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.
Steady Plus Methodology
Steady Plus Methodology, only available in Camber Steady Plus Progressive lens designs, is an improvement of Steady Methodology. Steady Plus Methodology allows for more sophisticated control of the mean power distribution to improve performance for intermediate and near vision.
Superior image stability for more comfortable vision
Goodrich Optical’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 Goodrich Optical to provide superior progressive lenses for all lifestyles and market segments. In addition, Camber Steady Plus Progressive lenses now include Steady Plus Methodology, an improvement to Steady Methodology that also provides superior binocular visual performance for mid-range and near vision.
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 Plus Methodology provide progressive lens wearers with more stable and natural vision.
Benefits
Improved visual performance in intermediate and near.
Distribution of spherical equivalent with Steady Methodology and Steady Plus Methodology
Traditional progressive lens
Lens with Steady Methodology
Lens with Steady Plus Methodology
Lenses available with Steady Plus Methodology:
Steady Plus Methodology adds a substantial improvement in the wearer’s binocular performance and provides a smoother visual experience as both eyes perceive identical powers for each gaze direction.
Proven results
Excellent near vision*
Excellent near and intermediate vision*
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.
Features
Strict control of mean power in distance area of the lens
Binocular balance improvement
