Spectacles for Presbyopia
If you have perfect unaided distance vision or perfect corrected distance vision, when you reach about the age forty years, you will very likely lost some degrees of eyes ability to focus on near object clearly and comfortably, this condition is called Presbyopia.
Single vision spectacles prescribed for only reading purposes can solve this problem. However, for many others this reading only spectacle, which cannot be used for seeing distance and walking around in the office or at home, is very inconvenience for regular uses.
Bifocal spectacles have distinctive line dividing the upper segment for distance purposes and the lower segment for near visual tasks.
They allow the wearers to see distance and near objects with the same spectacle.
The following disadvantages are the main causes of the bifocal spectacles for not being commonly accepted by the wearers:
Progressive power spectacles provide undisrupted clear vision at all distances.
Progressive power lenses are designed so that a smooth, continuous and seamless progression of lens power changes vertically, from upper distance portion down to the lower intermediate and close up portion, providing undisrupted clear vision at all distances, and eliminated all the main disadvantages of bifocals.
The multi-function progressive power spectacles are the most commonly used by Presbyopes, whether for occasional or as constant visual needs.
Majority of first time progressive power spectacle wearers take just a week or so to get use to the mild peripheral blurriness and swing or floating feeling with the premium progressive power lenses made by the major established manufacturers.
For some requiring higher performance progressive power spectacles and the small number wearers previously failed to adapt to the premium progressive powers, the advanced high performance progressive power lenses produced by advanced digital wave-front technology, offer a wider field of vision, minimised unpleasant swim and sway effects, allowing for natural head posture and comfort.

For younger middle age, it is much easier and need shorter time to adapt to the progressive power spectacles as a result of the mild reading-add power that built in the lens, and this also make it easier to adapt to the higher reading-add powers in the older age.
