Which Type Of Lenses Do I Need For My Prescription?
Prescription without value in add/near column
As you can see on the prescription above there is no value in the add/near section. This means that the wearer doesn't require any additional help for focusing at reading distances. This is generally those under 40 years of age who haven't yet experienced presbyopia (loss of ability to focus on nearby objects).
On standard prescriptions such as these you will have a SPH, CYL and AXIS value, although sometimes they may have a zero or dash. If you are unsure which lenses you require, simply contact us for free advice. Although it's rarely given, you may also see a P.D measurement (PUPIL DISTANCE in mm).

Prescription with values in add/near column
On this example of a prescription you can see there is a value in the add/near section. This means that the wearer will require additional power in the lens to focus at reading distances. This is generally applicable to those who are 40+ years of age and are experiencing a gradual loss of ability to focus on close objects such as reading a book.
The add power is simply added to the general distance prescription to give you your reading prescription. Sometimes prescriptions are written with both distance and reading written in full for both your right and left eye (EXAMPLE BELOW). If you're unsure contact us for FREE advice and we'll talk you through your options.
EXAMPLE RIGHT EYE
DIST -2.00 +0.50 90
