The trend of using multifocal and bifocal contact lenses in Maple has become a widespread phenomenon. These types of lenses are specifically geared towards enabling a clear vision before your approach your 40’s. Once you reach this age, you might feel the need to visit the eye doctor frequently to ensure that your vision and eye health is intact. You might often find yourself holding the reading material at a particular distance to make its context visible to you. Doing so, you are more likely to have presbyopia.
Bifocals or Multifocal contact lenses by Maple Optometrists – What’s the Difference?
Bifocal and multifocal lenses Maple can be customized to be soft or, they could be tailored using rigid gas permeable (GP) materials. Bifocal contact lenses are equipped with two variations of power, and each power caters to adjusting distance and near vision for several purposes.
On the contrary, multifocal lenses are equipped with progressive eyeglass lenses, and each lens is supplied with various ranges of powers that can be used to look in different directions.
Types of Multifocal Contact Lenses
Several types of multifocal contact lenses can be categorized in the following ways:
Simultaneous vision lenses
Using a simultaneous vision lens, you can correct the distance and zones of the lens simultaneously. Although this approach might sound too far-stretched, your visual system adjusts itself to the lenses, and it cancels out the power of other lenses. Simultaneous vision lenses are known as the most common types of contact lenses, and it can be further categorized into two designs:
a) Concentric ring designs
Concentric ring designs are known as bifocal lenses which are equipped with near and distance power at the core of the lenses, and they further include the rings of the distance and power enveloped by it.
b) Aspheric designs
Aspheric designs are regarded as progressive-style multifocal lenses, and its power is distributed evenly on the surface of the lenses. Few aspheric lenses are equipped with distance power near the core of the lenses, while near power is concentrated on the edges of the lenses.
Alternating vision lenses
The alternating vision lenses are known as GP multifocal lenses that bear a resemblance to the bifocal eyeglass lenses. The top section of the lenses is equipped with distance power, and the bottom part of the lenses is powered by near power.
Will Multifocal Contact Lenses by Maple Optometrists Work for Me?
Several people who have invested in and worn multifocal contact lenses have reported optimistic outcomes. However, you might be required to make certain adjustments and alternations before finalizing if the multifocal contact lenses would work for you. For instance, you might not be able to experience a clear and precise distance vision using the multifocal contact lenses or, you might have to experience glare at night time.
In certain cases, a person who is diagnosed with presbyopia might prefer monovision over multifocal contact lenses for various reasons. It should be noted that a monovision lenses use a single lens, which makes it subjected to exude one-dimensional power rather than multi-dimensional powers via using multifocal contact lenses.
In monovision, a person is assigned a single vision contact lens for one eye that pertains to the adjustment of distance vision and a single vision contact lens on the eyes that requires an adjustment for nearsightedness.
Before you finalize the type of contact lenses, you should be prescribed an approval from your optometric to ensure that your preferred contact lenses work the best for you.
