Why choose a eyewear model with prescription (RX) insert instead of having the prescription in the outer lens?
If you need prescription lenses, choosing a Wiley X model with an RX insert will give you the following advantages compared to models, where the prescription is built directly into the frame (full frame design).

• Easy and cheaper to replace an outer lens which has no prescription.
• Up to 5 different front lens color options – allowing you to adjust to any given light condition.
• Everyone can use the eyewear without the insert.
• Still certified as safety eyewear.
• Inserts match different models (see below).

The PTX insert can be used in the following models: Saber Advanced, WX Vapor, WX Rogue, Nerve and Spear.
