AI Desk is an advanced occupational lens developed for clear, comfortable vision at near and intermediate distances. Ideal for computer use, reading and other close tasks, its low levels of unwanted astigmatism help minimise the swim effect and peripheral distortion throughout the working day.
The soft, ergonomic design supports quick adaptation, while its optimised power distribution encourages a natural working posture. By helping wearers view their work comfortably without unnecessary head or neck movements, AI Desk can help reduce neck and back strain during office and indoor activities.
Select the working range
The working range is determined by the prescription and selected degression. Discuss the customer’s screen distance, reading distance and furthest required clear working distance before ordering. A desk lens is a task-specific solution rather than a replacement for a full-distance varifocal; assess distance and driving requirements separate.
Simple to dispense. Just order the reading RX required and then state the required Degression. Degression availability is as follows; –0.75, -1.00, -1.25, -1.50, -1.75, -2.00, -2.25y.
Thinning options for plus and minus prescriptions
Thickness reduction complements optical design. It is a separate design and manufacturing consideration, rather than a
benefit produced by AI alone. The finished result depends on prescription, material, frame shape, centration and the selected optical area.
Plus prescriptions with SIZE 2.0
Plus lenses are typically thickest at the centre. ProCrea’s SIZE 2.0 uses the supplied frame shape and wearer parameters
to calculate the required optical area and blend the surrounding surface, helping reduce centre thickness in the finished lens. Accurate frame-shape data is essential to this approach.

Minus prescriptions with lenticularisation
Minus lenses are typically thickest at the edge. ProCrea’s lenticularisation preserves a defined optical area, then gradually changes the surface curvature towards the periphery to reduce thickness. The optical area can follow the frame shape or use a circular profile. Its size should be selected with the wearer’s visual needs in mind, as the peripheral surface is modified.
Lenticularisation can also reduce centre thickness in plus lenses. Our team can advise on an appropriate combination of
design, material and thinning for the individual job. Any reduction should be assessed against a comparable prescription, frame and material; a fixed percentage should not be assumed for every order.
