Concept in Definition ABC

Lenses are one of the most useful and necessary inventions that humans developed since they allow you to enjoy a better quality visual as well as today contribute an interesting aesthetic sense to the appearance. When we talk about lenses we must enter the world of physical and optics since, despite looking like simple objects, the lenses suppose a certain level of complexity in regards to your functioning.

The earliest forms of lenses known to the present they were small pieces of glass modeled in terms of size according to the specific need of the user. These pieces of glass were not attached to any specific structure like frames are today and In addition, they were not usually worn permanently if not separated from the body (that is, not placed on it) occasionally. The most modern lenses began to have structures of support for or support that greatly facilitated its use.

The lenses can be described as elements normally made of glass (although currently we can also find lenses made of acrylic or transparent plastic) that reflect light due to their arched shape and that allow the person to have a better vision of what focus. The lenses can be physically adapted to different needs and that is why there are lenses to see far away and lenses to see closely, glasses to read or to rest the eyes, etc. Lenses or sunglasses are those that have a dark or more polarized glass that facilitates vision in situations in which the presence of sunlight or

artificial it is very abundant. These lenses are perhaps the most developed in stylistic terms and today there are numerous brands that are dedicated exclusively to the design of new and amazing sunglass frames.
