Salud postural y ergonomía: el rol de las Lupas Ergo

Postural health and ergonomics: the role of Ergo Loupes

Ergonomics is not just a matter of comfort; it is essential for the long-term health and well-being of professionals.

May marks the second consecutive year of celebrating ‘Ergonomics Month’ in Víttrea, a time to reflect on the importance of maintaining proper posture during clinical practice.

In this article, we will analyze the impact of good postural hygiene on the ergonomics of clinical professionals and how Víttrea’s Ergo loupes are a tool to facilitate proper working posture.

But first, it is essential to ask ourselves:

Why is ergonomics essential?

  • Prevention of musculoskeletal injuries.
  • Promotion of sustainable long-term clinical practice.
  • Reduction of the risk of pain and injuries.
  • Contribution to the longevity of a professional career.

However, many professionals are not fully informed about the basic principles of ergonomics and how to apply them in their work environment, leading to the adoption of harmful habits that negatively affect their long-term health and well-being.

Harmful habits:

Leaning to one side

Instead of asking patients to adjust their position or moving equipment, some professionals have the habit of leaning to one side. This repetitive or prolonged leaning can create strains on the back, causing discomfort and even injuries.

Inadequate working distance

When the working distance is not optimal, the patient’s chair may be poorly positioned, forcing staff to adopt uncomfortable postures. This situation can result in legs trapped under the chair, forcing the professional to adopt non-ergonomic positions that increase the risk of long-term injuries.

The head is connected to the spine by the atlanto-occipital joint, designed to look up and down. Any additional tilt involves other cervical joints, increasing the risk of musculoskeletal disorders.

Furthermore, the static postures maintained by many healthcare professionals can lead to spinal pathologies. Additionally, postures that exert pressure on the intervertebral discs and prolonged hypomobility increase the risk of injuries.

Ergo Technology

Víttrea’s Ergo loupes, the first fully ergonomic ones in the Spanish market and celebrating their fourth anniversary during ‘Ergonomics Month’, have emerged as an innovative solution to improve posture and reduce muscular tension in healthcare professionals.

These loupes allow clinicians to maintain an upright position, look forward, and view the patient treatment area without having to bend the neck, thus helping prevent musculoskeletal injuries and promote a more sustainable practice.

After years of research and development, Ergo loupes have established themselves as the standard of excellence in ergonomics, offering a unique combination of comfort, optical quality, and durability. Professor Piancino, associate professor in the Department of Surgical Sciences at the Dental School of C.I.R. University of Turin-Italy, has researched the benefits of Víttrea’s Ergo loupes in reducing neuromuscular tension, which is crucial as asymmetric muscle activation can lead to short-term pain and long-term injuries.

In this study, it has been found that Ergo loupes reduce asymmetric muscle activation compared to conventional TTL loupes, helping to maintain a more upright posture and prevent musculoskeletal injuries in healthcare professionals, thus ensuring the longevity of their careers.

Health Benefits

The health benefits of Víttrea’s Ergo loupes go beyond improving posture; they reduce muscle tension and distribute the load on the spine more evenly. This not only increases the physical comfort of the clinician but also enhances their concentration and precision in their work.


Importance of Ergonomics in Clinical Practice

It is essential for healthcare professionals to understand the basic principles of ergonomics and to use tools such as Ergo loupes to enhance their clinical practice.

Considerations When Selecting Loupes

When selecting loupes, it is important to consider factors such as weight, declination angle, and optical quality to ensure maximum comfort and effectiveness.

Benefits of Víttrea’s Ergo Loupes

Víttrea’s Ergo loupes offer a range of magnifications from 3X to 10X, being very lightweight systems even with maximum magnification. With a 65° declination angle, these loupes compensate for head tilt and reduce the strain on the cervical spine during long hours of work.

Different working positions according to the type of loupes.

It is crucial to understand that without loupes, neck inclination can reach 45°, increasing the load on the neck up to 22 kg and causing premature wear of the intervertebral discs. Using Ergo loupes helps maintain an ergonomic posture and prevent injuries.

Promotion of Healthy Postures

It’s also important to understand how different working positions affect neck inclination and the load on the spine. Ergo loupes promote keeping the head in a neutral position, making it easier for professionals to maintain an ergonomic posture during their clinical work.

Key points to maintain a correct working posture.

Furthermore, clinicians are recommended to adopt healthy postural habits, such as taking regular breaks, stretching, and maintaining an upright posture throughout the workday.


Víttrea’s Ergo loupes have stood out as an innovative solution for improving ergonomics in various medical specialties.

Dr. Pedro Hernández, a specialist in hand surgery, shares his experience:

“The Ergo loupes have provided me with many advantages. Previously, I used to use straight loupes that forced me to operate with my neck in an uncomfortable position. This resulted in frequent neck pain, radiculopathy, and even cervicobrachialgia, which was quite bothersome. However, since I started using the Ergo loupes, I have experienced a complete change. These loupes allow me to maintain a straight cervical spine, they are incredibly lightweight, and they do not generate any additional strain. I have noticed a significant decrease in the sensation of fatigue and an improvement in neck pain.”

On his part, Dr. Julio Luna, a specialist in Dentistry and Stomatology, who became the first user in Spain of the innovative Ergo loupes in 2020, ensures that:

“The Ergo loupes changed my concept of working and, above all, my posture because I had been using conventional 2.5x and 3.25x loupes for more than 10 years, experiencing a lot of cervical pain that had become chronic and from which I couldn’t seem to recover. They are highly recommended for any professional who cares about their cervical spine and seeks lightness and comfort.”


In summary, Ergo loupes are changing the game for healthcare professionals by improving posture, reducing muscle tension, and promoting a more sustainable practice.

By adopting ergonomic tools like these, clinicians can enjoy a longer and healthier career while providing the best possible care to their patients.

At Víttrea, we are committed to leading innovation in ergonomics and supporting healthcare professionals in their pursuit of a safer and more comfortable clinical practice. That’s why, during ‘Ergonomics Month’, we invite you to request a free trial of loupes at your clinic, with no obligation and with a special discount.
