Natural Posture

Whether working in the office or at home, or maybe just enjoying a good book, reading can be a challenge for spectacle lens wearers. Knowing where to hold the material and how to position the head can be an ongoing problem.

Fortunately, however, Shamir’s Natural Posture technology has been developed as a highly effective, advanced solution.

This innovative ergonomic design technology enables Shamir to deliver lens designs that provide wearers with the most comfortable viewing postures possible. Shamir’s Natural Posture technology has, in fact, enabled the development of lenses that optimally accommodate eyeglass wearers’ head posture when reading or focusing on nearby objects.

Tip: Natural Posture’s ergonomic design lessens the need to raise or lower items or tilt one’s head up or down.


…For every 20 minutes spent reading, the patient should look at something 20 feet away for 20 seconds.


How does it work?

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.


While ideal for anyone reading, it especially benefits anisometropic eyeglass wearers whose eyes focus unevenly and who require varying accommodative eye support.


The technology positions the near vision zone higher for minus Rx and lower in a plus one, thus improving the binocular prismatic disbalance for anisometropic cases, ensuring a natural viewing experience.


Looking beyond the special needs of anisometropic wearers, what does the postural comfort mean for all wearers?

• It maximizes individual postural comfort when reading and viewing nearby objects.

• It minimizes the need to tilt the head up or down or to raise and lower the material.


Eye strain is a big issue for anyone reading for any period of time.

In addition to technology like Shamir’s Natural Posture that enhances viewing comfort, don’t forget to share other tips with patients.

One of the easiest for them to remember is the 20/20/20 rule that you are hopefully already sharing with consumers who sit in front of computer screens for long periods of time. That is, for every 20 minutes spent reading, the patient should look at something 20 feet away for 20 seconds.
