Tralyx / Cutline RX Clip
The Tralyx and Cutline RX clip is a sports prescription solution for athletes requiring shield type lenses and RX optical prescription clips.
Essentially you'll be looking through 2 lenses with this RX design. The RX clip which will host your prescription then the cutter sunglass lens.
Normal course of action with purchasing the Tralyx/Cutline RX clip is that you will take both the RX clip and your sunglasses to your local optometrist and get them to insert your prescription into the clip. This is generally done through an optical lab and could take 7-10 days depending who they use.
Powers can go up and exceed -5.00 combined power but again this depends on the script and who the lab is along with the lens material they use.
