Hello!
We offer Single Vision lenses Sphere (SPH) correction for nearsightedness or farsightedness glasses.
Prescription range limits: The sum of the negative values for SPH and CYL should not go over -8.00 and the sum of the positive values for SPH and CYL should not go over +6.00.
The easy steps are the following:
1. Make sure you have an updated ophthalmological prescription.
2. Once you place your order with the prescription, you will receive your "Thank You" confirmation email with the prescription form.
3. Make sure you write down the exact prescription that your doctor gave you, as this will be what our lab will assemble :)
> Information we will ask you in our prescription form:
1. Your myopia for both eyes. In your prescription should be named as sphere, SPH or ESF. If you just need simple reading glasses (+1, +1,5, +2, etc.), you would only have to fulfill this parameter.
2. Your astigmatism for both eyes. Astigmatism is detailed by two concepts, Cylinder and Axis. Cylinder can be named as CYL.
3. Your pupillary distance. To properly center your prescription in your chosen frame we need the distance between your pupils or the distance between your pupils to your nose. If you don't have it you can measure it by yourself, here you have a picture of what is the Pupillary Distance: https://www.eyeweargenius.com/wp-content/uploads/2018/11/Dual_Pupillary_Distance.jpg
With all this information you will have very soon your new prescription glasses!
