What is a progressive Free-Form, AI or HD lenses?   

Traditional progressive lenses are produced using “pre-molded” templates and the same design is use for every eyewear.

Free-Form, (AI) artificial intelligence, or (HD) high definition are customized lenses based on computer automated design. These lenses are made with high precision tools to create special surfaces on both the front and back surfaces of the lens. These lenses will provide you with clearer vision in every gaze direction and in all lighting conditions, wider range of vision, better optical quality designed around the individual, their frame to reduce distortion.

HD or AI lenses are available in a wide range of single vision and progressive lenses at affordable prices.

Essilor Varilux XR Series the first eye-responsive progressive lens powered by behavioral artificial intelligence. These lenses are the only progressive lenses with Xtend Technology, a breakthrough design calculation that significantly extends the area of sharp vision within arm’s reach—patients no longer have to tilt their heads to find “just the right spot.” They also feature Nanoptix® Technology, which virtually eliminates any off-balance feeling, leaving the wearer feeling confident on the go.


Nikon Seemax Ultimate is a revolutionary breakthrough where the approach to progressive lens design is re-invented, and each lens is co-designed with you and your patient based on the wearer’s unique vision insights (their needs, preferences and viewing habits) for the ultimate viewing experience. Thanks to this exclusive INSIGHTS TECHNOLOGY, aberrations are reduced to the maximum and remaining ones are made virtually invisible to the wearer by canceling out the type of aberrations he is most sensitive to.

ActiveDVE3 stabilizes the power variation in the mid-distance zone of the lens where the power variation is the strongest. The Intermediate Vision Booster Technology reduces the aberrations in the intermediate zone thus widening the intermediate vision field.
