Over 40 (presbyopia)
Presbyopia is a natural part of the aging process and affects everyone over forty years of age. People usually notice the condition around age 45, when they realise that they need to hold reading materials further away in order to focus on them.
The process by which the eye increases its power to see things clearly close up is called accommodation. Accommodation can be described as the “auto focus” feature similar to that on a camera. Just as a camera lens needs to be moved back and forth to focus clearly on the object being photographed, an eye adjusts its power to focus on things up close or in the distance.
As presbyopia starts to develop, the eye power becomes a “fixed-focus” losing its ability to “auto-focus” on things at different distances, providing clear vision only at a particular distance. If the vision is corrected for distance, seeing things close up becomes a challenge with the distance vision correction. The reverse also holds true. When the vision for close up distance for people with presbyopia is corrected, distance vision will be blurred.
The unique Duette® Progressive hybrid design eliminates the instability and soft optics issues of other multifocal contact lenses. You’ll never have to juggle multiple vision solutions – glasses and bifocals, or bifocals and contacts – again. The precision rigid gas permeable centre and the soft contact lens skirt of the new revolutionary Duette Progressive hybrid contact lens provides clear, crisp, consistent vision at distance and close up. The irregularities of the front surface of the eye that are typically transferred to the front surface of a soft contact lens are neutralised by the tear film between the eye and the rigid gas permeable centre. All nearsightedness, farsightedness and astigmatism are corrected by the distance power, while the crisp optics of the close up power provides simultaneous computer and reading vision with minimal interference with distance vision. With the Duette Progressive contact lens, now you can experience ageless vision near and far.
If you are experiencing blurry vision while reading because of presbyopia and want to experience ageless vision near and far and clear, crisp vision when looking at things close up or at a distance, ask your eye care practitioner about the Duette Progressive lens.
