Contact Lens Base Curves and Diameters

Find the base curve (the curve of the back surface of the contact lens e.g. 8.4, 8.5, 9.0) and diameter (the diameter of the contact lens which is a number between 13.0 to 15.0) of your contact lenses using the list below.

When changing to a different contact lens type or brand the combination of base curve and diameter along with the material of the contact lenses all contribute to how the contact lens sits on the eyeball. Badly fitting contact lenses can damage the surface of the eye; It is therefore extremely important that a qualified optometrist checks the fit of the contact lenses on the eye to ensure the lens is repositioning itself correctly after blinking, is not too tight or too loose and is providing optimum visual accuity.
