Today there are many people buying brand name and popular designer eyeglasses. They have evolved from the old style glasses without much personality, to extreme statements of fashion. Today a celebrity has to have eyeglasses that can reflect their total fashion statement, and accentuate their uniqueness, and become a part of who they are. They need to be trendy, and they need to be chic.
When these eyeglasses first came on the scene, they were more of a tool than any kind of fashion enhancement. But long gone are those days. Now, they are even more aligned with fashion, than in assisting in the vision they were intended for. This is especially true among celebrities. They want their eyeglasses to be unique, attractive, and for them to set off their style and flare for fashion.
The silver lining in all this, is that a person has more choices than they could possible know what to do with. There are so many various styles, shapes, colors, sizes, and materials to choose from, it is nearly impossible to see them all in a day. You can be taken from the old librarian look and be made over to look like a runway model with a simple change of eye-wear. It is really amazing.
