Origins

Tortoiseshell is a color named after a tortoiseshell turtle, and tortoiseshell plates have a magical translucent pattern. Since the color of the scales pattern on the back of tortoiseshell turtles is very beautiful and fashionable, it has become a sought-after fashion trend. Although tortoiseshell is a precious product, it is highly poisonous and cannot be eaten, but the medicinal herbs made from it have the function of clearing away heat and detoxifying the toxins, and because of its high hardness and low density, tortoiseshell is used in the glasses industry to make frames and mirror frames more commonly.

Modern

Today's tortoiseshell frames are mainly made of acetate, an environmentally friendly material. Tortoiseshell frames have a high refractive index and an elegant color, so they reflect harmful glare, such as ultraviolet rays and infrared rays, and make you look good when you wear them. At the same

Acetate frames are made from a plant-based plastic called cellulose acetate, known for its flexibility, durability and comfort. A durable choice in eyewear, acetate frames are lightweight, comfortable and hypoallergenic, which also makes them ideal for people with sensitive skin. Acetate frames are available in a wide range of patterns and styles making them a favorite among those seeking style and wearability.

Acetate is a popular material for eyeglass frames and offers a variety of benefits to eyeglass wearers.

Stylish: Acetate can be designed with colorful patterns, different layering, and a multitude of available colors, and recessed designs can maintain their characteristics more effectively. Multiple colors and patterns enhance style versatility and personalize fit.

Durability: The acetate frame is made of plant-based materials that are sturdy enough to withstand some daily wear and tear, making it the first

Immediately into the hot summer, the face of high temperature and heat, all aspects of our body is also subjected to a "big test" we will go out and apply sunscreen to avoid skin tanning and sunburn, but do not ignore our "window to the soul" - eyes, in the heat of the day, whether indoors or outdoors, our eyes are also vulnerable to injury Oh, so how to protect it? -Eyes, in the heat of the day, whether indoors or outdoors, our eyes are also easy to hurt Oh, so how to protect it?

What are the injuries that the eyes are most afraid of in hot weather?

High temperature heat, our eyes are most afraid of ultraviolet radiation brought about by the damage, because of the strong ultraviolet radiation is prone to produce a variety of ophthalmic diseases. Acute injury is instant exposure to strong UV sunlight, this type of injury is generally within six hours will damage the cornea, resulting in corneal epithelial cells produce detachment phenomenon,

Progressive multifocal lenses, also known as progressive lenses, are lenses that have more than one focal point on them, and cosmetically, progressive multifocal lenses are no different from regular lenses. As we age, our eye adjustment begins to decline, causing difficulty in near vision, so that in close work, we may need to add convex lenses to our static refractive correction in order to have clear near vision. Progressive lenses were originally designed to provide a natural, convenient and comfortable correction for presbyopes. Wearing progressive lenses is like using a video camera to videotape a pair of eyeglasses that allow you to see clearly at a distance, as well as close up, and to see mid-distance objects. This is why we also describe progressive lenses as "zoom lenses", a pair of eyeglasses is equivalent to multiple eyeglasses. Progressive lenses are mainly suitable for people who have insufficient adjustment or who have an inward slant.

Myopia, a global health problem, can affect people of all ages and demographics. It is not only a threat to our visual health, but also a major concern that affects our quality of life. So, how to prevent myopia? This article will provide you with a series of scientific and practical suggestions to help you stay away from myopia.

The causes of myopia

Myopia is caused by a combination of genetic, environmental, personal behavior, and dietary factors. Genetic factors, such as a family history of myopia, increase the risk. Environmental factors, such as prolonged close eye use, excessive eye use, and poor reading environment, also contribute to myopia. Personal behaviors, such as poor posture, reduced blinking, and reading in low-light conditions, may impair vision. Additionally, an unbalanced diet and lack of essential nutrients can also affect vision development and increase the risk of myopia.

The "anti-blue light" label is certainly a buzzword for electronic protection products, and in the eyewear industry, "anti-blue light glasses" are a consumer buying trend. Good blue light glasses can block the blue light emitted by electronic displays from harming the human eye. However, when you buy blue light protection glasses, you may find that blue light protection glasses are divided into two categories: lenses with base color and lenses without base color. So how to choose? Should blue light glasses lenses have a base color or not? This article will give you scientific and reasonable answers.

How Lens Base C

Blue light is part of natural light and has an important effect on our physiological rhythms. However, the blue light emitted by electronic displays is fundamentally different from the blue light found in natural light. Prolonged exposure to this high-energy blue light can aggravate eye strain and even cause various problems. This article will explains the dangers of blue light and the need to block it.  

Understand Blue Light

Blue light is high-energy visible light with a wavelength of 400-500nm, which is divided into harmful blue light with a wavelength of 415-455nm and beneficial blue light with a wavelength of 480-500nm. Anti-blue light glasses are mainly designed to prevent the harmful blue light of the shorter wavelength.

Harmful

In the realm of vision, the Abbe number is a crucial but often overlooked factor. While terms like diopter and lens thickness may be more familiar, the seemingly obscure Abbe number actually plays a significant role in determining the quality and visual performance of eyeglass lenses. This article explains what the Abbe number is and how to choose the right eyeglasses based on its size.

Definition of the Abbe Number

The Abbe number is a measure of a transparent medium's dispersive power. It reflects how much different wavelengths of light are dispersed as they pass through the lens. A higher Abbe number means lower dispersion of the lens and a clearer visual effect.

Importance of the Abbe Number

Low Abbe number lenses can affect your ability to judge the shape and color of objects, strain your

Myopia is a type of refractive error. When the eye is relaxed, parallel light rays enter the eye and focus in front of the retina, which results in an inability to form a clear image on the retina, called myopia. Also, the farther the light is projected from the retina, the greater the degree of myopia. When light is reflected behind what we call the retina it is farsighted and it receives astigmatism when it is projected to a different point. This is all familiar, but did you know that myopia is also divided into true and false myopia?

False myopia occurs mostly in adolescence, but because of the emergence of smartphones and tablets in recent years, the eye habits of adults have changed a lot from the past. Prolonged close reading, reading text that is too small, and operating the computer for too long can overuse the eye's ability to regulate. This has caused adults to start developing pseudomyopia as well. So what is pseudomyopia? And what is true myopia?

Eyewear is not only a companion at work, but also a fashion statement in everyday life. Frames are an important part of eyewear, and unique and subtle frames can add an extraordinary charm to eyewear. This article aims to provide a comprehensive guide to help you learn more about the world of frames.
