In the long river of human history, cheapest eyeglasses are like an indispensable invisible guide, leading us through time and space to explore the origin of this visual treasure. Although the inventor of the first eyeglasses, Florentine Salvino Deli Almati, has long since been laid to rest in a corner of Paris, his legacy continues to bloom around the world.
The early development of eyeglasses is closely related to Venice in the 13th century. When the magic of transparent glass was born, glasses were also skillfully displayed. Venezia, as the cradle of glasses, laid the foundation stone for the inheritance of this optical craft. However, the first glasses were not portable and practical, but some magnifying glasses with handles, which was slightly inconvenient.
Over time, glasses have undergone a long and magnificent metamorphosis. In 1310, France witnessed the birth of glasses consisting of two circular lenses, which brought convenience to short-sighted people. Although the Venetian eyeglass craft was kept secret, the production secret quickly spread to Germany, France and the Netherlands, and the eyeglass manufacturing industry began to flourish, and the technology was spread across the sea to the Far East.
The unique signs of different cultures are also deeply depicted in the evolution of glasses. In the Far East, glasses were worn on the top of the head, while in Europe in the 17th and 18th centuries, a design was popular which was fixed to the bridge of the nose by a spring. It was not until the 19th century that we ushered in the shape of today's glasses, ending a long history of more than 700 years of change. From their initial curiosity, glasses have evolved into a medical tool for correcting vision and protecting the eyes.
However, with the development of society, glasses are no longer just a medical tool, but also a part of fashion. The prevalence of colored glasses is not only a resistance to strong sunlight, but also a fashion ornament. However, science reminds us that we need to be careful about wearing colored glasses. Misuse of colored glasses can damage retinal tissue, making the eye gradually lose its ability to adapt to night light.
In today's technologically advanced era, we have been able to scientifically prove that colored glasses do not always work. Normal light stimulation can not only maintain visual balance, but also help to maintain the overall physiological balance. Therefore, choose to wear glasses need to be careful, the maintenance of eye health is the most critical.
In general, the evolution of glasses is like an epic of ups and downs, recording the exploration and pursuit of human vision. From the tombstones of Florence to the origins of Venice to the diversified use of eyeglasses today, every step is the crystallization of human wisdom. Perhaps, through the glasses, we not only see the clarity of the world, but also find their own continuous interpretation of the wonderful chapter.
