Can I use my contact lenses prescription to order glasses?
No, although your prescription for contact lenses and prescription glasses may look the same, they usually differ. Check your eyesight for the use of glasses and for the use of contact lenses.
If you have any doubts, you can send us your prescription by email and we will study what prescription to put on your glasses or contact lenses.
What is interpupillary distance (PD) and how do I obtain it?
For your glasses to have an optimal vision, the assembly of the lenses must be adjusted to the distance between the user's eyes and the center of each lens must coincide with the center of the user's pupil.
To achieve this we need your "interpupillary distance" (PD) or distance between the pupils of your eyes.
If you don't know the interpupillary distance, we assemble your glasses using a standard interpupillary distance.
The interpupillary distance can have different names, such as "centers" or "distance from centers," but they mean the same thing.
Using standard interpupillary distance works well for most people, although it is true that some people with high prescription parameteres whose interpupillary distance varies greatly from the average may have problems using a standard PD. In these cases, the glasses will not harm the eyes, but they can cause discomfort.
In any case, you can measure the interpupillary distance yourself. The best way is to have someone help you. Look at a fixed point on the horizon, while the other person measures the distance between the pupils in millimeters with a ruler. If you want to be very precise, measure the distance from the left edge of the left pupil to the left edge of the right pupil.
What does each parameter of my prescription mean?
If you want to know what each of the parameters we need to manufacture your lenses means, you can make use of our "Help for Prescription", which you will find at the end of the section.
I don't understand my prescription
You can send us your prescription to our email address or scan it and send it by mail to firstname.lastname@example.org and we will try to understand it together.
I don't know how to fill in the form with my data
It is simply a matter of putting the information of your prescription in our form. We give you an example. Let's imagine your prescription looks like this:
In this case, you would have to fill in the form as follows:
If your prescription has more data or it is still not clear how you should complete the form, you can contact us and we will help you place the order.
In my prescription there is a parameter called "Addition" but I don't see it in your form. Isn't this parameter necessary?
The "Addition" or "ADD" parameter is used only for progressive or bifocal lenses. At the moment we do not sell bifocal or progressive lenses due to the difficulty of their online adaptation.
We recommend acquiring this type of lens at your trusted optician, where they can make a correct adaptation.
What if I have entered my data wrong?
Immediately call us or send an email, because we process orders quickly. We can only make changes to your order prior to shipment. Check your prescription and if you need it, ask our customer service team to confirm that we have received the data correctly.
What should I do if when I receive my prescription glasses or sunglasses I need to adjust the frames?
If you need a minor adjustment, any optician can do it for you for free or for a very small amount. If you continue to have problems with your glasses, please call us or send an email explaining the problem and we will try to give you the best solution.
