Understanding Astigmatism
What Is Astigmatism?
Astigmatism is a common refractive error caused by an irregular curvature of the cornea or lens. Unlike myopia (nearsightedness) or hyperopia (farsightedness), which affect the overall shape of the eye, astigmatism causes the cornea or lens to be shaped more like a football rather than a soccer ball. This irregular shape prevents light from focusing properly on the retina, leading to blurred or distorted vision at all distances.
Symptoms of Astigmatism
Common symptoms of astigmatism include:
- Blurred or distorted vision
- Eyestrain or discomfort
- Headaches, especially after reading or using digital devices
- Difficulty seeing at night
- Squinting to see clearly
Diagnosing Astigmatism
Astigmatism is diagnosed through a comprehensive eye exam that includes:
- Visual Acuity Test: Measures how clearly you see at various distances using an eye chart.
- Keratometry: Measures the curvature of the cornea.
- Refraction Assessment: Determines the exact prescription needed for corrective lenses.
- Corneal Topography: Provides a detailed map of the cornea’s surface curvature.
Introduction to Biofinity Toric Contact Lenses
What Are Biofinity Toric Lenses?
Biofinity Toric lenses are premium silicone hydrogel contact lenses manufactured by CooperVision. These lenses are specifically designed to correct astigmatism, offering a combination of comfort, clarity, and stable vision. The Biofinity brand is known for its high-quality materials and advanced lens technology, making it a popular choice among contact lens wearers with astigmatism.
Key Features of Biofinity Toric
- Aquaform Technology: Provides high oxygen permeability, allowing more oxygen to reach the cornea and promoting healthy eyes.
- Optimized Toric Lens Geometry: Ensures stable and clear vision by minimizing lens rotation and providing a consistent fit.
- Naturally Hydrophilic Material: Attracts and retains water within the lens, maintaining moisture and comfort throughout the day.
- Extended Wear Option: Approved for extended wear up to 7 days and 6 nights, offering flexibility for users with busy lifestyles.
Benefits of Biofinity Toric Lenses
Superior Comfort
Biofinity Toric lenses are made from a unique silicone hydrogel material that combines high oxygen permeability with excellent moisture retention. This ensures that your eyes stay comfortable and hydrated throughout the day, reducing dryness and irritation.
Stable and Clear Vision
The optimized toric lens geometry of Biofinity Toric lenses minimizes lens rotation and ensures a consistent fit, providing clear and stable vision for people with astigmatism. The lens design also enhances the quality of vision in low-light conditions, such as driving at night.
Healthier Eyes
The high oxygen permeability of Biofinity Toric lenses allows more oxygen to reach the cornea, promoting healthier eyes and reducing the risk of complications associated with low oxygen levels. The lenses are also designed to be naturally wettable, reducing the need for additional wetting agents.
Extended Wear Flexibility
Biofinity Toric lenses are approved for extended wear, allowing you to wear them continuously for up to 7 days and 6 nights. This flexibility is ideal for people with busy schedules or those who prefer the convenience of extended wear lenses.
Technology Behind Biofinity Toric Lenses
Aquaform Technology
Aquaform Technology is a patented feature of Biofinity lenses that combines high oxygen permeability with moisture retention. This technology creates a naturally hydrophilic lens material that attracts and retains water, keeping the lenses moist and comfortable throughout the day.
Optimized Toric Lens Geometry
The optimized toric lens geometry of Biofinity Toric lenses is designed to provide a stable and consistent fit. This design minimizes lens rotation, ensuring that the corrective power remains aligned with the astigmatism axis. The result is clear and stable vision, even during physical activities.
Balanced Progressive Technology
For users with both astigmatism and presbyopia, Biofinity Toric Multifocal lenses incorporate Balanced Progressive Technology. This design provides multiple zones of vision correction within the lens, allowing for clear vision at all distances.
High Oxygen Permeability
Biofinity Toric lenses are made from a silicone hydrogel material that allows up to six times more oxygen to reach the cornea compared to traditional hydrogel lenses. This high oxygen permeability helps maintain healthy eyes and reduces the risk of complications associated with low oxygen levels.
Using and Caring for Biofinity Toric Lenses
Inserting and Removing Lenses
Proper insertion and removal techniques are essential for the comfort and longevity of your Biofinity Toric lenses. Follow these steps for safe and effective lens handling:
