Steady Methodology

Goodrich Optical’s proprietary Steady Methodology is a technological breakthrough in free-form digital lenses.

Steady Methodology allows for the strict control of mean power resulting in progressive lenses with unparalleled levels of wearer satistaction.

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. Endless Steady Progressive and Essential Steady Progressive lenses now include Steady Methodology.

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.

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.

Endless Steady Progressive.
Essential Steady Progressive.

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.
