Features
Strict control of mean power in distance area of the lens Significantly reduces mean power error.

Steady Methodology
IOT’s proprietary Steady Methodology is a technological
breakthrough in free-form digital lenses.
Steady
Methodology ensures precise control of average power in progressive lenses, leading to exceptionally high wearer satisfaction.
Benefits
Steady Methodology carefully controls the mean power (spherical equivalent) of progressive lenses. Steady Methodology dramatically reduces unnecessary mean power in the periphery, especially on both sides of the fitting cross.
- Higher image stability for reduced swim effect.
- Improves peripheral visual acuity in the distance.
Superior image stability for more comfortable vision
IOT has created new design tools equipped with advanced mathematical capabilities, enabling the integration of Steady Methodology into every general-use IOT progressive design.
IOT’s patented Steady Methodology represents a technological advance in free-form, digital lenses. It not only controls unwanted cylinder power but also tackles undesired variations in mean power in the lens’s lateral areas.
This advancement allows IOT to offer superior progressive lenses suitable for all lifestyles and market segments. Both Remedy Max and Remedy Plus Progressive lenses now incorporate Steady Methodology.
Inspired by stability
Swim effect is a non-stable perception of the surroundings that causes discomfort, and reduces overall lens satisfaction, making adaptation more difficult. Despite advancements made in progressive lenses, patients still experience swim effect. Lenses designed with Steady Methodology provide wearers with more stable and natural vision.
Past efforts to reduce swim effect in progressive lenses have primarily focused on the reduction and precise placement of unwanted cylinder error in the lateral areas of the lens. However, unwanted mean power also plays a significant role in the perception of swim effect, and in overall wearer satisfaction. Mean power error can drastically increase blur and reduce visual acuity.

Results
In a double-blind study:
- Wearers wore the progressive glasses for a week. At no time did they know the type of lens they were wearing.
- All wearers were asked about their user experience and level of satisfaction.
