1. Push Out The Lenses From the Inside Out. The easiest area is from the middle top part of the lens.
2. Start by putting the lens in the temporal or outer part of the frame first.
3. Gently push the nasal or inner part of the lens inside the bevel.
Apply a little pressure with your thumb to push the front of the lens, allowing it to snap right into place.
For Metal Frames:
1. Due to the lack of flexibility in metal frames, a screwdriver is needed to unscrew the side & remove the lens.
2. Begin by inserting the inner side of the lens into the frame & then the outer side of the lens.
3. Finally, use a screwdriver to tighten the frame and ensure a snug fit.
