In the eyewear world, it is recognized by the public that male wearers concern more about eyeglass frame fit, comfort and durability. And women buyers pay more attention to the appearance of eyeglasses. This is generally true even if there are some people believing that all these factors are important for both men and women. Among these factors and related requirements, fit and comfort can be put at the first place either in women’s and men’s styles. And these two requirements are closely associated with flexible frames. It is true that comfort and fit depend on mainly the original manufacturing of eyeglass frames. For instance, the temples should be long enough but do not dig into the side of the wearer’s head. And the frame should firstly be large enough but not be too large. All these are basic aspects that have been determined during the frame production. However, another critical point linked with comfort and fit is the flexibility of the eyewear frame.
Flexible frames allow the wearer to make slight adjustment when there is any discomfort or unfitness. This is very helpful because comfort and fit are absolutely necessary for both male and female users. Fashionable ladies should pay equal attention to these two factors because wearing a pair of stylish yet uncomfortable eyeglasses or sunglasses will certain turn into an unpleasant experience. Flexible eyeglass frames can be made of various materials, including plastics and metals. Actually it is a trendy that frame flexibility is commonly pursued by modern eyewear users.
Generally speaking, plastic frames are more flexible than metal ones. This conclusion is based on the traditional judgement of the natures of plastic and metal. In fact, some mixed metals or alloys are also feasible to make flexible frames. Nylon is to some extent flexible and is a premier material for sports eyewear frames. And polycarbonate is also a good material for flexible eyeglasses. Within the metal category, beryllium, Monel and Flexon are good options.
