Making the change from Single Vision Distance lenses to Progressive Lenses

Considering making the change from single vision lenses to progressives for your spectacles? Here at Rose Optometry we are here to help choose the right lens for you.

By listening to and understanding your needs, lifestyle requirements, age, and specific visual requirements we can work through the best lens design choices for you, offering a variety of lens designs custom made to your eyes.

Single vision lenses are an ideal choice for younger customers, and for specific requirements for all age groups.

The young eye has a flexible lens to accommodate and focus your vision to a range of focal lengths. With time the lens becomes less flexible, and from around the age of forty we start to notice this effect.

Eyes that could once focus both to near and far distances with ease gradually lose that ability and we begin to notice close objects and text not able to be focused with clarity. This is termed presbyopia.

At this time reading and fine close work will be blurred and this can easily be corrected using spectacles. Single vision lenses at this time, for example reading glasses are very effective, however the need to remove them for distant or intermediate distances can be quite limiting.

Progressive lenses are designed to incorporate three zones: near focus in the lower area(e.g. for reading), intermediate focus in the centre of the lens (e.g. for computer work) and distant focus at the top are of the lens seamlessly and invisibly blended.

As there are effectively three lenses in the one lens, it can take new wearers a short period of time to adapt to the design. The earlier a person tries progressives, the better the outcome may be for ease of adaption, and very quickly the spectacle lens works with you to be able to see all ranges in focus.
