This is a sample of a eyeglasses prescription.

O.D. - Denotes Right eye. This is sometimes written as R.
O.S. - Denotes Left eye. This is sometimes written as L.

Sphere (SPH)

Indicates how near-sighted or far-sighted you are. It's measured in diopter.
+ indicates far-sighted vision
- indicates near-sighted vision
"Plano" or "Pl" means 0.00.

 

Cylinder (CYL) 

Cylinder measures in diopters the degree of astigmatism that you have.
Some prescriptions are written in minus(-) and some are written in plus(+). Prescription provided by your optometriest usually have a (-) cylinder.

AXIS
The Axis is a number anywhere between 0 and 180 degrees. It reveals the orientation of the astigmatism.

Near Add
Near addition. Bifocal prescriptions, which correct both nearsightedness and farsightedness, usually have "add" to indicate plus power for near distance. If there is only one ADD power on your prescription for bifocals, this means that the same ADD power is used for both eyes.

If you cannot read your prescription you should verify it with your optometrist. If you wish our customer service team to look at it you can fax your prescription to 03 -95023518 along with your optometrist’s contact phone number and your email address . Our customer service team will enter the prescription for you. You will be notified by email once your prescription is ready.

The CYL and AXIS are to correct astigmatism so if you don't have astigmatism you may not have a CYL or AXIS value on your prescription.

 

PD is the distance between the centre of two pupils when your eyes are looking at a distance object in the front that are 60 centimetres away or beyond. It is measured in millimetres (mm).

This measurement is used for fitting prescription lenses.

You can get your PD from your Optometrist.  The average PD is 60mm for women and 64mm for men.

   

Remeber to ask your optometrist to measure the PD for you next time when you visit the optometrist. Meanwhile, you can have your PD measured with a ruler and the help of a friend by following this instruction:

1. Put the millimetre ruler on the bridge of your nose.
2. Ask someone to stand approximately 60 centimetres away from you and measure the distance between the centres of your pupils (the black circle in your eyes) with your eyes looking at a distance object in the front.


3. You can measure pupillary distance yourself by using a mirror. You will stand at least 30 centimetres away from the mirror and measure the distance between your pupils with your eyes looking at yourself in the mirror.

We recommend you always ask your optometrist to measure the PD for you. Only measure the PD yourself as a last resort. It is important to get your PD from your optometrist if your prescription has high power or if you are going to order progressive or bifocal lenses.

Sometimes, your prescription would have two numbers for PD, for example "61/58". The two numbers are long distance PD and short distance PD. The PD mentioned on our web site refers to long distance PD, i.e. the PD when you are looking at distance objects that are 60cms away or beyond. In this example, the distance pd is 61mm. Short distance pd is the distance between the centre of two pupils when you are looking at a object that is 35cms away from your eyes, for example reading a book. In this example, the short distance PD is 58mm.

Please enter the large number, in this example 61, for the PD when asked on our web site. Then in the additional note field on the prescription screen, please enter both numbers as, for example "PD 61/58".

If you enter you details incorrectly then you need to contact our customer service immediately so that we can change the prescription before the frame is sent to the lab for fitting. It is important that you do this since lenses being cut for fitting cannot be refunded. However, the replacement of lenses can be made at your own cost.

 

No. Contact lens prescription can only be used for purchasing contact lens. You will need a prescription for eyeglasses in order to purchase eyeglasses or prescription sunglasses.
