| Contact Lenses 101: Diameter |

Diameter in Contacts PrescriptionDiameter in contact lens prescriptions refers to the overall size of the contact lens. The larger the diameter the larger the contact lens. The contacts diameter is measured in milimeters. A typical size for an average contact lens diameter might be 14.2 milimeters. While this size is calculated by the eye doctor during the exam it's also normal for many patients to require contacts of a similar diameter and in fact many popular cosmetic contacts only come in a single diameter. It's sort of the one size fits all approach and if you don't fit in that size then you don't order those contacts. It's also possible, not necessarily recommended, for the same person to wear contacts of different diameters. This is especially evident with Circle Lenses contacts which are normally very large in diameter so that they cover more of the iris and provide the illusion that the wearer has larger colored eye balls. Many circle lenses are available in only one size diameter. Note that they eye doctor should provide with the diameter that is most likely to be the best fit and as such the most comfortable contact lens. |
