Is a new vertical aspheric lens conceived by HOYA  to relieve the eye and  to give a smooth vision at all distance and give a comfortable vision all day long.

For eyes which work all day long
All the time our eyes are very solicited to focus at all distances. We must remain at the same time concentrated for near visioin (computer. pounds, GPS. phones) while remaining attentive to an environment continuously in movement.

The Active solution
Hoya gives you a tremendous opportunity to bring a concrete answer to customers demanding a glass adapted to their style of life.  

• Nulux Active is an unifocal giving a smooth correction in the lower part of the lens. It is ideal for the wearer who needs a better correction then a normal unifocal.  
• Nulux Active is an alternative solution for the wearer who need more competitive glasses to see and at the mid-distance and at near.

Throughout the day, the lens Nulux Active allows the eye to work in the best conditions while relieving it from too intense efforts in order to keep all its energy.
This lens supports the natural activity of the eye and gives a comfortable vision in all directions and at all functional distance.

Easier accommodation

A technology of new generation
Thanks to an asymmetrical conception and the aspheric front surface, the lens generates retinal overlapping images. You have the guarantee of a slack binocular vision whatever the gaze direction, a perception of constant picture and comfortable vision at all distance. The wearer can easily sustain a visual attention (job, reading, computer)

An adapted solution
Active Nulux is declined in two levels of correction: the first with 0.53 D is adapted to for patient of  20 years of age, while the second, with 0.88 D targets the young longsighted persons. Even the contact lens wearer will benefit from the visual performances and the comfort thanks to Nutux Active, especially in their activities in near vision.

"ANTI-EYESTRAIN" LENSES FROM  ESSILOR

Essilor recently launched on the French market a new lens "Essilor Anti-Fatigue", This uni-focal is given for objective to answer, to the 60 % of people waiting,  from 20 to 45 years which complain about visual strain (asthénopia.) a visual strain which appears to 54 % by a feeling of "eyestrain ", to 52 % by "headaches", and 47 % by problems of adaptation to the light.
This eyestrain appears during close work (70 %), work on screen (71%), but it is felt to 84 % as a "global fatigues". On the technical level, the design of "Essilor Anti fatigue" is based on the regulation of the micro fluctuations of accommodation.

When the eye fixes a motionless target, accommodation is not constant: it varies around an average position. These variations are called micro fluctuations of accommodation, a universal phenomenon at less than 45 years of age ". (fig. I)

In prolonged  near vision  , these "micro fluctuations" are disturbed. The accommodative system, have more and more difficulties to support this effort. The lens wearer suffers from visual strain. (Fig, 2)

The design of "anti-fatigue lenses" rebalances the accommodative system and recreates these "micro fluctuations" of accommodation. the lens relieves visual strain. (Fig.3)

The lens was then designed, in order to reduce accommodation of 0,6D for the near  vision. Thanks to this specific optimization, this glass then makes it possible to reduce "visual strain" by relieving the accommodative effort necessary for a work supported in near vision .
This patented glass is proposed in  Stylis material with anti-reflection coating (Crystal or Trio) from +1.0 to + 6  cyl 4. Diameters: 60, 65, 70, 75.

*Study carried out with 7324 people age from 20 to 25 years of age  people, waerer or non wearer, fron  March to November 2004 in France, in the United States, in Germany, in Italy, in Brazil, in Australia, in China, in Korea, in India and in Japan
