See What You Are Missing
Lots of people come to see me for advice about varifocal glasses they have bought elsewhere.
"I can’t get on with them, the vision is very narrow, the vision seems distorted, everything swims when I walk, I can’t walk down stairs etc"
I really want to share the advice I give to my clients to give you a better understanding of why you should be wearing varifocals, are they right for you? Why do some people struggle to use them?
And most importantly, with recent advances in computerised lens design technology these problems have been nearly eliminated.
As we get older, especially after the age of 45, our reading vision starts to deteriorate and we invariably glasses start to be a necessity (if they are not already). This change also means your eyes can’t change their focal point easily. Single vision glasses have one fixed focal point and if you need more than one focal point then your single vision glasses will suddenly start to be very limited.
Varifocal lenses have a specially blended surface so that the focus of the lens varies depending on the distance that you want to look at. Things further away tend to be located straight ahead while things closer tend to be in the lower field.
The clever design of varifocals means that when I look straight ahead I can see further away and as I move my eyes down the lens I can see closer objects clearly too.
The blending has the important added advantage that the vision is also clear for things that are in the intermediate view, not as close as reading but closer than distance, such as using a computer or visiting a gallery or even just seeing the food on your plate. Take note of the device you’re reading this information on and the distance you’re away from it and what position it is in your field of view.
So this sounds perfect for restoring the natural vision we were all used to and allowing us to see freely at lots of different distances, especially when our work and lifestyle involves such a heavy use of our eyes. Why do people have problems with varifocals then?
Well, the way that the focal points are blended on a varifocal to eliminate the line means that the sides of the surface of the lens have to be more curved than a single vision lens, This makes the area at the sides of the vision appear distorted and can even induce movement when looking from side to side.
Older lens designs used manual calculations and tools to make these lens so the area of distortion could never be controlled accurately. As a consequence these lenses were very cheap to produce but had large amounts of distortion and the cause of many of the difficulties that people have traditionally experienced with lenses. This is particularly apparent with any type of “budget” varifocal, some people can manage with reduced vision from the sides but its not the best way to get the most from your vision.
The other most common problem is that wearers aren’t taught properlyhow to use the lenses to learn how to adapt to them. The difficulties and visual distortion they might experience hasn’t been explained to them. At Central Vision Opticians whenever you buy varifocals we’ll always take the time to demonstrate the right way to use varifocals properly so you’ll quickly be getting used to having great vision again.
Finally, were the measurements taken accurately? Having a lens where the power varies across the lens could cause blurry vision if the position of the lens is not precisely measured and manufactured.
The most exciting part about new technology that has an impact is the use optical computer sensors to measure the surface accurately and design a varifocal lens that is perfectly matched to your prescription and when this is combined with brand new computer controlled precision manufacturing technology, the clear region of the lens is widen significantly with any residual distortion pushed right to the extreme sides.
