Contact Lens Prescription
We can only process orders for contact lenses if we receive a copy of your recent Contact Lens Specification. (Please do not confuse it with your spectacle prescription).
It must show the following information:
- Date of your last eye examination. This should be no more than 12 months old. (This is to ensure that you have had your eyesight checked recently).
- The brand and type of lenses prescribed.
- The fitting and power details.
- Your optician's name and address
Please Fax your specification to us on: +44 (0)20 8654 3284
If you have had a recent eye test, but do not have your contact lens specification to hand we suggest you contact your optician or provide us with details of your optician, and we shall obtain your specification for you.
Understanding your Contact Lens Prescription
This is what a typical Contact Lens prescription looks like :
Eye : B.C/Dia/Power
Right : 8.60 / 14.00 / -2.50
Left : 8.60 / 14.00 / -3.50
The numbers above provide the base curve (BC), diameter (DIA) and power, of your lenses; if you wear Toric lenses, it will also contain the cylinder (CYL) and axis. If you are wearing bifocal contact lenses there will be an additional power correction ADD. If you are wearing coloured contact lenses the colour is also specified, this does not affect the prescription of the contact lens.
- The Power is the strength of the contact lens. It is a number between -20 and +20. for Example -3.50
- The Base Curve (BC) is the shape of the contact lens as recommended by you optician following fitting
- The Diameter (DIA) is the size of the contact lens as recommended by you optician following fitting
- The Cylinder (CYL) is only required for Toric lenses. It is the strength of your astigmatism. It is a number between -4.00 and +4.00
- The Axis is only required for Toric lenses. It is the location of your astigmatism. It is a number between 0 and 180
- The Addpower is only required for bifocal contact lenses. It is the reading strength of the lenses. It is a number between +1.00 and +2.50
All of this information can be found on your prescription as well as on your lens packaging. Below is an example of one:
