How Do Toric Lenses Work?
Unlike regular contact lenses, which have a uniform curvature, toric lenses have different curvatures at different meridians of the lens. This unique design helps focus light correctly, correcting the distortions caused by astigmatism.
Key Features of Toric Lenses
- Custom Power Zones – Different prescriptions in different areas of the lens help correct astigmatism.
- Stabilization Mechanisms – Prevents the lens from rotating and ensures clear vision.
- Material Variety – Available in soft, rigid, and hybrid materials to suit different preferences.
Types of Toric Lenses
1. Daily Disposable Toric Lenses
These lenses offer a hassle-free option for users who prefer fresh lenses every day. They eliminate the need for cleaning and maintenance.
2. Monthly and Bi-Weekly Toric Lenses
Designed for long-term use, these lenses require proper cleaning and storage. They are cost-effective and available in different materials.
3. Rigid Gas Permeable (RGP) Toric Lenses
RGP lenses provide sharper vision and are durable. They work well for individuals with high astigmatism but require an adaptation period.
4. Hybrid Toric Lenses
