Practical active solution - ESS CDI RX Inserts 740-0312 w/ RX Prescription for CDI Sunglasses

Initially got a defective insert. Cannot tag the cause, but the Optics Planet team took great corrective action and I am now enjoying the modular aspect of the product. The ESS CDI are really a boon for active people that need safety an RX.
I have yet to test them in wet environments. I expect this type of product to annoy the churn of frames in the business since you can change the lenses (relatively easily) and can even keep spares.
Pros: You can change the prescription and keep the frames, moderate good looks
Cons: The inserts need to be done right in the lab, the lens has to be well seated in the insert
