Eyeglasses in the modern market come in different sizes, colors, shapes and so forth. There are continual changes in this market, partly because customers always issue new requirements and personal needs. Even if the overall eyewear market is unpredictable, one thing is for sure that the time when big eyeglasses dominated the whole field has gone for ever. It is true that some classic eyeglasses styles, such as cat-eye and but-eye, are still widely available as retro products. But it is more important to realize that these products have never regained a leading role, which was definitely a fact one or several decades ago. When it comes to the reevaluation of eyeglass size, it is easy to classify eyewear models into big ones and small ones or probably medium models. Currently all these sizes are optional. But it is undeniable that small glasses are the mainstream.

The leading role claimed by eyeglasses with small lenses has been largely contributed by the cute appearance of these products and their ability to disguise the use of thick lenses. These benefits lead lots of Rx eyewear users to select small-sized frames. But never assume that these glasses are the best for everyone. Big eyeglasses never fade out. On the contrary, eyeglasses with large lenses have been traditionally favored by people with elegant vocations, which require a formal image. For instance, large glasses in a near-square shape are really a classic design that is the most popular choice among politicians, lawyers and policemen.

For most young ladies and gentlemen, small-size eyeglasses may look more attractive. But they also cause a difficulty in lens fitting. Since these glasses are supposed to offer vision correction, proper prescription fitting is the foremost task. Cutting lenses into small ones will inevitably sacrifice certain optical features of the lenses. In addition, the widespread application of bifocal, trifocal and progressive lenses further highlights the advantage of big eyeglasses. It is much easier to accommodate several or a couple of powers or focal powers in a single lens that is larger in size.
