Fovea centralis transmitted light design

What is the fovea centralis?

The fovea centralis is a part in the retina with maximum visual acuity and is located slightly closer to the ear from the center of the eyeball. When a person looks at an object, he/she unconsciously tries to look at it through the fovea centralis.

中心窩透過光設計

New design ensuring maximum natural vision

Unique transmitted light optimum design considering the “fovea centralis” where the visual acuity of the retina is the highest. HR is the next-generation back-surface aspheric lens that ensures the maximum natural power of the eye.

本来の見え方を最大限引き出す新設計

The side vision of the lens is also comfortable by the aberration correction of both eyes.

The vision when both eyes look at the side is clear by aberration correction in a simulation of the line of vision of both eyes.
