Basically, anyone who wears glasses will choose resin lenses. Although glass lenses were very popular in the past, they still have many disadvantages. With the continuous development of technology, high-end resin lenses can better meet our needs. And resin lenses can be matched with different frames, so there is no need to worry about problems. Vooglam glasses currently mainly use resin lenses, but glasses with glass lenses may be updated later. Today we will briefly introduce the advantages and disadvantages of glass lenses. It is also best for everyone to understand the different types of lenses before making a choice.
What are the advantages and disadvantages of glass lenses?
Advantages Glass lenses are relatively transparent. After all, many people used such glass lenses in the past, so many manufacturers are now producing high-end glass lenses. However, there are certain limitations when different types of glass lenses are matched with eyeglass frames. Light comfortable frames are now more popular, so you still have to buy suitable lenses according to the frames you choose. From a practical point of view, glass lenses are not easy to change color and can still be used for a long time, so glass lenses are still worth choosing, and the price is also more favorable.
Disadvantages After all, it is a glass product. Even with the continuous improvement of current technology, the weight of the lens cannot be reduced. For myopic friends, especially those with high myopia, using such lenses may affect their nose bridge and breathing. Moreover, glass lenses cannot be coated. The more popular aspherical lenses are still mainly resin-based, and such products are the most worthy of our choice.
Teach you how to choose myopia glasses lenses
The lens is also called the mirror core. It is suitable for being clamped in the frame, so it is called the mirror core. Its form can be horizontal or vertical, and it is a simple and convenient installation style. Lenses can be divided into four types according to different materials: resin lenses, special lenses, space lenses, and glass lenses.
Which lenses are best for myopia glasses? Not everyone is suitable for myopia surgery, so wearing glasses is still the main method for correcting myopia for many people. What materials are myopia spectacle lenses made of? To compare which lens is the best for myopia spectacles, you need to first understand what types of myopia spectacle lenses are available.
Myopia glasses material
The types of myopia spectacle lenses can be divided into inorganic materials and organic materials in terms of materials used. From the development of myopia spectacle lenses, they can be divided into natural crystal lenses, optical glass lenses, and optical resin lenses. Eye experts point out that the best myopia spectacle lenses are the lenses that can best protect your eyes while correcting myopia.
Which lenses are best for myopia glasses?
Which lens is best for myopia glasses needs to be considered from three aspects: imaging effect, whether it prevents eye fatigue, and whether it protects against harmful ultraviolet rays. Studies have found that crystal sheets cannot effectively protect against ultraviolet rays, and there are many natural minerals and impurities in them, and the optical imaging effect is not good.
They have been basically eliminated now; glass lenses are not enough to protect against ultraviolet rays and can only protect against 350nm, and the wavelength of ultraviolet rays is 295nm. -380nm; resin lenses may protect against UV rays between 350nm and 380nm (some can also protect against UV rays above 380nm). Of course, there are many kinds of films to choose from. After the film is added, it can increase the surface hardness of the lens and prevent eye fatigue and other functions.
Glass lenses and resin lenses
Currently, the most commonly used myopia spectacle lenses on the market include glass lenses and optical resin lenses. Glass lenses have high hardness and good wear resistance. Generally, their quality and parameters will not change over time. Resin lenses are divided into spherical lenses and aspherical lenses according to type. Compared with spherical lenses, aspherical lenses have smaller peripheral differences, see more realistically, and are more beautiful to wear; and the higher the refractive index, the thinner the lens and the higher the hardness. Since resin lenses are much lighter than glass lenses, have better UV protection, and have better impact resistance than glass lenses, optical resin lenses are better and suitable for teenagers, people with high refractive errors and athletes.
The quality of glasses mainly depends on the lenses
The quality of glasses mainly depends on the lenses, while the price of glasses mainly depends on the frames. Therefore, the quality of myopia glasses is not directly proportional to the price. People with myopia should not be greedy for cheap and buy glasses casually, nor should they blindly seek high prices to wear unsuitable glasses. They should go to a professional eye hospital or institution for examination and wear glasses that are suitable and cost-effective based on their own eye conditions.
How to choose spectacle lenses for myopia? When wearing spectacles for myopia, the lenses will greatly affect the future vision of the eyes and will also have a corresponding protective effect on the eyes. So how should I choose lenses? Choose lenses based on factors such as their basic material and performance. When choosing lenses, you should consider various factors such as the suitability of the power and self-fitness to choose the right lenses.
