puolikehyksinen

Puolikehyksinen refers to a type of eyewear where the frame only surrounds the top or bottom half of the lens. This design is often called a "semi-rimless" or "nylor" frame. The other half of the lens is typically held in place by a thin nylon cord that runs through a groove in the edge of the lens. This construction offers a lighter feel and a less obtrusive appearance compared to full-rimmed glasses.

The aesthetic of puolikehyksinen glasses is often perceived as more minimalist and sophisticated. They can draw attention to the wearer's eyes without the visual weight of a complete frame. This style is popular for both prescription and sunglasses. The construction can offer a degree of flexibility, and the nylon cord can sometimes be replaced if it wears out. However, the exposed edge of the lens may be more susceptible to chipping or damage compared to lenses fully enclosed by a frame.

The term puolikehyksinen is Finnish and directly translates to "half-framed." It is a descriptive term that accurately reflects the optical design. The choice between puolikehyksinen and other frame styles often depends on personal preference, facial features, and the desired aesthetic.
