Prescriptions follow a standard format which will look something like this, they can be written or printed
Every prescription will have a right and left section for the correction of your vision within the following boxes:
“SPH” (sphere) The correction for long or short sightedness
“CYL” (cylindrical). The correction for an Astigmatism
“AXIS” This is what the cyl has to be set at
DISTANCE Can be either + or –
NEAR Will always HAVE A + VALUE
SPH (sphere) will have a + or – power in 0.25 steps. EG, -0.25, -0.50, or +0.25, +0.50 etc.
CYL (cylinderl) may have a + or – power in 0.25 steps. EG, -0.25, -0.50, or +0.25, +0.50 etc.
Axis a value from 0 to 180, however, only when there is a CYL value.
Should you need reading glasses an add or addition will be included on your prescription. We will convert this information into your corrective reading prescription. This add will always be a “+” value and we will add this value to your distance prescription to provide your reading glasses.
The above prescription looks like this when entered correctly on to our web site.
The PD section above (use PD Help) is the distance between your pupils in millimeters. At the moment an optician is also not required to give you this as part of your eye test, however, there may be a small charge for this service we recommend you have your PD measured by the optician If you do not supply a PD, an average PD based on your order information such as the size of frame, your gender and age will be used. If you would like to measure your own PD get a friend to help you, focus on a fixed point in the distance whilst your friend measures the distance between the centre of one pupil to the centre of the other in millimeters. (use PD Help)
