High-Tech Eyeglass Lenses Made in Europe
Nexa lenses are the result of over 30 years of Optomedical Ltd.’s expertise in optics and ophthalmology, developed in partnership with Diagonal Croatia. They offer a perfect blend of professional know-how, cutting-edge technology, and European quality standards.
Produced in Split, Croatia, in the heart of the European Union, Nexa lenses are crafted on fully automated Satisloh lines, ensuring strict quality control at every step.
Nexa lenses are crafted with modern, optimized progressive designs and high-quality functional coatings, providing:
Optimal ergonomics are essential for ensuring visual comfort when viewing objects. Through a test conducted on thousands of users to measure visual behavior, the optimal vertical tilt angle was determined. The ErgoTECH technology uses this data to automatically select the ideal lens channel. The ideal channel, defined with a precision of 0.01 mm, is the channel length that provides the optimal ergonomic position for each user.
Maximum Aesthetics and Lightness. The patented ThinTECH technology allows adjustments to the lens curvature to overcome common manufacturing limitations and achieve a fully optimized lens that perfectly fits the actual frame. Thanks to its unique production process, ThinTECH enables maximum lens thinning while matching the exact frame shape. The result is the thinnest and lightest lens possible.
Pushing the Boundaries in Progressive Lens Design. Aberrations are inherent characteristics of progressive surfaces, experienced by the wearer as blurriness, causing discomfort and dizziness. CleanVIEW technology is designed to reduce unwanted astigmatism to the lowest possible level, providing unmatched visual fields in progressive lenses.
Perfect Stability for Binocular Vision. Balancing minimizes the amount of aberrations from both sides of the lens channel. This unique mathematical algorithm corrects the inherent astigmatic imbalance between the nasal and temporal areas of progressive lenses. Thanks to OptiBALANCE technology, the lenses deliver similar levels of unwanted astigmatism on both sides of the channel.
Precise Optics in Every Direction of Vision. Optimize lenses for the actual wearing position. Enhanced optics, regardless of frame or prescription. This technology calculates and optimizes lenses based on their true position on the wearer. Each lens sits differently in the frame. Designing the lens according to its actual wearing position is essential to avoid aberrations that reduce visual acuity.
Adapting Lenses to the Digital World. Digital devices have changed the way we experience vision. For many years, nearly everyone has been using digital devices, and they are now used by a large portion of the population, not just a small percentage. DigiTECH technology optimizes lenses by adjusting the channel configuration to provide comfortable, sharp vision when using digital devices.

Myopia Control
Lenses with HRS/HAL (Highly Aspherical Lenselets) technology are specially designed to control childhood myopia, providing both correction and therapeutic effect. Their surface features 558 mini-lenses that slow the elongation of the eye’s axial length—the primary cause of myopia progression.
Myopia Control
Lenses with HRC/DIMS (Defocus Incorporated Multiple Segments) technology are designed to control and slow progressive myopia in children, providing clear central vision and a therapeutic peripheral effect. Their surface features 786 micro-segments that create controlled defocus and slow the elongation of the eye’s axial length—the main cause of increasing diopters.
Myopia Control
MyoBalance lenses are specially designed to control myopia progression, providing not only vision correction but also targeting the underlying cause of increasing diopters. They work through peripheral defocus, sending a signal to the eye to slow its elongation—the main mechanism behind progressive myopia.
The lenses are available in indices 1.50, 1.60, 1.67, and 1.74, with each higher index offering a thinner, lighter, and more aesthetically pleasing lens without compromising optical clarity. Thanks to the progressive design, the material provides high visual clarity, a stable image, and durability for everyday wear.
