4. Lens Replacement Procedure
Follow these steps to safely replace the lenses in your VISOFO MS20 Video Sunglasses:
- Prepare the Sunglasses: Hold the sunglasses firmly with one hand. Ensure the arms are folded or positioned to allow clear access to the lenses.
- Remove Existing Lenses:
- Gently push the lens from the inside of the frame outwards, starting from the corner closest to the nose bridge.
- Apply steady, even pressure until the lens detaches from the frame.
- Repeat for the other lens.
- Store the removed lenses in a safe place if you intend to reuse them.
- Install New Lenses:
- Align the new clear lens with the frame.
- Insert one edge of the lens into the frame groove, typically starting from the outer edge or the side furthest from the nose bridge.
- Carefully press the rest of the lens into the frame, working your way around the edges until it snaps securely into place. You should hear a subtle click or feel it seat firmly.
- Ensure the lens is flush with the frame and does not wobble.
- Repeat for the second clear lens.
- Final Check: Inspect both lenses to ensure they are correctly installed and secure. Gently wipe the lenses with a microfiber cloth to remove any fingerprints.

- Storage: When not in use, store your VISOFO MS20 Video Sunglasses in their protective case to prevent scratches and damage.
