Endless Steady Progressive - Personalized free-form progressive lens with an advanced design. Provides impeccable visual quality. One of the main advantages of free-form technology is it allows for the complete customization of lenses for each wearer. There are many personalized lenses on the market. They all seek to improve visual quality through customization. Endless Steady Progressive lenses are different. Endless Steady Progressive lenses revolutionize the current concept of personalization to incorporating IOT Digital Ray-Path 2 Technology. Endless Steady Progressive lenses are more sophisticated and effective than a traditional personalized lens because the optimization process also considers the wearer’s accommodative ability to focus at different distances. Endless Steady Progressive lenses also incorporate Steady Methodology to drastically reduce swim effect caused by lateral image distortion. A free-form progressive lens that adapts to every lifestyle. Wide viewing range at any distance.

Essential Steady Progressive - Free-form progressive lens. High wearer satisfaction in an entry level technology. A great product portfolio meets all market needs and helps create differentiation. IOT offers a non-personalized lens that is entirely different than any other in its market segment. Essential Steady Progressive lenses incorporate Steady Methodology to enhance image stability and reduce swim effect. Alternative design configurations are available for specific visual needs or lifestyles.

Endless Office Occupational - Personalized free-form lens for maximum performance in intermediate and near zones. With the emergence of remote work, more and more presbyopic professionals (i.e. teachers, programmers, architects) spend a large part of the day using their intermediate and near vision. As optical professionals, it is our duty to offer them comfortable lenses that meet their visual needs. Single vision lenses correct for one point in the distance, and progressive lenses have limited intermediate viewing areas. Endless Office Occupational lenses adjust to wearers’ needs and offer unmatched near and intermediate vision. These lenses incorporate IOT Digital Ray-Path 2 calculation technology, making them fully customizable and reducing oblique aberrations to further expand the wearer´s visual range. An occupational lens with a wider near and intermediate vision range. 

Endless Anti-fatigue Single Vision - Personalized anti-fatigue free-form single vision lens with an advanced design. We spend an average of 11 hours per day in front of a screen, and time viewing digital devices is on the rise. The result: eyestrain. Symptoms include blurred vision, dry eyes, headaches, neck and shoulder pain.

This provides a level of customization that is more effective and sophisticated than other personalized free-from lenses.

Endless Drive Progressive - A premium quality progressive lens for day or night driving.
A standard progressive lens may be uncomfortable for driving. Perhaps the visual field is insufficient, or peripheral vision is limited. At night, the lack of light complicates matters, increasing hazards and causing fatigue. In addition, one out of three wearers experience night myopia, considerably reducing their ability to focus on distant objects. Endless Drive Progressive is a unique customized lens. Its power distribution is specifically adapted for driving. Its night vision zone compensates for the difference in refractive error that occurs between day and night. It provides greater visual acuity and reduces eyestrain. By incorporating IOT Digital Ray-Path 2 Technology, the lens optimization process takes into account the wearer’s accommodative ability to focus on different distances. The level of customization is therefore much more sophisticated and effective than previous methods. 97% of wearers who have used Endless Drive Progressive lenses have felt much more comfortable driving both during the day and at night. Endless Drive Progressive lenses can be recommended for general use.

Endless Pilot Progressive - is a personalized free-form progressive lens with a unique and innovative design that incorporates two zones for near vision. Progressive lenses are designed to have the upper part of the lens focus on distant objects and the lower part focus on near objects. When a wearer has a need to focus on near objects through the upper part of the lens, this configuration is not sufficient. The design architecture of Endless Pilot Progressive lenses is unique. In addition to a standard progressive configuration, it offers an extra segment for near vision at the top. They include IOT Digital Ray-Path 2 Technology which incorporates the intelligent use of the wearer’s accommodation into the traditional calculations for reducing oblique aberrations, resulting in a superior personalized lens. Oblique aberrations are minimized more effectively than ever before.  for near vision. These lenses incorporate a lower vertical power progression with an upper addition segment. This creates areas for near vision at the top and bottom of the lens. Near vision in the upper and lower areas of the lens.

For sunglass lenses and outdoor sports, a wearer’s top priority is to obtain clear vision at all times with the broadest possible range for distance vision. Endless Sport Progressives offer virtually panoramic vision. No other general progressive lenses from IOT have ever achieved such a wide visual field. IOT Digital Ray-Path 2 calculation technology ensures maximum visual performance regardless of prescription, and the selected frame. Focus is always precise and comfortable, even with very wrapped frames. For active people who want impeccable distance vision. Distance fields adapted to active lifestyles. These lenses allow wearers to have virtually panoramic distance vision. Thanks to its unique configuration, the astigmatism lobes are moved away from the primary gaze position. The wearer enjoys a clear 180° field of view. Their architecture maintains an effective field of vision for viewing near objects providing optimal visual comfort at all times. When the patient needs prescription lenses for wrapped sunglasses or sport frames, it is essential that the final lenses are optimized based on the frame parameters to correctly compensate for oblique aberrations. Endless Sport Progressive lenses incorporate advanced IOT Digital Ray-Path 2 calculation technology to virtually eliminate oblique aberrations. This provides patients with clear vision in all useful areas of the lens, regardless of the curvature of their chosen frame.
