Past efforts to reduce swim effect in progressive lenses has focused mainly on the reduction and precise placement of unwanted cylinder error in the periphery 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 Technology
Steady Technology allows for strict control of the lens power resulting in a progressive lens with unparalleled wearer satisfaction.
Superior image stability for more comfortable vision
Inspired by stability
‘Swim effect’ is the perception of your surroundings that causes discomfort, and reduces overall wearer satisfaction and making adaptation more difficult.
Despite advancements made in progressive lenses, patients still experience swim effect. But, lenses designed with Steady Technology provide you with a more stable, natural image.
Benefits
Higher image stability for reduced swim effect.
Improves peripheral visual acuity in the distance.
Steady carefully controls the mean power (spherical equivalent) of progressive lenses and dramatically reduces unnecessary swim effect.

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.
