Optimum vision with
Wetzlich single-vision lenses
What are single-vision lenses?
Single-vision lenses are defined as lenses with a single effect (correction of simple ametropia and astigmatism). The following types of ametropia can be corrected with single-vision lenses:
Astigmatism is a deformation of the cornea. In contrast to myopia and hyperopia, the length or shortness of the eyeball is not relevant here. The curvature of the cornea is not uniform, but has a dent in it. As a result, the light cannot be refracted properly and does not meet on the retina to form a point, but rather a rod shape. “Astigmatism” is derived from the words “A” for “not” and “stigma” for “point”. The translation would then be: “not at one point”.
Quality lenses – a difference you can see
In addition to distortions towards the edges, spherical lenses have a significantly higher inherent magnification or, in the case of minus lenses, reduction in size. You can reduce these defects with modern aspheric or multi-aspheric glasses.

How do you achieve optimal vision at every single point of the lens? Non-optimised lenses have restrictions for the wearer on the periphery, i.e. on the outer edge of the lens. In addition, the image deteriorates as soon as you look through a lens at an angle, because conventional lenses are not optimised for the wearer at every point.
Digital Ray-Path technology simulates how our gaze moves on the basis of the frame shape and individual parameters and adapts every point of the lens to the wearing situation.

Single-vision lenses with near vision support
As a result of the complete integration of mobile devices (smartphones, tablets) into everyday life, a perfect view of your surroundings is becoming more and more important. Since human beings are naturally designed to see better at a distance than at close range, consideration, should be given at an early stage to near vision support in the lens. Single-vision lenses with close-up support are also aimed at the target group of 30 to 45-year-olds. A majority of this target group works several hours a day at a PC and suffers from eye fatigue. In addition, they must deal with various strains that did not exist in the past, such as reading long texts on a smartphone.
