How to Change a Tifosi Lens

Tifosi makes sunglasses for sportsmen and super fans.

Tifosi is Italian slang for "super fan." Tifosi Optics designs sunglasses for professional and recreational tennis players, golfers, runners and bicyclists, and in March 2011 it was the best-selling sunglasses brand in bike and run specialty shops. The glasses are easily adjustable, and the lenses on many models are ventilated. Tifosi asserts the lenses are shatterproof, eliminate distortion, "give sharp peripheral vision, and offer 100 percent protection from harmful UVA/UVB rays, bugs, rocks, or whatever comes your way. Lens installation and removal," the company states, "is fast and easy."

Things You'll Need

• Replacement lenses

Instructions

1. Fully extend the sunglasses arms and hold the sunglasses face down with both hands.

2. Place your fingers on the front side of the frame and your thumbs on the back side

   of the frame while letting you thumbs rest on one lens. Work on one lens at a time.

3. Spread the frame apart with your fingers as you press down on the lens with your thumbs to release the lens. Repeat for the other lens.

4. Turn the sunglasses over so they are face up and put the replacement lenses within reach. Install one replacement lens at a time.

5. Place the replacement lens over the frame and align it with the open groove on the outside of the frame just in front of the arms.

6. Put your fingers on the back of the frame and hold the lens against the frame with your thumbs. Spread the frame with your fingers as you push the lens into the outer corner of the frame with your thumbs.

7. Press the inner and outer edges of the lens into the frame with your thumbs. Ensure the lens is seated in the frame by squeezing the perimeter of the frame. Repeat for the second replacement lens.
