Free-form lens design and manufacturing results in a more precise lens. Free-form progressives allow for wider intermediate and near zones, ease of adaptation and elimination of the peripheral swim found in a standard progressive.   At Intermountain Eye Centers we offer a wide array of advanced progressive lens designs to accommodate all of our patients’ needs. Free-form progressives allow for more lens customization – not a “one size fits all” philosophy.   Hoyalux iD uses revolutionary lens design and technology to give you the comfortable, stable vision you need. The lens is made using the true ‘free-form’ processing. The Balanced View Control principal of Hoyalux iD means that distortions are minimized, vision is stabilized and your sight feels as natural as it did years ago. Hoyalux iD LifeStyle is a semi-personalized progressive design, with the progressive partially shaped on the front and fully customized on the back to provide clearer vision. Summit ECP/Summit CD are progressive lenses that were available prior to free-form technology. The lenses can be used in frames of all sizes and are available in many materials.
