SafeVision.com exclusively uses HOYA prescription lenses in our safety glasses. HOYA is a renowned leader in optical technology, known for their precision craftsmanship and commitment to quality. These lenses are specifically designed to meet safety standards and provide optimal visual clarity. We offer Polycarbonate and Phoenix (aka Trivex) lens materials as they’re ideal for impact/shatter resistance vs. plastic or glass. Phoenix (aka Trivex) is highly recommended as it is more chemically resistant than polycarbonate.
