Why we choose High Refractive Index Lens?
Thin and Light
Lenses generally become thicker and heavier as optical power increases. But with the development of high R.I. lens materials, it's now possible to make thinner, lighter lenses.
Now, even high-power lenses can be made thin and comfortable to wear.
Safe and Resistant to Breakage
The toughness of thiourethane resin makes it possible to build thin eyeglass lenses with high impact resistance. Thiourethane lenses resist breaking and chipping, even for two-point or rimless glasses, making them safer to wear and use. Thiourethane lenses also exhibit superior workability, which means they can be formed into virtually any design.
Lasting Appeal
Thiourethane lenses feature high wear resistance and resist discoloring over time.
They also allow stronger adhesion of the coating material to the surface. The coatings are more resistant to peeling, even after extended use.
Clear Views
Due to the prism effect, which disperses light passing through a lens, color fringing (chromatic aberration) typically becomes more evident in the view as the optical power of a lens increases.
Lens materials with high Abbe numbers,* like MR-8™, can minimize chromatic aberration.
Refractive Index
Lens materials are classified on their refractive index. This refractive index is the ratio of the speed of light when it travels through air to the speed of light when it passes through the lens material. It is an indication of how much light is bent as it travels through the lens. Light is refracted, or bent, at the front surface of the lens, then again as it exits the lens.A denser material bends light more, so not as much material is needed to achieve the same refractive effect as a less dense material. Hence the lens can be made thinner, and also lighter.
With regular eyeglasses lenses, the center of the glasses is thinner and the outer edges are thicker to facilitate refraction which is what makes prescription glasses work! High index lenses have a higher index of refraction than regular lenses, which means they don’t need to be as thick around the edges to be effective.
High-index lenses mean that the lens itself can be both thinner and lighter. This allows your glasses to be as fashionable and comfortable as possible. High-index lenses are particularly beneficial if you have a strong eyeglass prescription for nearsightedness, farsightedness, or astigmatism. However, even those with a low eyeglass prescription can benefit from high index lenses.
