Polycarbonate lenses are lightweight, impact-resistant thermoplastic eyeglass lenses that offer inherent UV protection. Made from a durable polymer, they are produced by heating and molding polycarbonate pellets, a process that results in a shatterproof lens ideal for safety glasses, sports eyewear, and children's glasses.

Transition lenses are photochromic lenses that automatically darken when exposed to UV light and return to a clear state when indoors, effectively combining prescription glasses and sunglasses into one pair. This adaptive quality helps to shield your eyes from harmful UV rays, reduces squinting, and provides optimal vision in changing light conditions

Bifocal and trifocal lenses are types of multifocal lenses that contain multiple prescriptions in a single lens to correct vision at different distances. They are most commonly prescribed for people with presbyopia, a condition that makes it difficult to focus on close objects as you age.  Fun fact - the image above is a pair of bifocal lenses designed and created by Benjamin Franklin.
