Essential Steady Progressive Technologies

Steady Methodology

This methodology, patented by IOT, is a technological breakthrough in digital lenses. It provides a strict control of average power in the far distance vision zone and virtually eliminates peripheral spherical power error.

Improvement of visual range according to the wearer’s lifestyle

A wearer may prefer one progressive lens over another based on their expectations and visual demands. IOT’s general-purpose progressive lenses can be configured for patients’ lifestyles. This provides a more suitable lens design, and greater wearer satisfaction.

The design features an initial configuration where the distance, near, and intermediate fields are balanced. This configuration makes the product more versatile and adapts to most wearers. It´s the most popular and easiest to prescribe.

Three additional configurations are available for patients with specific lifestyle needs.

Essential Steady Progressive Benefits

Higher image stability for reduced swim effect.
Improvement of peripheral visual acuity in the distance zone.
