Sightline 3001 Narrow Fit Budget Progressive Readers

SightLine 3001 is with a playful color palette will look great while giving you great vision.  Narrow fit with a spring hinge for comfort. OK so why so cheap?  This frame is not like the other Sightline frames.  The spring hinge is plastic and therefore the longevity is very limited.  This frame is not suitable for optical eyeglasses - these a Walmart quality.  Peepers progressive uses a similar construction on their progressive readers - but they charge $$$.  All other Sightline frames are suitable for prescription eyewear - which is good as you will wear these longer because they are so comfortable to use.  If you wear narrow frames, and want to try progressives, this is a great choice.  Act fast as these will not be replenished - too many warranty claims for broken hinges.
