Review on Bifocal Sunglasses by Style Eyes: A Perfect Blend of Style and Vision by Ivan Carson

Suitable for my medium to large head, clarity is good. Due to my age, I use reading glasses at work and have found it difficult to read the fine print on some dashboards when driving without reading glasses. The bifocal lenses are set low enough not to obstruct your view of the road, but they're easy to use for a quick glance at the dashboard. Since this distance is a bit longer than usual for reading glasses, I just buy one power less than usual and they work great while driving.
