The Clic Sonoma is our first topless Clic magnetic reading glass. It's designed to allow for unobstructed over-the-top vision while being worn. The headband is slightly deeper to allow women with longer hair to be able to use the reader with their hair down and it is slightly wider to accommodate men with wider than average head sizes too. This really is the perfect reader for everyone. Available in a handsome blonde tortoise color with adjustable length temples. Available in strengths +1.25 to +3.0 and the measurements are: Front: 135mm wide, Lens: 32mm tall, and Front to Back: 194mm
