About Montana Readers R20 R20B

A full-rim square frame sets the tone on the SmartBuy Readers R20, giving everyday reading glasses a clean, structured look that suits a wide range of faces. The Black/Blue colour pairing keeps it sharp without feeling severe, while clear lenses maintain a straightforward, no-fuss finish that works at home, in the office, or on the go. Made in plastic, this unisex design is easy to wear and simple to style, especially if you prefer a frame with defined lines rather than a softer round profile. The square shape is particularly flattering on round and oval face shapes, adding contrast and visual balance. With a classic full-rim build, the R20 keeps the lens area neatly framed for a dependable, familiar feel. SmartBuyGlasses supplies genuine SmartBuy Readers frames and backs them with a 2-year warranty, 100-day returns, and a Best Price Guarantee, plus free shipping on orders over $80. Please note this model is not prescription-compatible, so it’s intended as a ready-to-wear reader rather than a frame for custom RX lenses.

If you don’t wear glasses

You only need a ruler and a mirror. All measurements are in millimeters (mm).

Frame width Measure across your face from one side of your forehead to the other, just above your eyebrows. This helps ensure the frame fits comfortably without squeezing or slipping.
Bridge Width Measure the width of your nose at the narrowest point between your eyes. A proper bridge fit prevents pressure or sliding.
Temple Length Measure from the side of your face to just behind your ear, following the natural curve of your head. This ensures the arms of the glasses sit comfortably and securely.
