Seamless Vision: Experience All-Distance Clarity with BOSTON™ Multivision RGP
The BOSTON™ Multivision is a high-precision multifocal Rigid Gas Permeable (RGP) contact lens. As we age, the eyes' ability to adjust between different distances diminishes, leading to difficulty in seeing close objects (presbyopia). By integrating multiple viewing zones into the lens, BOSTON™ Multivision allows wearers to switch seamlessly between reading, computer work, and driving without the need for reading glasses or awkward head tilting.
Core Technology & Benefits
-
Progressive Posterior Design: This is the core patented technology of the Multivision lens. By incorporating a gradual change in curvature on the back surface, the lens merges distance, intermediate, and near vision zones. This design utilizes the natural movement of the RGP lens and pupil adjustments to provide a continuous and natural visual transition.
-
Exceptional Optical Sharpness: Being a rigid lens, it provides a level of clarity that soft multifocal lenses often cannot match. The firm material creates a consistent optical surface that compensates for corneal astigmatism, ensuring high-contrast vision even in dim lighting.
-
High Oxygen Delivery: Utilizing classic BOSTON™ high-Dk fluoro-silicone acrylate materials, the lens ensures that the cornea can breathe freely all day. This is particularly crucial for mature wearers, as it maintains long-term ocular health and comfort.
-
Dynamic Stability: The lens geometry is meticulously calculated to maintain excellent centration during blinking. This prevents "image jump" or blurring caused by excessive lens movement, keeping your vision stable.
QNA
1. Can this lens truly provide clear vision at far, intermediate, and near distances?
Yes. It integrates different focal powers. When looking straight ahead at a distance, light passes through the distance zone. As you look down at a book or computer, your eye position shifts and your pupil constricts, automatically engaging the intermediate and near zones for seamless vision.
2. Is there an adaptation period when switching from standard RGPs to Multivision?
There is a period of neurological adaptation. Your brain and eyes need time to process the new visual signals and learn how to utilize the different zones. Generally, with 1 to 2 weeks of consistent wear, most users adapt well to the multifocal pattern.
3. Does this lens correct astigmatism?
Yes. As an RGP lens, it utilizes the "tear lens" effect to effectively correct corneal astigmatism. If you have both astigmatism and presbyopia, this lens often outperforms soft multifocal alternatives.
4. Are there special care requirements for these multifocal lenses?
The basic care routine is the same as for standard RGPs; using BOSTON™ professional care systems is recommended. Due to the precision of the viewing zones, handle with care during daily cleaning to avoid surface scratches that could interfere with optical performance.
5. Who is the ideal candidate for BOSTON™ Multivision?
If you are over 40 and find that your current single-vision contacts make close-up tasks (like reading phone screens or menus) difficult, or if you wish to avoid the constant switching to reading glasses, this multifocal RGP is an ideal choice for a premium lifestyle.
