Optical prescription insert for the Nashbar Oculus cycling sunglasses. This is a "blank insert". We'll ship it to you, then you drop it off with your optometrist and they'll grind it to your prescription. Once you have them, they clip right inside your shiny new Oculus sunglasses, so you can see clearly no matter what the lighting conditions are.
Insert lets you turn a pair of Nashbar Oculus glasses into the right glasses for you
"Blank" insert can be custom ground to your specific prescription
These work just fine in my Nashbar sunglasses. Because you can get the lenses ground and not need any coatings the prescription lenses for the insert were cheap. In fact with the cost of ground lenses, insert and the Nashbar glasses they are the least expensive prescription sunglasses I own. Again since the glasses themselves are so inexpensive, I bought a second pair in case something were to happen to the first pair. As an added bonus I keep the second pair loaded with a different color of the lenses as it is actually easier and quicker to change the adaptor from one frame to the other than change out the lenses in a frame.
Was this a gift?:
Bottom Line Yes, I would recommend this to a friend
