Prescriptions Explained

Once you have booked in and had one of your eye examinations, one of our optometrists at our London opticians will tell you whether you need glasses or if your prescription has changed. They will also give you a copy of your prescription. This features the precise measurements for the kind of prescription lenses you will need.

We understand that being told about your prescription can sometimes be quite confusing which is why we like to take the time to explain to all of our clients what the prescription means and what the next step is.

If you take a look at the prescription, you may be a bit perplexed to say the least!

There are six parts: ADD, BASE, PRISM, AXIS, SPH and CYL.

ADD may have a number in the box, especially if you are over the age of 45. This indicates you have different prescriptions for reading and distance.

BASE tells the lab where to put the prism in your glasses.

PRISM indicates there is an imbalance between your eyes.

AXIS is the direction of the astigmatism, measured in degrees.

CYL (cylinder) is the amount of astigmatism.

Finally, SPH (sphere) indicates that you are long-sighted.
