I.O.T Digital Ray Path

This patented technology is the revolutionary method developed and based off of the state of the art eye-lens mode. The lenses that are developed from this method can be at any position in regards to the eyes. The model itself allows this for it is a fully binocular model. The lenses can then be adjusted for prism, patoscoptic tilt, wrapping angle, shape contours, and further adjusted to fall at any distance from the eyes. Digital Ray-Path technology is built to handle variable object space. It can manage back and front surfaces of any complexity. The surfaces need to be spherical, torical, or atorical for the technology to work. So, depending on the lens need to optimize, with this method each object is located at a distance that it would naturally be in the real world.

The rays come into the retina from any point of the object space, and then back to the eye. All variables are taken into consideration, including skew rays and finite pupils. To get the final product, image quality is computed by an imaging model that takes into account eye and lens characteristics.

This calculation method sorts through all the variables that have an impact on the final visual quality. This method produces high-quality results that surpass other traditional methods and models. These lenses can be viewed out of any angle while still providing the customer with the image quality and sharpness that they require. These lenses can be completely personalized to suit the wearers’ needs, while also being the very best that optical technology can offer.

Seiko’s Advanced, Dual Patented 100% Internal Free-Form Technology

The benefits of free form technology are a universal design that provides an extra wide reading area, perfect spherical curves that eliminate any distortion, expansion of intermediate and near vision by placing optics near the back, and an advanced aspheric compensation in the immediate and near zones.

What is free-from?

“Free-form” is a term which refers to the manufacturing process that reduces higher-order aberrations in eyeglass lenses. This technology greatly reduces the chance of spherical aberrations that can occur from traditional eyeglass lens manufacturing tools and processes. Free-form lenses allow the use of computer-aided design and surfacing technology to assist in crafting a high end, customized lens with the customers unique prescription and frame.
