Do rimless glasses have hidden lines?

Rimless glasses are a popular kind of glasses, in which the lenses are directly mounted on the bridge of the nose and/or the temples. This style is divided into two sub-types: three-piece glasses consist of a lens mounted on the bridge of the nose and two independent temples, while the frames (also known as cortlands) have a supporting arch to connect the temples to them and provide them with extra stability.

Frameless glasses were a popular style from1880s to1960s, and became popular again in the second half of 20th century and at the beginning of 2nd1century. From 1993 to 20 1 1 died, Steve Jobs, the founder and former CEO of Apple, wore round rimless glasses for 18 years.

Despite these changes, their glasses have a unique style and have never been completely out of fashion. After many years, they left an acceptable and more fashionable design choice.

method of erection

The rimless spectacle lens is fixed (or installed) in two holes of the lens by a series of screws or hollow plastic double rivets (called "bushings" or "compression plugs"). When using the sleeve, there are barbed metal pins on the temples and the bridge of the nose, which can be locked into the sleeve to form a pressure seal and fix the lens in place. Although they are more beautiful, the bushing method is more fragile than the screw-nut method, and it is more difficult for laymen to repair themselves if they are loose or broken. However, the design of the frameless mounting base based on the bushing allows the pin to be pulled out of the lens without being damaged, thus reducing the maintenance cost and duration.
