Multifocal Lenses Brevis®

The growing number of people over forty in the population is also leading to a constant increase in the size of the target group for progressive lenses. The growth in demand for progressive lenses made of plastic materials is particularly strong. At the same time, wearers of these lenses are becoming increasingly fashion-conscious. This means that when they are selecting a frame for their new lenses, a growing proportion of younger presbyopes are opting for small, fashionable models.

The idea behind it all: progressive lens design focused on small frames

Gradal® Brevis is now available as an alternative to the individualised progressive lens Gradal® Short I from Carl Zeiss. Gradal Brevis is the standard progressive lens for small frames. The lens design offers the following outstanding features:

• moderately soft design
• good usability of the distance zone
• short progression zone
• very wide near zone for comfortable reading

And, of course, Gradal® Brevis offers all the proven and excellent features of progressive lenses by Carl Zeiss:

• horizontal symmetry
• aspheric surface design
• variable inset dependent on distance power and addition
• true to prescription
  

Gradal® Brevis - The Benefits at a Glance

• Benefits for the wearer
• Suitable for small, fashionable frames.
• Excellent quality at a reasonable price
• Good usability of the ranges of vision despite the shorter progression
• Horizontal symmetry for optimum binocular vision
• Aspheric progressive surface for low front curvature and good visual quality
• Variable inset for large field of near vision
  

Due to the short progression zone of 12 mm, the recommended minimum fitting height lies at only 17 mm.


Lens stamp and permanent engraving of Gradal® Brevis



Gradal(r) Brevis is fitted in the usual way: position the centration crosses on the pupil centres, with the patient looking straight ahead (distance PD) and his or her head and body in a natural posture.
For easy recognition, a "B" is visible under the nasal "Z" engraving of Gradal(r) Brevis. This is followed by the code for the refractive index, here 50 which stands for n =1.50. The figure engraved under the temporal "Z" symbol indicates the addition which corresponds to the value measured in refraction and hence to the value ordered.
