Natural Posture is an innovative ergonomic design technology enabling the development of lenses that optimally accommodate eyeglass wearers’ head posture when reading or focusing on nearby objects.
Natural Posture technology dynamically locates the near viewing zone within the progressive lens corridor, taking into account the positive or negative power of the prescription. This minimizes the need to tilt one’s head forward or back or raise and lower a book in an attempt to bring the text into focus. Any postural discomfort while reading is thereby minimized, ensuring the patient enjoys a natural, comfortable posture.
The technology enables Shamir developers to dynamically position near viewing zones on lens corridors to optimize vertical head and eye motion and ensure maximum viewing comfort in these zones.
The technology positions the near vision zone higher for minus RX and lower in plus ones, improving the binocular prismatic disbalance for anisometropic cases, ensuring a natural viewing experience.
