Aqua Optics Dive Mask Magnifying Lens Glue is the easy to use glue to reach for when you need to affix magnifying lenses to a dive mask. It's better to over-apply glue than to under-apply it, and excess glue is easily removed using cold water and a soft bristle tooth brush. Do NOT use hot water, as this will loosen the cured glue under the glass lens.
