puolikehyksisissä

Puolikehyksisissä is a Finnish term that translates to "semi-rimless" in English, primarily used in the context of eyewear. Semi-rimless glasses are characterized by a frame that only partially encloses the lens. Typically, the top half of the lens is held by a rim, while the bottom half is secured by a nylon fishing line or a similar thin filament. This construction provides a lighter feel and a more minimalist aesthetic compared to full-rimmed glasses.

The design of semi-rimless glasses offers several advantages. They are often lighter, which can increase comfort for extended wear. The partially exposed lens edges can also create a less obtrusive look, making them a popular choice for those who prefer a more subtle eyewear style or want to draw attention to their eyes rather than the frame. Furthermore, the construction can allow for a wider field of vision in some cases, as there is no full frame obstructing the peripheral view.

However, semi-rimless glasses can also have drawbacks. The exposed lower edge of the lens is more vulnerable to damage, such as chipping or cracking, compared to lenses fully protected by a rim. The nylon cord used to secure the lens can also wear out over time and may need to be replaced. Lens replacement in semi-rimless frames can sometimes be more complex and costly than in full-rimmed or rimless designs. Despite these considerations, semi-rimless glasses remain a widely chosen option for their distinctive style and comfortable wear.
