Rimless, flat lenses are a big sunglasses trend for 2019, and these get a lot of comments. Fun fact I did not know until we put a few similar styles into development -- the lens material you need to use for rimless sunglasses is more expensive than the lens material you use for rim inset lenses, because it has to be strong enough to sustain the drill holes so that the lenses can be anchored to the frame. I love learning why different styles cost different amounts and what drives the cost of the finished goods -- and here's an instance in which the retail price justifiably has to go up because it requires more expensive components.
