The Izipizi #D Reading Glasses pair a rounded pantos frame with flex hinges that move with the shape of a face instead of pressing against it. The arms flex to fit snugly at the temples without pinching, so the glasses go on and off all day without loosening over time. Magnifying lenses in a +2 diopter correct near vision for reading, lightweight and scratch-resistant enough for daily use. What Our Gearhead(R) Experts Are Saying:"I take these on and off all day, in my bag and back on my face, and the hinges still snap back to shape instead of drooping open. The frame stays snug on my nose without pinching after a full day of reading on and off."
