Base curve and diameter of contact lenses

When searching for contact lenses, it’s important to know which ones are suitable for you. Apart from the contacts’ power, also known as PWR or DPT/SPH, you need to know the base curve (BC) and diameter (DIA) of the lens.

We are often asked the following questions:

  1. What is the base curve of my contact lenses?
  2. What is the diameter of my contact lenses?
  3. Can I use a different brand of contact lenses with the same power?

We have prepared for you the following table that will help you in the process of determining how to choose the base curve of contacts. In addition, this detailed comparison table will help you find the exact information you’re looking for, like the base curve and diameter of each lens, as well as the power range, price and the contact lens material.

Don’t forget to discuss your choice with a specialist.

Should you still have queries about any of the listed contacts or if the details on your prescription don’t match any of the contacts listed, don’t hesitate to call on 180 081 4141 or email us at info@lentiamo.ie.
