Use the CooperVision Toric Lens Calculator to determine the appropriate prescription for your toric lenses. This calculator is designed to help you input your sphere, cylinder, axis, and add power values to generate a final prescription tailored to your vision needs.
Understanding Toric Lenses
Toric lenses are specially designed to correct astigmatism, a common vision condition caused by an irregularly shaped cornea. Unlike standard spherical lenses, toric lenses have different optical powers in different meridians of the lens, allowing them to provide clear vision at all angles. This unique design is essential for individuals with astigmatism, as it helps to focus light more effectively onto the retina.
How to Use the Calculator
To use the CooperVision Toric Lens Calculator, follow these steps:
- Input your sphere value, which indicates the degree of nearsightedness or farsightedness.
- Enter the cylinder value, which measures the degree of astigmatism.
- Specify the axis, which is the orientation of the astigmatism in degrees.
- Provide the add power if you require multifocal lenses.
- Select the lens type based on your wearing schedule.
- Click on “Calculate” to generate your final prescription.
