5 Visual Functions for Optimal, Natural Vision
Our natural vision is achieved through 5 visual functions, to put it simply. The requirements for Optimal, Natural Vision after lens exchange are met, as long as all 5 functions are operative. Click on the graphic below and see which effects the visual functions have on your vision. (Disclaimer: Visualization is for demonstration purposes only. Individual results may vary.)
Distant function
The distant function is responsible for sharp distance vision, e.g. when looking at the London Skyline.
Near function
The near function of the natural lens ensures sharp vision by accommodation at close range (up to 40 cm). When looking from the skyline to the cell phone, the lens changes its shape and creates a sharp image on the retina according to the distance to the viewing object.
Intermediate function
The intermediate function of the natural lens allows sharp vision even in the middle distance range (up to 1 m). The lens is elastic and adjusts its curvature according to the distance, e.g. the lantern with railing.
Mesopic function
The mesopic function ensures high-contrast vision even in situations of poor light conditions. Due to the special (spherical) shape of the lens you still enjoy adequate vision when there is twilight or fog. This function takes only effect when light conditions are poor.
Imaging function
The imaging function of the cornea ensures distortion-free vision. In the event of a corneal astigmatism, the entire visual perception is distorted, incapacitating the imaging function.
