Steady Methodology allows for the strict control of mean power resulting in progressive lenses with unparalleled levels of wearer satistaction.
Features
Strict control of mean power in distance area of the lens
Significantly reduces mean power error.
Benefits
- Higher image stability for reduced swim effect.
- Improves peripheral visual acuity in the distance.
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.
Superior image stability for more comfortable vision
IOT has developed new design tools with advanced mathematics that allow for the addition of Steady Methodology into every general-use IOT progressive design.
IOT’s patented Steady Methodology is a technological breakthrough in free-form, digital lenses. In addition to controlling for unwanted cylinder power, Steady Methodology addresses unwanted changes to mean power in the lateral areas of the lens.
This will enable IOT to provide superior progressive lenses for all lifestyles and market segments. Endless Steady Progressive and Essential Steady Progressive lenses now include 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.

Proven results
EXCELLENT DISTANCE VISION*
IMPROVED VISUAL COMFORT*
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.
* Scores of 4 and 5 on a scale of 0 to 5.
Other technologies
Camber Technology
By combining complex curvatures on both lens surfaces, this technology provides excellent vision correction. It is specially designed to increase reading zones and improve peripheral vision.
IOT Digital Ray-Path 2
Oblique aberrations are minimized more effectively than ever by incorporating the intelligent use of wearers’ accommodation into traditional calculations.
Steady Plus Methodology
Steady Plus allows for more sophisticated control of the medium power distribution to improve performance for midrange and near vision. to achieve a perfectly symmetrical and smooth power distribution.
