DLS

Digital freeform lenses designed by IOT and made in our St. Cloud lab: three progressive tiers, plus designs for the office, driving, sport and single vision.

A complete digital lens portfolio, designed by IOT

The DLS portfolio is designed and engineered by IOT. It runs from everyday progressives to specialty designs for driving, sport and office work, with good, better and best options for every patient and budget.

Freeform, point by point: Every DLS lens is made with freeform technology, its surface optimized point by point for the patient’s prescription.
Personalized to the wearer: DLS designs account for individual wearing parameters: frame fit, vertex distance and pantoscopic tilt.
Less peripheral blur: Wavefront management reduces the peripheral distortion and swim effect common in conventional progressives.
Easier adaptation: Wider, more natural visual corridors and smaller aberration zones help patients adapt faster.

Good, better, best progressives

Three tiers of digital progressive, so you can match the lens to each patient’s needs and budget.

DLS Camber Steady+
Best
A fully personalized, dual-sided progressive with Camber technology: better binocular performance at near and intermediate, near elimination of peripheral blur, and the widest fields of view in the DLS portfolio.
Ideal for: Patients who want the most the DLS range offers.

Specialty and single vision designs

Beyond everyday progressives, DLS has designs for office work, driving, sport and overhead near work, a digital bifocal for patients who prefer one, and two single vision lenses. At the desk, behind the wheel or on the go, there is a design for how the patient lives and works.

DLS Task Pro+
Occupational
A personalized occupational lens with maximum near and intermediate fields. Comfortable, precise focus on electronic devices, better posture at the desk, smooth dynamic vision between near and intermediate, and near elimination of peripheral blur.
Work styles
Task Pro+ 1.0: 35 cm to 1.3 m (14 in to 4.2 ft), desk-level work with prolonged near use
Task Pro+ 2.0: 35 cm to 2 m (14 in to 6.5 ft), desk work at intermediate and near
Task Pro+ 4.0: 35 cm to 4 m (14 in to 13.1 ft), a room-sized workspace
Min. fitting height
16 or 18 mm
Technologies
Spatial Vision, Eye Focus Profile, Ray Tracing
DLS Drive+
Driving

The technology behind DLS

Eight core technologies. Each lens combines a different set of them; the table above shows which.

Surfaced lenses on a lab tray beside their job ticket

Camber: A patented dual-sided lens with a variable base curve, for wider fields of view, sharper near vision and better aesthetics in plus lenses.
Spatial Vision: Optimizes gaze directions across the lens surface for better spatial and dynamic vision.
Eye Focus Profile: Maximizes the clear viewing area and reduces peripheral blur, based on each wearer’s accommodative ability.
Ray Tracing: Point-by-point optimization calculates the lens surface for precise vision at every distance and direction of gaze.
Binocular Vision: Comfortable, balanced vision even when the left and right prescriptions differ.
Visual Stability: Reduces the swim effect when the wearer moves, for faster adaptation and a more natural visual experience.
Digital surfacing: Flexible designs and variable corridor lengths for clear vision and consistent quality across the range.
Digital Vision: Optimized near and intermediate zones that ease eyestrain from digital devices.

Made in our St. Cloud lab

Every DLS lens is manufactured in our St. Cloud facility with freeform surfacing and coating technology. IOT designs the lens; we surface, coat and finish it for your patient.
