Understanding Multifocal Contacts for PresbyopiaPresbyopia, common in those over 40, causes blurry near vision due to the lens hardening. Multifocal contact lenses can correct this by incorporating multiple prescriptions into a single lens for clear vision at all distances. Types include concentric, aspheric, and segmented bifocals. Proper fitting by an eye care professional is crucial for comfort and effectiveness. Multifocal lenses are a convenient alternative to glasses, offering a seamless vision correction experience for various tasks.
Multifocal Contacts: How do they work and are they right for you?
What is presbyopia
Those over 40 years old may notice that they are unable to focus on objects up close or that their near vision is blurry. Presbyopia is the name of this condition, which occurs naturally with age. Presbyopia, or the hardening of the lens due to the loss in elasticity of that lens, is a natural condition. The lens becomes harder and the eye can no longer focus on near objects.
What are contact lenses to correct presbyopia?
These contact lenses correct both near and distance vision. These contact lenses are able to accommodate several different prescriptions into a single lens, allowing the wearer to clearly focus on objects from a variety of distances whether they're reading or driving. Multifocal contact lens can even correct astigmatism. Multifocal lenses feature three focal points - one for reading or up-close correction; one for intermediate vision and one for distance.
Types and types of multifocal contacts lenses
Three main types of multifocal contacts are available:Concentric multifocals. These lenses feature concentric rings on the lens to allow for a gradual change from one prescription type to another. Rings are designed to alternate between near- and distance-corrections, similar to the bull's eye pattern.
Aspheric multifocal lens. Aspherics are similar to progressive lenses and provide a smooth transition between prescriptions. The prescription in the middle will gradually move as you move away from it.
Segmented bifocals. All bifocal contacts are rigid gas permeable contact lenses. These lenses are similar to bifocal glasses, where the near prescription is located on the bottom of the lens while the distance prescription is found in the upper half. The lower half of the lens is flattened in order to hold it on the eye.
Do you have a prescription for these types of lenses or not?
Contact lens prescriptions are composed of many factors. These include the power, base-curve, diameter, lens brand, etc. If your eye physician recommends rigid gas-permeable lenses, your prescription will also include color and dot information. Contact lenses come with different materials and fit. If you use contact lenses you weren't prescribed, you could experience discomfort or even serious infections. You should only wear contact lenses prescribed to you by a qualified eyecare professional. We can help you understand your prescription and determine if they are for contact lenses.

Children with progressive myopia may also benefit from wearing multifocal contacts.
Is multifocal lens right for me
People with multiple vision requirements have several options. Some people choose to use their regular reading glasses and distance contact lenses when necessary, while others carry two monovision contact lens sets (one for distance tasks and the other for near tasks). Bifocal or multifocal contacts are a convenient and natural alternative. Typically they require a little adjustment. Nevertheless, your eyes are going to learn quickly to differentiate between different prescriptions. They will then automatically start using the right prescription at the correct distance. You will no longer need glasses for many daily activities if these lenses are fitted properly.
