Multifocal contact lenses are designed to target vision at variable distances from the wearer with various lens powers. But how does this function, and is it sensible for your eyesight? We will assist you in learning about multifocal contacts and how to determine if they are appropriate for your needs.
What are Multifocal Contact Lenses?
Multifocal contact lenses contain multiple prescriptions all in one lens. There is typically a prescription for very near objects, one for normal objects viewed at a distance and then for objects viewed at intermediate distances. This apparatus helps individuals with presbyopia rectify age-related vision issues in which the eye can no longer focus on near objects.
What is the Distinction Between Multifocal and Bifocal lenses?
Multifocal contact lenses are designed with a gradual transition between prescriptions for close reading and normal distance vision. They closely resemble progressive eyeglasses. In contrast, bifocal lenses have a sharp border between the near and far vision prescription portions.
Multifocal Contact Types
Soft and rigid gas permeable (RGP or firm) lens materials are available for multifocal contact lenses.
There are two primary designs for multifocal contact lenses. A set of concentric circles of lens powers prescribed for varying viewing distances is the most typical. However, blended designs maintain both the near and far prescriptions close to the centre of your eye and simulate a natural viewing experience by correcting the aberrations in your eyes.
Selecting Multifocal Contacts
How do you determine if multifocal contacts are appropriate for you? First, consider the following pros and cons before and during your visit to the eye specialist.
Benefits of multifocal lenses
Multifocal lenses provide a variety of advantages, including:
- Better visual acuity for the range of near to far distances
- A more gradual transition between prescriptions
- The capacity to see in most conditions without additional correction
Negative aspects of multifocal lenses
Multifocal contact lenses offer a great deal of functionality, but they can also be:
- Different viewing experience makes adaptation more challenging.
- During the period of adaptation, nocturnal glare and indistinct or shadowed vision are present.
- Costlier due to the increased complexity of the design.
Alternatives for Multifocal Contact Lens
If multifocal contact lenses do not seem like a suitable match, there are other options, such as:
- Combining reading spectacles and standard contact lenses
- Monovision contact lenses
- Bifocal contact lenses
- Surgical correction or lens implantation advised by your physician
Your ophthalmologist is your greatest ally when contemplating contact lenses and other eye care decisions. They will assist you in identifying the most appropriate corrective options for your lifestyle and will evaluate you within the first few months to ensure that the selection is appropriate.
