IOT's Steady Technology Receives a U.S. Patent


TORRANCE, Calif.—Ophthalmic lens design company IOT has been issued a U.S. patent for Steady Methodology, a proprietary technology for creating progressive lenses with reduced peripheral mean sphere power. It is only available on IOT’s Camber Steady lenses. “Steady Methodology is a real breakthrough in free form progressive lens design,” said Daniel Crespo, CEO and president of IOT. “Wearers of this technology often report a ‘wow’ effect. They really can see a difference. The Camber Steady lens combines a digital freeform backside design that includes Steady Methodology with a special Camber lens blank, created in conjunction with Younger Optics.

The result is an incredibly advanced dual surface lens that is truly different than anything else on the market. Camber Steady is one of the best general use progressive lenses ever developed by IOT.”

Steady Methodology addresses unwanted changes in sphere power in the lateral portions of the lens in addition to unwanted cylinder error. Power maps demonstrate how Steady Methodology virtually eliminates positive mean power, which is associated with defocus, in the lateral portion of the lens, according to IOT. In wearer trials conducted by IOT, the introduction of Steady Methodology resulted in an observed 14 percent increase in the width of the distance visual field. Camber Steady lenses also have a lower level and smooth distribution of unwanted cylinder error. This, along with the reduced mean sphere, reduces swim effect, which is associated with the perception of movement. The result is a lens with superior image stability for the wearer, IOT said.

IOT is an independent company headquartered in Madrid, Spain with U.S. offices in Torrance, Calif. It provides differentiated optical technologies, specifically freeform lens designs, including inMotion and Camber Steady, and Neochromes Dynamic light-activated lenses.
