Toric Lens Power Calculator: Convert Glasses to Contacts | My Toric

"I only have my glasses prescription..." Unsure about your power?

Glasses and contact lenses sit at different distances from your eyes. Use the My Toric calculator to find the perfect prescription for your eyes.

💡 About Astigmatism Axis (AXIS)

The reason AXIS is not in the calculator is because you use the value from your glasses prescription exactly as it is! Simply check your Power (SPH/CYL) using the calculator, and for the AXIS, just select the number written on your prescription when you purchase. It’s that easy! 😊

If you find the numbers confusing, just send us a photo of your prescription! Our specialized staff will verify your power for free.
