Whether you already have a prescription or not, it does not matter. Easyviz will take care of all your needs. Thanks to its network of highly qualified opticians, we can provide you with all the services required by your special needs.
What is a prescription?
The first step to every spectacles purchase is the Eye Exam. An eye exam will measure the requirements the optician will have to follow in order to choose the correct lenses for your sight. An eye exam takes usually around 30-40 minutes and after going through several exams your optician will give you a prescription similar to this one.
A more complete exam exists also and is also recommended for difficult sights.
Recommendation: If you are using contact lens don't forget to take them of before your graduation test. We even recommend you to take them of between 12 and 14 hours before, to be sure that the result will be 100% correct.
I already have a prescription, what do I do?
We cannot accept legally prescriptions older than 2 years. However, your sight might have changed since your last revision. This is why we strongly advise our customers to have a prescription made every 6 months or before a spectacle purchase. If you know that your sight has not changed then you can enter in your profile your prescription not forgetting the name and collegial number of the optician or ophthalmologist who gave it to you (if not we will not be able to accept it).
I want to have a prescription made or renew it.
Several options are open to you.
You can go into your nearest optician shop and ask for a prescription. They might or might not ask for a payment for this service.
You can also visit an optician who has an agreement with the social security and provides in quite all provinces a free prescription service. Please contact your local social security center to obtain the procedure to follow.
Or you can use one of our highly trained opticians or ophthalmologist in order to obtain an Easyviz certified®, fully qualified prescription.
In order to do this, it is very simple. When you order your frames and lenses, you just select the optional Eye Exam service and the nearest Easyviz qualified optician®. We should insist throughout the web site on the quality of our opticians and that we select the “top-cream of the sector”. Add here the scan of a typical prescription (different for each country) with annotations circling the important data. In a country like France for instance, on the ophthalmologist can prescribe while in Spain, both can. After payment, you will receive a voucher to give to the optician who will be automatically aware of your visit. When the eye exam is done, our optician will enter your prescription in our files in order for the mounting to take place. You might want to come back later for an optional individualized adaptation.
How do I read a prescription?
A prescription uses several parameters to describe your sight at the time the eye exam is taken. It uses numbers and symbols of the type and strength of lens you need in order to obtain a good vision. A prescription contains the following parameters:
Sphere (SPH)
This describes the amount and type of prescription you need. If you are long sighted (myopia) your prescription will be preceded by a - sign. If you are short sighted (astigmatism) your prescription will be preceded by a + sign. The higher the number, the stronger the prescription required.
This parameter is needed in all prescriptions.
Cylinder (CYL)
The cylinder is only necessary if you have an astigmatism (or visual distortion). This is quite common and is caused by an irregular shaped cornea (link to >>Spectacles 101>>Vision 101). This measurement is also preceded by a + or – sign.
Axis
This axis describes the direction of the astigmatism. Axis will be shown only if the Cylinder is filled. This is measured in degrees.
Prism
Correction required to balance the eyes.
Near addition (NEAR ADD)
This describes the amount of additional correction necessary to focus at near distance (e.g. reading). Usually, this requires you to wear different spectacles in addition to your normal ones. You can also choose varifocal lenses which will work for both sights.
Intermediate addition (INT ADD)
Here is described the amount of additional correction required to focus at intermediate distances (e.g. working at a computer). In this case you are advised to wear varifocal lenses.
PD (Pupillary Distance)
This one measures the distance between the centre of the pupil in one eye to the centre of the pupil in the other. This measurement is essential to position the center of the lenses within their respective frame. You can ask for this parameter when you have your eye examination. If it is not on your prescription, don’t worry as most people conform to an average PD of 63mm. If you do not have this information an average PD will be selected for you.
This parameter is advised for all prescriptions.
