PWR

 

 

 

 

 

 

 

These numbers are usually the first set of numbers listed next to the OD and OS rows or columns. They indicate the strength of correction needed for that particular eye or, if OU is listed, both eyes.

  • For example, if the field under OD reads -3.50 D, this indicates that you have 3.5 diopters of nearsightedness in your right eye. If the field under OD reads +2.00, this indicates that you have 2.00 diopters of farsightedness in the right eye.

It is common for the correction to differ between the right and left eyes. If you find the term PL, which stands for Plano, it means the number is 0 and no correction is needed for that particular eye.

 

Understand the base curve (BC).

 

BC

 

 

 

 

 

 

 

This term describes how the curvature on the inside of the lens should be. This is measured so the lens fits perfectly against your eye and fits the shape of your cornea. Unlike most of the other numbers, this number is measured in millimeters.

This number typically ranges from 8 to 10. The lower the number in this column or row, the steeper your cornea is.

DIA

 

 

 

 

 

 

 

Find the diameter (DIA). The diameter is the measurement of a straight line through the center of the contact lens. It lets the maker of your contact lenses know how big around you need your contacts to be to fit your eye. Like the BC, the DIA is also measured in millimeters.

This is a very important measurement. If it is off, your lenses can cause irritation or abrasions on your eyes.[8]

 

Name & expiry date:

 

Your prescription should also contain the name of your contact lens e.g. Acuvue Oasys and an expiry date, which is usually a year from the date of your check-up.

Below is an example of the prescription listed on the side of the box for 1-Day Acuvue Moist for Astigmatism.

 

SCRIPT

 

 

 

 

 

 

Please be aware that a contact lens prescription is different to a glasses prescription, so you cannot use one for the other.

What does each prescription figure mean?

Base Curve (BC):

The base curve determines what type of fit is required for the lens to meet the curve of your eye; this is usually written in millimetres or sometimes with the words: flat, median or steep.

Diameter (DIA):

The diameter of the contact lens is also written in millimetres and determines the width that best fits your eye.

Power/Sphere (PWR/SPH):

This figure shows whether you are long or short-sighted and how much correction your eyes require. If you are long-sighted your figure will begin with a + (plus sign) and if you are short-sighted it will begin with a – (minus sign). This will be followed by a number that goes up from 0 in measures of 0.25 dioptres, the higher the number the stronger the visual correction needed (this value can be displayed on the box as “PWR” or “D”).

Prescription Figures for Astigmatism

The below figures are only displayed on contact lens prescriptions where there is a need for astigmatism correction.

Cylinder (CYL):

The cylinder will always been a minus number that increases in measures of 0.25. Much like the power/sphere figure that is shown on all standard prescriptions, the cylinder denotes the extra visual requirements needed for astigmatism and how severe the astigmatism is.

Axis (AX):

Astigmatism is caused by the irregular curvature of the eye; the axis is a figure which determines the angle of the correction needed in order to see clearly. The Axis is always a number between 0 and 180 degrees.

Prescription Figures for Presbyopia

The below figures are only displayed on contact lens prescriptions where there is a need for presbyopia/multifocal correction.

Addition (ADD):

If you suffer from presbyopia it affects your near vision, the Addition figure determines what level of correction you need to be able to see clearly at a close distance. This is a number between 0.50 and 3.00, some contact lens brands refer to this as a high, medium or low.

Dominant: If you wear multifocals or bifocals your lens correction is determined by a dominant and non-dominant eye, this is the dominant figure usually marked with a “D” and “N” to express which eye is which.
