Varifocals are the solution for correcting the vision problems associated with presbyopia. Many people realise they need varifocals (or bifocals) when they start experiencing blurred vision while doing close-up work like reading, sewing, using the computer or watching television.
Other symptoms of the condition include headaches or eye fatigue, as well as difficulty seeing in dim light.
Presbyopia and the need for varifocals is generally caused simply by the aging process. The symptoms generally start to appear between the ages of 40 and 50.
It's thought that people begin to experience presbyopia due to the fact that the lens of the eye continues to grow throughout their lifetime and that at some point the ciliary muscles that control the lens begin to have difficulty moving it.
Whatever the exact causes of this vision condition, a large proportion of adults will eventually need to correct the blurry sight caused by presbyopia. Advances in vision correction technology, mean that a variety of options exist, including contact lenses, spectacles and laser eye surgery.
If you have ever used varifocal eyeglasses, you'll have noticed that the lens has two different surfaces. The bottom part of the lens is designed to help the wearer see items that are up close, while the top part of the lens is for everything else. Just like the lenses in spectacles, varifocal contact lenses have two different prescriptions within a single lens.
This is called simultaneous vision and it works by allowing you to see objects that are near and far away at the same time. Your eye will easily adjust to this type of lens and you will be able to see clearly.
For those who need varifocal contact lenses, there are many types of contacts to choose from. The right selection will depend on your specific vision requirements, your lifestyle and your own personal preferences.
If you're looking for ease-of-use, disposable varifocal lenses might be the best solution. These are available in designs that last a single day, for example, Focus Daily progressives, or a month, for example AirOptix Multifocal.
If you would like more information about correcting your vision, the best thing to do is contact an eye care specialist. They can discuss your specific requirements and provide advice on which lenses are the right option for you. Varifocal contact lenses are complex to fit and will require 2-3 weeks to fully adapt to.
