Make Your Own Prescription Swimming Goggles

Step 5 Sanding the Surfaces in Preperation for Gluing

The edges of the prescription glass lenses that overlap the goggle frames need to be sanded for better glue adhesion, if you are using plastic lenses.

Using the fine grit sandpaper, lightly sand around the edge of the lenses (on the inside surface) where they will be glued to the goggles.

You should also lightly sand/roughen the goggle frames to which the sanded edges of the lenses will touch. This will help the glue adhere to the goggles.
