Multifocal contact lenses are expensive
What are multifocal contact lenses?
Multifocal contact lenses were developed to combine different lens powers in one lens in order to make clear vision possible at different distances. But how does it work and would it make sense for you? We help you understand multifocal contact lenses and think about whether they are right for you and your ametropia.
What are multifocal lenses?
Multifocal lenses are visual aids that have several visual strengths processed in one lens. There is usually a prescription for very close objects, a prescription for normal objects further away, and then prescription for the medium distance. This configuration especially helps patients with presbyopia to correct age-related visual impairments, in which the body's own lens of the eye can no longer focus on nearby objects.
What is the difference between multifocal and bifocal contact lenses?
Multifocal lenses are designed with a graduated transition between a visual strength for close reading at one end and a visual strength for vision at normal distance at the other. They are therefore very similar to varifocals. Instead, bifocal contact lenses have a sharp edge between the nearsighted and farsighted areas of the lens. What you can cope with better can be found out together with a contact lens specialist and by trying it out.
Types of multifocal lenses
Multifocal lenses are made of both soft lens material and dimensionally stable (rigid gas permeable, RGP or hard) contact lens material. Depending on the eye and everyday life, one material can be more suitable than the other.
There are two main types of multifocal contact lens design. The most common is a set of concentric circles with different prescriptions for different distances. There are also superimposed designs where the near and television powers are close to the center of the eye, mimicking a natural viewing experience by correcting the specific points of deviation of the eyes.
The choice of multifocal lenses
How do you know if multifocal lenses make sense for you? Here are a few pros and cons to consider before and during your visit to your contact lens specialist.
Multifocal lenses offer a number of advantages, including:
- Better visual acuity for near to far
- A less abrupt transition from one prescription to another
- The ability to see without additional glasses in most conditions
- Multifocal lenses offer a lot, but may include:
- Difficult to adjust due to the different viewing experience
- During the adaptation phase, accompanied by blinding light with night vision and veiled or shadowy vision
- More expensive due to the increased complexity of the design
- Alternatives to multifocal lenses
If multifocal lenses don't sound like they are a good fit for you, there are a number of other options for treating ametropia such as presbyopia. For example:
- The combination of reading glasses with normal contact lenses
- Monovision contact lenses
- Bifocal contact lenses
- Surgery or lens implants, if your contact lens specialist recommends it
