Multifocal contact lenses are another tool to help you achieve sharp, clear vision at all distances. An advancement from bifocal contact lenses, multifocal lenses are proof of how far the technology and design of contact lenses has come. With multifocal lenses, you can see at various distances clearly with just one pair of contact lenses.
Multifocal contact lenses can help to correct refractive errors, especially those that come about during the ageing process like presbyopia. Also known as varifocal contact lenses for this reason, they are a great solution for those struggling with their eyesight. Camden Opticians take a closer look at what they are and how they work.
Treating presbyopia
Presbyopia is a common vision problem as we age, whereby the lens loses some of its elasticity. It affects everyone from the age of around 40, and it can make close-up objects more difficult to see. For someone that already had myopia (short-sightedness), presbyopia will mean that you now need corrective lenses for two different vision problems.
What do multifocal contact lenses do?
Multifocal contact lenses typically include multiple prescriptions in one, designed to allow for different lens powers. This helps the wearer to see clearly up close, mid-range distances and further distance.
These lenses have progressed from bifocal contact lenses, which had a sharper change between two vision zones, often with an invisible horizontal line down the middle of the lens. Multifocal contact lenses have a much more gradual change with a smoother transition between the different powers.
How are they designed?
Multifocal lenses are most commonly designed in a set of concentric circles of lens powers. There are also other blended designs, which are able to keep near and distance prescriptions close to the centre of the eye. This can help to mimic a more natural viewing experience.
Multifocal contact lenses are available in both soft materials and a rigid gas permeable material. Rigid gas permeable contact lenses are more durable and less likely to tear or break. They are designed to be more breathable, allowing more oxygen through the lens to reach the eye. This can be more beneficial for the overall health of your eyes.
How to get multifocal contact lenses
It’s important to remember that your glasses prescription and contact lens prescription are not the same. So, if you already wear glasses, you will need to get an up-to-date contact lens assessment to ensure you are wearing the right lenses for your vision needs. Typically glasses sit further away from your eyes and will have different parameters to take into account.
You can get both daily and monthly multifocal contact lenses, and choosing the right one can depend on your own personal preferences.
Look for a local optician who can offer eye examinations and contact lens fitting services, and they will be able to explain your options. Many opticians will also help you with an eye care plan, whereby you can save money on your contact lenses.
Don’t forget that you should make hygiene and safety a priority when wearing contact lenses. Solutions and drops can help to keep your contact lenses in good condition, making sure they are disinfected and cleaned.
Thanks for the useful information. For me now it is very important because I need to buy lenses or glasses because I have poor eyesight. I like the yellows at Ocuwear . I like these glasses because they are very stylish in the first place. I believe that glasses are a very important part of the image and an accessory that creates a good style for you.
