Astigmatism is a common vision condition that causes blurred or distorted vision due to an irregularly shaped cornea or lens. For individuals with high astigmatism, finding the right contact lenses is crucial for clear vision and comfort. This guide explores the best contact lenses available for high astigmatism, considering various factors such as lens type, material, and user needs.
What is High Astigmatism
Astigmatism occurs when the cornea or lens has an irregular shape, preventing light from focusing properly on the retina. High astigmatism refers to a more severe form of this condition, typically requiring specialized contact lenses for correction.
Types of Contact Lenses for High Astigmatism
Toric Soft Contact Lenses
Toric lenses are specially designed to correct astigmatism by having different powers in different meridians of the lens. They are available in various materials and wearing schedules.
Notable Options:
- Proclear Toric XR: Designed for individuals with high levels of astigmatism, offering extended range prescriptions.
- Biofinity XR Toric: Provides comfort and clarity for those with higher degrees of astigmatism.
Rigid Gas Permeable (RGP) Lenses
RGP lenses are hard lenses that provide clear vision by maintaining their shape on the eye, effectively correcting astigmatism.
Benefits:
- Sharper vision compared to soft lenses.
- Durable and long-lasting.
Considerations:
- May require a longer adaptation period.
Hybrid Lenses
Hybrid lenses combine a central RGP zone with a soft outer skirt, offering the clarity of RGP lenses with the comfort of soft lenses.
Advantages:
- Enhanced comfort for RGP lens wearers.
- Stable vision correction for high astigmatism.
Scleral Lenses
Scleral lenses are large-diameter RGP lenses that vault over the cornea and rest on the sclera, providing excellent vision correction for irregular corneas.
Ideal For:
- Individuals with high or irregular astigmatism.
- Those with keratoconus or post-surgical corneas.
Factors to Consider When Choosing Contact Lenses
Prescription Requirements
Ensure that the lenses are available in the necessary cylinder and axis parameters to correct your level of astigmatism.
Comfort and Material
Consider lenses made from materials that offer high oxygen permeability and moisture retention to enhance comfort, especially for extended wear.
Wearing Schedule
Choose between daily, bi-weekly, or monthly lenses based on your lifestyle and maintenance preferences.
Eye Health and Lifestyle
Discuss with your eye care professional about any specific eye health concerns or lifestyle factors that may influence lens choice.
Conclusion
Selecting the right contact lenses for high astigmatism involves considering various factors, including the severity of astigmatism, lens material, comfort, and lifestyle needs. Consulting with an eye care professional is essential to determine the most suitable option for your specific condition. With the appropriate lenses, individuals with high astigmatism can achieve clear and comfortable vision.
