasses, forward tilt angle, face curvature), eye habits, and even the shape and size of the frame. Through complex algorithms, it re optimizes and calculates the optical surface of the entire Progressive Lens for you and the frame you choose, providing a wider, more natural, and easier to adapt field of view.

Comparison with "Traditional Design" (or "Inventory Design")

To better understand IOT Basic, let's first look at how traditional Progressive Lenses are produced:

1.Traditional/Inventory Progressive Lens Design:

Lens manufacturers pre design various "progressive channel" templates (short channel, long channel, hard design, soft design, etc.). These templates are fixed, standard surfaces.

When the optometrist selects a certain lens for you, all the factory does is "map" your prescription prescription prescription to this pre-existing standard surface.

Disadvantage: The standard template is designed for "average face shape" and "average wearing position". If your face shape, frame selection, or wearing habits deviate from the "standard", the visual quality will be compromised, the adaptation period may be longer, and the peripheral astigmatism area may be more obvious.

2.IOT Basic Design:

This is the first step towards fully personalized customization and is currently the mainstream and standard configuration for mid to high end progressive lenses.

After receiving your order, the system does not directly call a complete standard surface. But based on the personalized parameters you provide (including at least monocular pupillary distance, monocular pupil height, mirror eye distance, forward tilt angle, frame size and shape), start from a more basic and malleable "semi-finished blank".

Then, the manufacturing software will use these parameters as input variables to recalculate and optimize the posi                                                                                                             ibution in the surrounding area, to match your frame and wearing condition.

Result: Ensure that the center of the progressive band aligns with the center of rotation of your eyes and maximizes the useful field of view (far, medium, and near) within your frame, while pushing the astigmatism that interferes with vision towards more peripheral areas.   

Key Advantages

● Faster adaptation speed: Because the optical center of the lens aligns better with your visual axis, there are fewer parts of the brain that need to "learn" and "compensate".

● A wider effective field of view: Within the same frame, you can obtain clearer far, medium, and near fields of view.

● Less peripheral interference: Twisted and blurred areas are better controlled and pushed towards the edge.

● Higher wearing comfort: reduces dizziness and shaking sensation, making vision more natural.

● Improve the success rate of fitting: Even if the frame selection is slightly challenging (such as a large frame), IoT design can compensate through algorithms to improve adaptability.

Summary

IOT Basic design is the "smart core" of modern high-quality progressive lenses, including anti fatigue lenses.
