The lens index symbolizes the level of compression of the material in the lens and affects the thickness and weight of the lens.
The higher the index, the thinner and lighter the lens.
A high index is important due to the comfort of the glasses and also for the aesthetics since thick lenses in the glasses will stand out and in addition the eyes of the glasses component will look large.
However a high index is only necessary in cases where the number is high, in cases where the standard number does not need to choose a high index because we will get the same result.
Our recommendation for indexing the number of lenses:
|1.56 The thickest lens.||0.25-\+ to 3.00-\+|
|1.6||3.25-\+ to 5.00-\+|
|1.67||5.25-\+ to 6.75-\+|
|1.74 The thinnest lens.||7.00- and up.|
From today you can order eyeglasses online, so how do you do that? First you need a prescription for glasses which will be photographed and attached during the ordering process, if you do not have one you must check to get the prescription. You can also check the existing prescription in your glasses with the help of the GlassesOn app and use it to make glasses with the same prescription as yours.
You can download the application here:
Prescription looks like this:
CYL-cylinder (there may be a prescription without a cylinder)
AXIS - Cylinder angle (only in case there is a cylinder)
PD - distance from the right eye to the left eye.
We will then select the appropriate lens index according to the following table:
|0.25-\+ to 3.00-\+||Index 1.56|
|3.25-\+ to 5.00-\+||Index 1.6|
|5.25-\+ to 6.75-\+||Index 1.67|
|7.00- and up.||Index 1.74|
Now all that remains is to select the frame, select the appropriate index in the product options, upload the photographed prescription on the item page (you can take a photo directly from your mobile), and place your order.
