The durable Oakley Monster Dog sunglasses offer 100 per cent UV filtering. Just because you own one set of lenses doesn't mean you can't switch things up. Oakley offers a variety of lens colours for the Monster Dog. Whether you need to replace a scratched lens or you simply want to try out a new colour, you can replace the lens yourself. Go to Oakley's website to find the lens replacement you want before removing the old lens.
Hold the lens frame with both hands. Your thumbs should be on the back top frame, and your fingers should wrap around the front of the lens frame.
Push up on the top frame with your thumb.
With the lens frame pushed up, gently pop the lens out at the top with your other thumb.
Slide the new lens into the groove at the bottom of the frame. Once the lens is halfway in, push the top frame up as you move the rest of the lens into place.
Release the frame and allow the lens to snap into place. You may need to run your fingers around the frame to wiggle the lens correctly into position.
