Introduction
Ring focus myopia prevention and control glasses, also known as defocus lenses or face-controlled lenses, are the fourth generation of multifunctional lenses. These lenses have gained popularity in recent years due to their ability to reduce the progression of myopia and correct focal issues at the edges of the visual field. With a gradual decrease in diopter from the center to the edge of the lens, these glasses help control the growth of the eye axis and delay the development of myopia.
Originally developed and produced by Zeiss in Germany around 2010, the technology behind ring focus lenses has since spread to many other lens factories, resulting in a decrease in costs and increased availability in the market. These lenses are particularly effective in preventing and treating juvenile myopia (ages 4-16) and have shown remarkable results.
Blue Light and its Effects
To understand the significance of ring focus myopia prevention and control glasses, it is important to familiarize ourselves with blue light and its effects on our eyes. Blue light is emitted by electronic devices such as computers, smartphones, tablets, and LED TV displays. With the increasing use of these devices in our daily lives, our exposure to blue light has also dramatically increased.
Blue light falls within the wavelength range of visible light, specifically between 380-580 nm. However, high-energy visible (HEV) light, including blue-violet light emitted by digital devices, can be damaging to our eyes. Prolonged exposure to blue light can lead to several issues such as headaches, sore or tired eyes, and even affect our sleep patterns. It can also have adverse effects on our skin and cause stiffness in the neck.
SHINU Anti Blue Light Lenses
To address the harmful effects of blue light, SHINU offers anti blue light lenses made of CR39 with a refractive index of 1.60. These lenses employ German advanced technology, specifically multi-wavelength nano-coating technology, to provide comprehensive protection against ultraviolet light, radiation, and harmful blue light. The inner layer of the lens is coated with a green film, while the outer layer is coated with a blue film.
The SHINU anti blue light lenses have been proven to be 20% more effective in providing comprehensive protection compared to ordinary green coating films. By wearing these lenses, individuals can greatly reduce their exposure to harmful blue light emitted by digital devices, thus protecting their eyes from potential damage.
Frequently Asked Questions
1. Are ring focus myopia prevention and control glasses suitable for all age groups?
Ring focus myopia prevention and control glasses are primarily designed for the prevention and treatment of juvenile myopia in the age range of 4-16 years old. However, they can also be used by individuals of other age groups who may have issues with myopia. It is recommended to consult with an eye care professional to determine the suitability of these glasses for your specific needs.
2. Can ring focus myopia prevention and control glasses completely eliminate myopia?
While ring focus myopia prevention and control glasses have shown remarkable results in preventing and delaying the progression of myopia, it is important to note that they are not a cure for myopia. These glasses can help control the growth of the eye axis and reduce the shape deprivation associated with myopia, but they may not completely eliminate the need for other vision correction methods such as traditional eyeglasses or contact lenses.
3. How do SHINU anti blue light lenses compare to other options in the market?
SHINU anti blue light lenses are made of high-quality CR39 material and employ advanced multi-wavelength nano-coating technology to provide comprehensive protection against blue light. Compared to ordinary green coating films, SHINU lenses have been proven to be 20% more effective in protecting the eyes from harmful blue light. However, there are several other options available in the market, and it is important to choose lenses that suit your specific requirements and preferences.
In conclusion, ring focus myopia prevention and control glasses offer a promising solution for individuals looking to prevent and control the progression of myopia. With their unique design and innovative technology, these glasses provide effective myopia control, especially for juveniles. Additionally, SHINU anti blue light lenses offer comprehensive protection against harmful blue light emitted by digital devices, ensuring the health and well-being of your eyes.
