Progressive lenses

Around the age of 40-50, most people start to have difficulty focusing at close range. The first indication that something is changing is that your single vision lenses can no longer be satisfactorily used for focusing on small print or near objects. For example, you may find yourself having to strain to read a menu. So you compensate by holding printed materials further and further away to bring them into focus. This is a sign of a natural eye condition that everyone faces sooner or later. The condition is called presbyopia. Presbyopia is a natural universal condition, diminishing the eyes ability over time to focus on near objects. Our close-up sight is what's affected at first. And within a few years, our mid-distance vision from 2-10 feet is also affected.

Presbyopia can be corrected with proper diagnosis and corrective lenses. And while many types of lenses can help with some of the symptoms of presbyopia, only progressive lenses allow you to see near, far and everything in between with one pair of lenses. Multi-focal progressive lenses are a better solution in many instances because they offer the crispest, smoothest, most comfortable vision at all distances.

Choosing the right frames.

Multi-focals (or graduated or progressive lenses) are a form of spectacle lens. They contain three powers- the top portion of the lens for distance vision, the central portion for intermediate vision (such as for computer use), and the lower portion for reading. The powers gradually change down the lens, so that there are no visible markings on the progressive lens.

Because of the multi-vision zones you need a frame with greater depth to accommodate the different zones. Our optometrist will evaluate the which frames are suitable for you and progressive lenses. Selected frames need about 16-18mm below the centre of the eye when looking straight ahead. This allows for an adequate zone for reading.

Adapting to progressive lenses

Normally a quick adaptation period anywhere from minutes to a few days is required when you get your first pair of prescription eye glasses that are fitted with progressive lenses. Some people with strong prescriptions do take a bit longer to adapt to the progressive lenses.

Manufacturers are aware of the fact that not everyone will be comfortable wearing progressives, so most offer a trial period of a few weeks during which you can exchange the progressives for lined bifocal lenses or single vision reading glasses if you are not able to wear the progressives successfully.
