Wah . Got so many diff types . Definitely mine is the low end range.. Hopefully can last long enough and be comfortable to wear..For the price with frame is considered OK (on the lower side).
Of course Essilor also have many different type of progressive lens. Essilor low end range of progressive lens start from Liberty and the next range up is Comfort continued with Physio and Ipsio but the last few can actually be replaced by their S Series of progressive lens like Design, 3D and 4D. I always think the entry level of progressive lens from Essilor is the Comfort range. It is good to start from the lower level (also cheaper) and move up. In time you will realized the benefit of the better range of progressive lens.
