Here are the answers to the most common questions:


  • How do I check the UV protection of my model? 

A sticker certifying the UV protection of our lenses must be present on the left optic of each of the frames. 


  • What does the category (1,2,3,4) of a frame correspond to?
Categories 1, 2, 3 or 4 classify glasses according to the "amount" of sunlight they filter (the category is directly correlated with the tint of the glass).
  1. Category 1 filters 20% to 57% of solar light
  2. A category 2 filters from 58% to 82% of sunlight 
  3. A category 3 filters 83% to 92% of the solar luminosity 
  4. Category 4 filters up to 97% of sunlight (prohibited for driving)

  • How to check the category of my model? 

As our models were initially marketed in Japan, their marking is subject to the regulations in force on Japanese territory. However, all the required information is present and in particular a clear indication making it easy to find the lens category of each frame.  

To check it, all you have to do is note the percentage printed after the product reference inside the left temple of the frame. This corresponds to the "quantity" of solar luminosity unfiltered by the glasses which then allows you, by comparing it to the list detailed above, to find the corresponding category in the blink of an eye.

Take the example of the model MIKI N; TY2854-1S 10% -> this 10% corresponds to the "quantity" of solar luminosity unfiltered by this model -> which means that the MIKI N glasses filter 90% of the solar luminosity -> So MIKI N belongs to a category 3.
