At home, school, the workplace, or the cinema—presentations of 3D content are increasingly integrating into our lives. Currently, the most widely available 3D systems require eyewear for viewing the 3D content; as a result, personal 3D eyewear products have become available to consumers. Various materials have been used to make circular polarized 3D lenses. These materials are selected based on performance and cost/price-point requirements. Considering the limited knowledge of ophthalmic lens design and materials amongst the general public, selecting over-the-counter 3D eyewear with effective performance and optical qualities is potentially a difficult task. Ineffective products could result in visual discomfort, as well as, perpetuate a negative public opinion of 3d media. Using existing standards and newly developed testing, the Vision Performance Institute (VPI) has established criteria for effective, durable, and safe 3D eyewear. The VPI 3D Eyewear Certification Program exists to maintain a quality standard in 3D vision-related eyewear, and to protect consumers from ineffective, potentially harmful products.
