What are acetate sunglasses?
Cellulose acetate is a thermoplastic resin obtained by esterification of acetic acid or acetic anhydride under the action of a catalyst. CA is resistant to water, gasoline, mineral oil and lipids, weakly alkaline solutions, and acids. It has good weather resistance. It is not resistant to ethanol, strong acids, and strong alkali solutions. Acetate was one of the first synthetic fibers that were first made. The higher the quality of acetate fiber, the better the glossiness and transparency. Acetates consist of (biological) polymers derived from wood (tree) pulp and/or natural cotton fibers.
Features of Scetate Sunglasses Frames
The sunglasses with acetate fiber plate milling processing become plate frames. Plate frame is not easy to burn, in small proportion, with hardness. In addition, it has good gloss, durable, but is not easy to bake processing. Acetate fiber particles that used injection molding machine extrusion molding are known as the injection molding frame. Its characteristic is to save raw materials and can be produced in large quantities. The cost is lower, the price is cheaper than the plate frame. Environmentally friendly, it is made of renewable materials, hypoallergenic, available in a variety of colors. Today’s premium acetate fiber frames are known for their light, thin construction and strength.

Acetate Sunglasses Frames and Prescription Lenses
Acetate sunglasses frame and prescription lenses are not in conflict, but the selection of optical lenses should pay attention to the frame of sunglasses. People with high myopia can not choose frameless sunglasses, large frames (similar to the frame of sunglasses). The big Sunglasses will shift the optical center of the lens, so there is a big deviation from pupil distance, producing a phenomenon of not clear content.
