We separate our frame sizes into three categories: small, medium, and large/xl. Each pair is measured across the widest part of a lens, which is called the lens diameter or Eye Size. Don't know your eye size? Follow these 3 steps! 

1. Find Your Current Frame Size

    • Look on the inside of your everyday glasses

    • Your glasses are marked with 3 numbers to indicate

      • Lens Diameter [A]

      • Bridge Width [DBL]

      • Temple Length [TL]

    *most commonly found on the inside of the temples (as shown), but may be displayed elsewhere on the frame


    2. Size Up! Rec Specs Has More Frame Curvature

    • Add 2-3mm to your current frame's Lens Diameter to find your Rec Specs size
    • e.g. 54 + 3 = ~57mm


    3. Shop for Rec Specs - Filter by Eye Size or Fit






    55mm +
