HOYALUX GP WIDE

A Progressive With a Wider Perspective

Reading Area Widened With 23%...

Now even closer to natural vision
By introducing the 'Transmission Based Lens Design’ concept in 1996, HOYA took another step closer to achieving natural vision. But in the daily life of today’s consumer, flexibility is an absolute must. Situations change frequently and consequently, the ergonomics of the progressive concept become increasingly important.
HOYALUX WIDE is designed for the presbyope who expects a lot more than standard design offers.

An eye for the detail
When designing the HOYALUX WIDE, careful attention was paid to the reading area, whilst being mindful of compensating for the resulting side effects. Gaining an impressive 23°/% in the reading area, while not affecting the other characteristics of the lens, adds tremendous value to the progressive concept in general. Additionally, close attention was paid to compensating for the increase or decrease in convergence when reading as a consequence of varying powers. Now both eyes can work together and this means better binocuLar vision and depth of vision. However, compensating for variabLe convergence is not enough. In combination with HOYA’s new power distribution, based on ‘Transmission Based Lens Design’, a 23°/% enlarged near vision field is obtained.

 

According to the natural convergence of eyes HOYALUX GP WIDE incorporates a variable 'inset' of the reading part (max 3.4).

 

 

 

 

 

 

  
The ergonomic concept of HOYALUX WIDE enlarges the usable near vision area by a combination of compensating the optical side effects
and a smoothed distribution of peripheral distortion.

 

...Without Affecting Other Correction Areas.

Quality across the entire field of view
Normally, corrections and improvements to one aspect of a progressive design have consequences in other areas. Logically, broadening the reading area implies an increased concentration of distortion in the periphery and in the distant vision area, which affects the quality of the whole field of vision. HOYA succeeded in solving this problem while designing HOYALUX GP WIDE.

Transmission Based Lens Design
HOYA applies a calculation technique, using 3-dimensional computer simulations based on transmission of light and using the eye as a reference. The advantage is that a design can be fine tuned again, in order to improve natural vision. That’s why there are no negative side effects especially for the far vision part, when the reading area is widened. The calculation applied towards the nasal side and the peripheral areas are very accurate, which result in a 23% enlarged near vision field and an excellent perception of natural and spatial vision. For both the plus and minus tens powers, separate asymmetrical and aspherical designs are being manufactured.

 

Better controllable calculation of the progressive zones towards the nasal side and the peripheries result in an ergonomic build-up of the correction areas.

 

 

 

 

 

 

  
The build-up of peripheral areas is ideal so that natural and spatial vision are not at their optimum for every distance.

Progressive in a Wider Perspective

Short effective zone Length of 14 mm.
For those who want to switch easily between visual zones will generally find that vertical head movements interfere with smooth progressions. Thanks to the short progressive zone length of 14 mm., any accommodation deficits are compensated very effectively, without the need for extra head movements.
The vision area is widened by 23°/% in both lower and higher additions, thanks to the transmission based calculation method for each addition. The balanced combination of a short progressive zone, an extra broad reading area, balanced peripheral areas and the compensation of the variable convergence make HOYALUX GP WIDE an optically optimum design, resulting in maximum reading comfort and a natural, spatial vision.
In summary, 123% satisfaction because of:
• comfortable smooth changes among the far vision, intermediate and reading areas;
• optimum freedom of movement in the far vision areas;
• a wide, effective and functional reading area, which minimizes compensating movements of the head;

  
 
The balanced combination of a short progressive zone, an extra broad reading area, balanced peripheral areas and the compensation of the variable convergence make HOYALUX GP WIDE an optically optimum design.

 

 
A success well received

A survey among customers made it clear that HOYALUX WIDE has been well designed to meet the needs of today’s dynamic and demanding spectacle wearer. Those who took part in the trials for HOYALUX GP WIDE, including
new presbyopes, were very enthusiastic about the design and its features.
