If you have been buying reading glasses for a while you probably realize that frame quality is just as important as lens quality. 

High quality frames are made to regulated ophthalmic standards so that they can endure everyday wear, can be easily adjusted for a more personal fit, have quality screws and hinges that allow for their maintenance and as a result those frames are also suitable for prescription lenses if you should choose.

For frame materials, plastic (also known as zyl or cellulose acetate) is one of the most popular choices in reading eyewear.  Cellulose acetate is a natural plastic, which is manufactured from purified natural cellulose. Natural cellulose in the appropriate mix is derived from two basic sources, cotton linters and wood pulp. It is hypoallergenic and known for being strong, lightweight, and flexible. Cellulose acetate can also be made up in a wide range of colors and finishes. For eyewear, cellulose acetate is used by forming layers of plastic into large blocks then carefully dividing it into individual parts, hand polishing and finally assembling them into a frame. This is an extremely labor intensive process and if done properly from start to finish can take at the very least 8 weeks!

Stainless steel is another material used in manufacturing reading glasses. It’s lightweight, corrosion resistant and durable; it’s also hypoallergenic and more moderately priced in comparison to other metals. Metals of a titanium based alloy know as memory metal return to their original shape even after bending. They are lightweight, flexible, and hypoallergenic. Metal frames can be tweaked for a more personal fit since they have nose pads that can be easily positioned to contour your nose. There are many other materials used in frame manufacturing but these are the materials that Renee's READERS uses. We feel these frame materials provide you with the best quality and we know that quality is basic to easy stylish living.
