What is Presbyopia?
Presbyopia occurs as we age and causes the eye’s lens to thicken and lose its mobility. This results in a lessened ability to focus effectively on close-up objects.
Tasks such as close reading and using a mobile phone can be made much harder with presbyopia. They often result in headaches, tiredness and eye-strain.
Presbyopia is age related and there is no official cure for it. Monitoring your eye health and living a healthy lifestyle may help delay the onset of presbyopia.
There is a popular belief that you can only wear prescription glasses if you require a varifocal lens to correct presbyopia. However this is untrue. There are in fact contact lenses available if you require a varifocal lens.
You can purchase these lenses as daily, two-weekly, monthly or yearly lens. In addition to this, you can choose a lens material to suit a soft or rigid design.
We also stock standard hydrogel and silicone hydrogel lenses for presbyopia. Due to the comfort they provide, we would recommend these over rigid gas permeable lenses. However, it's best to consult with an eye care specialist before making your decision.
How to adapt to varifocal contact lenses?
Adapting to varifocal lenses is no different from wearing any other lens. The first few days, your eyes will be adjusting to having a new corrective lens in your eye. For varifocal lenses in particular, your eyes are adjusting to focusing while wearing a lens with more than one prescription. Your eyes take time to utilise the segment of the lens needed to focus on a particular object and distance.
You may notice the feeling of the lens, or have trouble inserting and removing the lens. This usually clears after a few days and practice makes perfect when wearing lenses. You can read our full guide on inserting and removing contact lenses . If you experience continuous discomfort and issues with visual clarity, it is highly advisable that you speak to your optician.
What types of varifocal contact lenses are available?
There are a range of contact lens designs for varifocal use. The most popular type features an aspheric design. Aspheric contact lenses position both the short and long-distance in front of the pupil, blending multiple prescriptions together. This ultimately means that your eyes are able to decide which prescription to use to view each object.
Concentric varifocal lenses?
Varifocal contacts with concentric circles are also available. These offer your standard prescriptive correction through the centre of the lens. They offer a gradual transition between prescription as the rings alternate distance and near corrections.
