(This information can also be found of the contact lens box).
Here is the information a prescription should contain:
- OD = right eye
- OS = left eye
- BC / Radius (curve of the contact lens)
- Brand name (for example Dailies)
- BC / Base Curve (a number between 8.0 and 10.0)
- DIA / Diameter(a number between 13.0 and 15.0)
- Power / Sphere / Rx (a number between -20.00 and +20.00)
- Cyl. / ZYL / Zylinder: (a number between -20.00 and +20.00)
For astigmatic patients, we also need:
- Cylinder (a number between -4.00 and +4.00)
- Axis (a number between 0 and 180)
Cylinder and Axis are usually separated by × and read as "times"
A contact lens prescription is not the same as an eyeglass prescription.
In addition to lens power, a contact lens prescription contains other information related to the size of the lens.
The power of the contact lenses is generally not the same power as in your eyeglass prescription. This is because the contact lens is located on the surface of your eye, while your eyeglasses are located about 10-14 mm in front of your eye.

Should I have regular eye exams even if my eyes has not changed?
You should follow your eye care professional's advice, and have regular exams of your eyes. Contact lenses may cause damage to your eyes without necessarily causing any obvious symptoms.
