Unique design calculation in Varilux® X Series™ lenses that allows the wearer to see multiple distances through a single point in the lens, significantly extending vision within arm's reach so wearers no longer have to move their heads to find the “just the right spot” in the lens.

Varilux is a brand name belonging to Essilor International, a producer of corrective lenses. The first version of the lens was invented by Bernard Maitenaz and released in 1959, and was the first modern progressive lens to correct presbyopia.

Varilux progressive lenses offer a seamless transition between near and far vision, removing the need for multiple pairs of glasses. This is because the lenses have a gradient of power that allows you to see clearly at all distances.

Varilux S Series lenses are the most advanced progressives available today. While they provide all of the usual benefits of Varilux lens designs, they also eliminate distortion and provide better edge-to-edge clarity.

How do I know that I have genuine Varilux® lenses? Varilux® lenses come from the manufacturing laboratory with a Varilux® certificate of authenticity card. If you do not receive a certificate of authenticity card with your Varilux® lenses, please consult your eye care professional.

Varilux X Series 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.”

The average cost of Varilux is between $129 to more than $400 for the lens alone. A prescription may cost you about $60 to $125 without insurance. If you prefer coating to reduce glare and prevent harmful blue light, it may cost you an additional $50 and $100.

Third, lenses come in power from Company, ask for those wrappers, where in you can identify lenses name, Crizal UV, FUV etc etc not to forget index of lens.
