What are Progressive Lenses by Essilor?

Essilor - Seeing the World BetterIf you are over 40 and are experiencing gradual vision loss at distance and close ranges, chances are you are experiencing presbyopia, the common gradual loss of near and distance vision. Essilor lenses offer you more choices today than ever before. You don’t have to carry a separate pair of glasses for reading or wear lined (flat top) bifocal lenses as previous generations have used. These lined (flat top) bifocals are unflattering and can be replaced with progressive lenses.

Progressive lenses offer an easy transition from distance vision, to intermediate vision and to near vision, and they supply all the in-between corrections as well. This means that instead of having just two different viewing zones such as near and distance from bifocals, progressive lenses can correct vision at multiple distances; distance, intermediate and near correction (from bottom to top). Progressive lenses ease eye strain when compared with traditional bifocal lenses, and provide a more natural vision correction.

The world’s very first progressive lens, invented in 1959, was a Varilux lens. Since the first progressive lens was invented, Essilor has continued to innovate and set a new standard of performance in vision care for patients with presbyopia. Varilux lenses are one of the top prescribed progressive lens by eye care professionals around the world.

Essilor offers many options for their lens materials, each with their own advantages and disadvantages. The plastic (CR-39) lens, a 1.50 index thickness, is very affordable, has good optical clarity and is easily tinted. The polycarbonate lens, 1.59 index thickness, is the thinnest material available. They are light weight, block UV light and are the best impact resistant lenses. High index plastic lenses such as 1.60, 1.67 and 1.74, like the CR-39 lens, are great for people with high power prescriptions. They have good optical clarity and are easily tinted. Each of these lenses can also be produced in a transition lens which transitions from light to dark as the wearer goes from inside to outside.
