BOZD
(Back Optic Zone Diameter) |
 |
| The BOZD (Back Optic Zone Diameter) is the diameter of the back optic zone (front or back) of a contact lens measured to the surrounding junction. The BOZD depends mainly on pupil size and is usually chosen to be 1.50mm larger than pupil size. A larger BOZD gives a greater sag of contact lens and therefore a steeper fitting but a smaller BOZD is often chosen with a toric cornea to reduce the area of mismatch. |
