How Progressive Lenses Work

Author | 03.08.2007 | Category Contact Lenses

One of the unfortunate side effects of aging is that the crystalline lens in the eye loses some of its flexibility, making it difficult to focus on objects at different distances. Bifocal lenses were an attempt to help people focus by creating two separate zones in the glasses with different strengths that allowed people to focus on objects both close by and at a distance, but this still left the middle distance unclear. Read how progressive lenses work to provide a better solution for people who suffer from this problem.

Progressive lenses have a gradient corrective range, with the top of the lenses having only minimum strength and the bottom reaching the maximum prescription strength. Patients can bring objects at any distance into focus by moving their heads until they find the right correction strength for the object.

Progressive eyeglass lenses have many advantages over bifocals or trifocals including:
• There is no sudden, dramatic change from one zone to the next, which makes for a smoother transition between focus ranges.
• The proper focus in any range from far to near can be easily achieved.
• Glasses with these lenses look more attractive, and are not immediately identifiable as multifocal lenses.

While progressive lenses are the most effective way of dealing with age-related focus problems that we have today, they do have drawbacks as well. Most notably, the variety of different focuses can be disorienting for some people. Progressive corrective lenses are most effective when looking directly at an object; objects that are seen off to the side will appear to be distorted. While most will adjust to the lenses with time, some people simply cannot tolerate the distortions.

If you are currently using bifocal or trifocal lenses, progressive eyeglasses may be a huge improvement for you. Speak with your eye doctor to try these remarkable lenses.
