Understanding Astigmatism and Multifocal Lenses
Astigmatism is a common refractive error caused by an irregularly shaped cornea. This irregularity leads to blurred or distorted vision, especially at varying distances. Multifocal lenses combine different prescriptions in one lens, addressing both astigmatism and presbyopia simultaneously.
How Multifocal Lenses Work
Multifocal lenses contain multiple zones, each designed for different viewing distances. The design allows for seamless transitions between distances, enabling clear vision for reading, intermediate tasks, and distance viewing.
The Benefits of Multifocal Contact Lenses
- Convenience: They eliminate the need for multiple pairs of glasses.
- Improved Comfort: Soft multifocal lenses provide comfort, especially for those with dry eyes.
- Aesthetic Appeal: Contacts can be more aesthetically pleasing than glasses.
Types of Multifocal Contact Lenses for Astigmatism
There are primarily two types of multifocal contact lenses designed for those with astigmatism: Toric Multifocal Lenses and Multifocal Toric Lenses.
Toric Multifocal Lenses
These lenses are designed specifically for astigmatism and can correct vision at multiple distances. They maintain their orientation on the eye, ensuring that the correct prescription aligns with the visual axis.
Multifocal Toric Lenses
These lenses combine the features of toric lenses for astigmatism with the multifocal design, allowing for clear distance and near vision. They are available from several brands, including Proclear and Bausch + Lomb ULTRA®.
Choosing the Right Multifocal Lens
Selecting the right multifocal lens involves several considerations:
1. Prescription Accuracy
Ensure your prescription is up-to-date. An accurate prescription is essential for achieving the best vision.
2. Lens Material
Soft lenses are generally more comfortable and easier to adjust to, while rigid gas permeable lenses may offer sharper vision but can take longer to adapt to.
3. Lifestyle Needs
Consider your daily activities. For example, those who spend a lot of time on the computer may require lenses optimized for digital device use.
4. Fitting Process
A professional fitting is crucial for toric lenses, as they must align correctly on the eye to provide optimal vision.
