Gravity II Medium TR-90 Lightweight and Tough





We designed the Gravity model to be functional multi-focus reading glasses for mechanics. There are a few "car guys" at Sightline and we were tired of having our readers fall off while we were in odd positions working on our cars. The ratchet action temple holds the glasses in place no matter your head position.
These reading glasses are also remarkably strong. Fear not if you drop them, or toss them on your work bench. They are made of TR-90 "the titanium of plastic". TR90 is a Swiss-made thermoplastic material that is incredibly durable, flexible, and lightweight. Because the material is pliable, they are far less likely to break or bend from impact. Finally, and most remarkable of all, TR90 glasses are supremely lightweight!
SightLine Multifocal Gravity II is a modern take on traditional cable temples like these.
