Acetate:

Made by chemical synthesis using cellulose and other chemical compounds to produce a durable plastic that can be used to construct frames.

Acuity:

The clarity or sharpness of vision provided by various lens materials and/or coatings.

Acrylic:

Consists of polymers of acrylic acid or acrylates. Sunglass frames can be made from this.

Amber Lens:

Recognized as effectively improving acuity in scattered blue lighting conditions caused by haze, smog or fog. Offering an enhanced clarity in high glare conditions; these are a popular choice for activities such as boating, skiing, and driving. E.g., Brown Lens

An optical coating typically applied to the lens surface of eyewear, in an effort to reduce reflection.

Arm:

Also referred to as the Temple; this piece attaches to the frame and stretches behind the wearer’s ears, holding sunglasses in place. E.g., Side-Piece, Frame-Arms & Temples.
