Base Curve
(BC,BOZR)
The base curve of a contact lens is the radius of the sphere that the back of the contact lens describes. Your eye practitioner should ensure the contact lens fits well to your cornea in order to be comfortable and to facilitate tear exchange and oxygen transmission.

Generally, if your contact lens feels lose and slides easily, a smaller base curve may work better. A larger base curve may be needed if they feel tight.
This feature will be shown at London Eyewear with the following icon:
