About Contact Lens Calculator
Our mission is to provide accurate prescription conversions and helpful resources for contact lens users.
Our Story
Contact Lens Calculator began with a simple goal: to make it easier for people to convert their glasses prescriptions to contact lenses accurately.
Founded by a team of optometrists and web developers, we recognized that many people were ordering contact lenses online without fully understanding how to convert their prescriptions correctly.
This led to incorrect orders, wasted money, and even potential eye health issues. We set out to create a free, accessible tool that would help people make informed decisions about their contact lenses.
Today, our calculator is used by thousands of people worldwide to convert their prescriptions with confidence.

Frequently Asked Questions
Answers to common questions about our calculator and contact lenses.
Is your calculator's conversion accurate?
Our calculator uses scientifically validated formulas based on optical principles to convert glasses prescriptions to contact lens prescriptions. While the calculations are accurate, every eye is unique, and your eye care professional may make additional adjustments based on your specific needs.
Do I still need to see an eye doctor?
Yes, absolutely. Our calculator provides an estimated conversion, but a proper contact lens fitting by an eye care professional is essential. Contact lenses sit directly on your eye and require professional fitting to ensure proper movement, oxygen transmission, and comfort.
How often should I update my contact lens prescription?
In most cases, contact lens prescriptions expire after one year. Regular check-ups are important not only for vision correction but also to monitor eye health, as contact lens wear can sometimes lead to complications if not properly managed.
Is your calculator free to use?
Yes, our calculator is completely free to use. We believe that everyone should have access to tools that help them make informed decisions about their vision care. We sustain our site through affiliate partnerships with reputable contact lens retailers.
