Rimless eyeglasses
Encyclopedia
Rimless eyeglasses, are a type of eyeglasses in which the lenses are mounted directly to the bridge and/or temples by way of a series of screws, rather than the lenses being secured inside of frames which encircle the lens. The style is divided into two subtypes: three piece glasses are composed of lenses mounted to a bridge and two separate temple arms, while rimways (also called cortlands) feature a supporting arch that connects the temples to the bridge and provides extra stability for the lenses.

Rimless glasses were a popular style of eyeglasses in America from the 1880s until into the 1960s, and re-emerged in popularity in the latter part of the 20th century and early 21st century.

Origins

The template for rimless eyeglasses date back to the 1820s, when an Austrian inventor named J.F. Voigtlander marketed a rimless monocle
Monocle
A monocle is a type of corrective lens used to correct or enhance the vision in only one eye. It consists of a circular lens, generally with a wire ring around the circumference that can be attached to a string. The other end of the string is then connected to the wearer's clothing to avoid losing...

. The design as it is known today arose in the 1880s as a means to alleviate the combined weight of metal frames with heavy glass lenses. The style also came about from a desire to make eyewear as inconspicuous as possible; at the time, eyeglasses were not considered an acceptable fashion statement and carried connotations of one being elderly or a member of the clergy

During this same period, another style became available in which the lenses were mounted to two arms as well as a bridge; the style became known as three piece glasses for the three separate structural components. The most popular three piece style was known as a riding temple, and was modeled after a style of eyeglasses favored by those who relied on horses for transportation. The style lacked nosepads, and featured small, oval lenses designed to sit flush with the face by way of the combined efforts of curved temples that conformed to the back of the wearer's ears and a curved nosepiece that conformed to the bridge of the nose. The design eliminated any obstruction of vision caused by eyeglass frames and also kept the glasses secure on the wearer's head.

, the pince nez became less practical because of subtle shifts in the position of the lenses caused by the wearer moving his or her head. With the implementation of nosepads in 1920, the three-piece style surpassed the pince nez in popularity; the new design allowed wearers to adjust the position of glasses on the face, and also permitted for a wide variety of lens shapes, with optometrists offering over 300 options by 1940 (though variations on circles, ovals, and octagons remained most popular).

Also in the 1920s, a new style appeared in which an "arch" connected the bridge to the temples, to provide extra stability for the lenses; the mounting technique was referred to as "Shurset" ("sure set") . Although the design would be considered a variant of "semi-rimless" glasses in the latter part of the 20th century, the style was considered rimless upon its inception because no part of the lens was secured inside of a frame; modern semi-rimless eyewear features lenses partially secured inside of a half-frame, with the lower portion of the lens held in place by nylon wire. Though traditionally called "Rimways," this variation was also referred to as Cortland style . A variation utilizing only two screws and which only secured the lenses to the bridge was called the Numont or the Two Screw Cortland ; the removal of the temporal screws was considered to be a cosmetic improvement.

Three-piece glasses with temples and nosepads remained popular from the 1920s until the end of the 1950s; during the same period, Rimway glasses began to edge them out in popularity, and once three-piece glasses had fallen out of favor, remained in style into the 1960s

1980s

Rimless glasses began to become popular again in the latter part of the 20th century, particularly a brief renaissance in the 1980s. In the 1980s, Rimways were often featured in movies to indicate that a character was an intellectual; Wilford Brimley wore a pair as scientist Blair in The Thing, as did Corey Feldman while playing a child inventor in Friday the 13th: The Final Chapter

Durability and stability

Because they lack frames, rimless glasses can sustain damage more easily than other eyeglasses designs; eyeglass labs throughout the United States report that consumers are two to ten times more likely to require new lenses in three-piece frames than any other eyeglass design. This is nominally a result of the material used to produce the lenses: Although relatively durable inside of frames, CR-39 lacks impact resistance and cannot absorb the wear and tear

 of constant stress to the lenses caused by putting on, wearing, and removing glasses. Rimways fare much better with CR-39 because the arches absorb shock and stress. The implementation of polycarbonate-- the material used to make bullet proof glass-- in addition to making rimless glasses even lighter, reduces the glasses' fragility as polycarbonate can endure a great amount of stress and is highly impact resistant. To ensure both the longevity of the glasses and as a safety precaution, more optical labs are refusing to mount CR-39 lenses in rimless frames, and British

optical labs have uniformly adopted a policy of only processing polycarbonate lenses for rimless frames.
