FUTURO PRODUCT

SPECIFICATIONS

Futuro Freeform lenses are designed with Free-form Designer™.

Designed in Spain and manufactured under license in South Africa by Basic Optical Laboratories. [email protected] www.basicoptical.co.za

The Futuro-range consists of a comprehensive range of vision correction options, with the option to customise lenses to suit individual – and unique - patient requirements. All Futuro lenses are optimisable, offering Rx compensation for changing vertex distances as the eye moves away from the optical centre of the lens. Lens performance may be further enhanced by utilisation of the full potential of Free-form Designer™ - the Futuro design-tool: individualise lenses according to individual patient requirements and vertex distance, frame dimensions, patient pupil distance, panoramic & pantoscopic angles.

1. INTRODUCTION: SUMMARY OF FUTURO PRODUCT RANGE



The Futuro-range consists of a comprehensive range of vision correction options, with the option to customise lenses to suit individual – and unique - patient requirements.

2. OPTIMISATION:

Digital Ray-Path Technology provides the best optical quality in each part of the lens— these lenses consider the interaction

between the lens and the eye, taking into account lens position & eye movement.

This simple technique drastically impacts the optical quality of lenses. In case of a conventional lens—including freeform

lenses with conventional designs—dynamics of the eye and lens position remain static, resulting in the same design for all

patients, which renders the final wearer experience less than optimum; this decreased optical quality manifests in a smaller

near vision zone and compromised vision in the peripherals of the distance vision zone.

Digital Ray-Path calculation guarantees a first class power optimisation that considers the complete eye-lens system to

provide wearers with an accurate power in any gaze-direction. Oblique astigmatism is totally compensated for - no matter the

power or type of frame.

The picture on the the left il lustrates astigmatic lobes experienced by the wearer of a lens designed with Digital Ray-Path,

while the one on the right illustrates the same lens power in

conventional format. Optimised lenses are made possible with

Digital Ray-Path Technology, resulting in lenses with:

larger optimal vision zones

less unwanted astigmatism.

Lenses not manufactured with Digital Ray-Path Technology—i.e.

conventional designs and not optimised, are referred to as

surface power lenses.

Measuring lens power with a vertometer—conventional lenses have been developed to yield the

correct power when measured l ike this. This type of calculation is known as nominal power

calculation. It assumes that the same design is good for every prescription, i.e. a static design.

But, the eye’s optical system is very different from the optical system used to measure lens

power. The eye rotates around its centre, and the light follows an oblique trajectory that

affects the power experienced by the wearer. The resultant effect is illustrated in the second

diagram. This example shows the power experienced by the wearer of a conventional SV lens

when looking through various areas of the lens.

The difference in power than that actually

prescribed can be more than 0.50D for

lateral gaze of 30° — known as oblique

aberration, the main optical aberration that

cannot be resolved by conventional

surfacing techniques.

The last diagram illustrates the effect of a

lens with the same prescription optimised

with Digital Ray-Path Technology and

surfaced with freeform equipment. The

power experienced by the wearer is stable

throughout the lens, providing perfect

vision for every direction of gaze.

Note that optimised Rx-lenses would have

two lens powers printed on invoices: the

ordered power and the manufactured power,

i.e. the optimised power—the latter needs

to be verified.

C U S T O M I S A T I O N

(SIGNATURE CORRECTIONS) The ultimate utilisation of Digital Ray-Path

Technology is achieved with customised Rx-

lenses.

For optimised lenses the following input data

is required:

Monocular pd’s

Fitting heights

Frame dimensions (box measurements)

For customisation additional information is

required:

Vertex distance

Frame front angle/panoramic angle

Pantoscopic angle/tilt



The Futuro-S single vision lens offers various design options to suit the specific visual requirements of individual patients,

thus providing the practitioner with a wide range of dispensing options.

A single vision lens is just another single vision lens, one might think… providing lenses with the best possible optical performance is our goal, is

it not? Then why choose the lenses at the top (traditional design) if you can have the lenses with obviously fewer distortions at the bottom

(optimised design)?

Design options in the Futuro-S range:

Futuro Optima: optomised single vision for improved optical performance over a larger area of the lens

Acomo anti-fatigue optomised single vision lens incorporating add power into a single vision lens

distance power: 80% of lens surface for distance vision—progression length inadequate for prolonged intermediate

use

3. FUTURO-S SINGLE VISION



Visual fatigue affects the majority of individuals, whether their eyesight is corrected or not. Whether we like it or not, our

lifestyle & activities increasingly require prolonged use of intermediate and/or near vision, for example reading, PC work,

etc.

The scope of dispensing is increased with advanced solutions for specific needs such as these, and answering to the special requirements of the

modern lifestyle is the new Futuro Acomo anti-fatigue, designed for:

● patients between 20 years and presbyopic age;

● patients performing close work for long periods and

● patients suffering from visual fatigue, whether they wear prescription lenses or not.

The lens provides much greater comfort than a standard single-vision correction, as the patient’s natural accommodation pattern is retained.

Eighty percent of the lens surface is for distance vision, i.e. a very rapid transition to the addition power

4. FUTURO-S ACOMOAnti-fatigue



The lens that every office-bound presbyope should have…the reduced amount of difference between the distance and near

vision zones of the lens results in the zones to be wider than those of progressive lenses. The change in power over a given

corridor distance is also not as pronounced.

Progressive and bifocal lens users lift their head 20° when they are working on computers, because they use the middle & bottom of their lens

areas to see what they are doing, resulting in strained neck & shoulder muscles. It is clear from the diagrams below that the selection of an

appropriate design would be determined by a patient’s visual requirements in the work environment. The purpose & design of the Office lens is

not to provide distance vision. However, the selection of dynamic power could result in the power in the upper part of the lens to be similar to

the patient’s distance Rx. The Futuro Office offers seven dynamic/degression powers available - the powers by which the lens power in the near

zone gradually reduces up to a point on pupil height: 0.75. 1.00, 1.25, 1.50, 1.75, 2.00 & 2.25D. The higher the dynamic power, the longer the

reach/depth of field, but this is achieved at the expense of corridor width. It needs to be remembered that the Futuro Office had been

designed primarily for prolonged work at near & intermediate viewing distances.
