Tutorial

How to change the lenses on your glasses?

  1. Prepare your glasses: Wash your hands and place the glasses on a clean, soft surface to avoid scratches.
  2. Loosen the frame screw: Use a precision screwdriver to carefully loosen the screw holding the lens. Keep the screw in a safe place to avoid losing it.
  3. Remove the old lenses: Once the screw is loosened, gently slide out the lens, avoiding excessive force to prevent damaging the frame.
  4. Align the new lenses: Ensure the new lenses match the curvature and shape of the frame.
  5. Insert the new lenses: Carefully place the lens into the frame and reinsert the screw, tightening it gently to secure the lens without over-tightening.
  6. Check and clean: Ensure the lenses are properly fitted and clean the surface with a microfiber cloth.

It’s that easy! Enjoy your refreshed glasses with new lenses.
