It’s simple: to help you save money. Lenses with adhesive backing typically cost twice as much because of the extra time required to pre-laminate the adhesive. Even with the backing, you’ll still need to complete the second half lamination process yourself. So, why not do it all at once and save on costs? You can easily find high-quality double-sided adhesive on Amazon by searching for "double-sided adhesive sheet 3M."
