Z-Blue lenses filter the most problematic wavelengths from flashing and/or repeating lights and patterns. Unleash your lively and active side with Wrap TheraSpecs. This sporty style features a matte black finish as well as large lenses to maximize protection from the front and a wraparound shape that covers you from the top and sides. Constructed of ultra-lightweight, flexible nylon, it also helps reduce pressure on your face and head. TheraSpecs lenses were developed based on an extensive review of existing peer-reviewed research on lighting and the filtering of specific wavelengths. They are frequently recommended by neurologists, physical and occupational therapists, and other sensory sensitivity specialists for their light-sensitive patients. Premium anti-scratch, anti-smudge, and anti-reflective coatings, as well as 100% UVA/UVB protection. Wrap TheraSpecs come with a case and a microfibre cleaning cloth. The glasses are in near new condition. The microfibre cloth is unused. These glasses were a gift but I only used them about 3 times. These retail for over NZ $200.
