Patients with astigmatism need lenses with different optical powers at different points that must be oriented in just the right way to correct vision. CooperVision® toric lenses are both stable and accurate due to Optimized Ballast Design (or Optimized Toric Lens Geometry™). This type of design is multifaceted to ensure optimal visual acuity, fit, and comfort. The geometry of the lens and its wide ballast band quickly orient the lens for better performance and simple fitting. A uniform horizontal ISO thickness also enhances lens stability and provides a consistent fit across the power range. A larger toric optic zone provides clear vision over a wide range of lens powers. Finally, a smooth, junction-less surface helps maximize comfort on every blink.
