Bifocus

 

Of new dimensions for bifocal glasses

 

 

AtLast! A revolutionary multifocal lens which offers ten times better vision, thanks to the integration of a triple progress in the near zone of vision.

 

AtLast! The quadrifocal lens

 

Neither bifocal, nor trifocal, atLast! A multifocal glass with vast fields of vision with 4 zones of vision (Quadrifocal). He exploits the properties of a revolutionary composite, constituted by organic material 1.67 and Trivex 1.53, to offer an exceptional optical quality and a maximal resistance.

 

The glass is available

 

  • · atLast! Composite 67 and

  • · atLast! Composite 67 Transitions brown / grey

 

For several years, the industry concentrates its efforts of development on multifocal lenses.

But certain farsighted always appreciate the characteristics of the bifocal glasses, such as the absence of peripheral deformations, the fast adaptation and the easy localization of the various zones of vision.

The multifocal glasses at Last! Represent more than 15 years of development intended to meet the needs of these persons!

 

Conventional bifocal glass atLast! The multifocal glass with vast fields of vision

 

              

 

Propose a better visual performance to the bifocal and trifocals wearers.

 

The bifocal glasses contain only two zones of vision, for near and far. Trifocals glasses have

an additional intermediate zone.  AtLast! Possess four zones of vision: near, near extended

, intermediate and distant vision. So, this glass offers a vast range of vision, practically without

Transitions, with smooth transition from near to infinity.

 

AtLast! - 4 zones of vision

 

An intermediate zone for which the customers waited for a long time! The segment integrated the reading zone with a triple correction, which covers all the zones of vision between near vision and the intermediate vision zone.  

The vision between readings to distant vision is almost made without transitions.

 

  • · Four zones of vision: near, near extended, intermediate and distant vision

  • · passing from near to intermediate vision at 1.5 m practically without transitions

  • · Soft transition during passing from distant vision to the intermediate zone

  • · Optimal distant vision with a wide field of vision

  • · Near segment almost invisible; without image jump

 

An improved aesthetics

 

AtLast! Uses two materials, the ORGA 1.67 and the Trivex 1.53, thanks to a revolutionary technology. A patented process allows fusing materials in the molecular scale it results from, to give a more general-purpose and more long-lasting glass, endowed with excellent optical qualities, allied to a maximal structural integrity.

 

atLast! advantages

 

  • · Zone of vision closely almost invisible.

  • · Zone of additional vision in the intermediate zone.

  • · Jump of image sharply less marked than with glasses bi-and trifocals, passing from distant vision in the intermediate zone.

  • · Fluid Transition between near vision and the intermediate zone.

  • · Aesthetic, fine and light Glasses.

  • · Extremely resistant Glasses.

  • · Absence of laterals deformations.

  • · Fast Adaptation.
