At every show we attend, someone inevitably asks about readers. So, we decided to offer high-quality readers made with TR90 frames, a rubberlike material originally developed for the military. TR90 is an excellent choice for eyewear, being incredibly strong, flexible, and lightweight.
These readers are available in seven strengths: +1.00, +1.50, +2.00, +2.50, +3.00, +3.50, and +4.00. They also come with a plastic carrying case.
