Children's Vision Problems Cannot Be Ignored
In today's digital age, children have increasing access to electronic devices, and vision problems are becoming more common. According to relevant data, the overall myopia rate among children and adolescents in China has reached a worrying level, with some areas even exceeding 50%. Childhood is a crucial stage for vision development. Once vision problems such as myopia, hyperopia, or astigmatism occur, if not corrected in a timely manner, it will not only affect children's study and life but may also lead to permanent vision damage and even serious complications such as retinopathy and glaucoma.
Children's prescription glasses, as an important tool for correcting vision, are particularly important. They can not only help children see clearly but also control the rate of vision decline to a certain extent. However, the quality of children's prescription glasses on the market varies. Choosing a pair of safe and suitable glasses has become a difficult problem for parents. This is where certifications play a key role.
Why Are Certifications Crucial?
When choosing children's prescription glasses, certifications are an important basis for measuring their quality and safety. Glasses that have passed certifications indicate that they meet certain standards in all aspects and can effectively protect children's vision.
The EN ISO 12312 - 1 standard focuses on the impact resistance test, which is particularly important for active children. In daily life, children may accidentally bump into their glasses. If the impact resistance of the glasses is poor, the lenses are likely to break, causing serious harm to the eyes. Glasses that have passed the EN ISO 12312 - 1 certification have undergone strict impact resistance tests and can withstand a certain degree of external impact, greatly reducing the risk of lens breakage and providing a safety barrier for children's eyes.
The FDA 21 CFR 801.410 standard strictly limits the nickel release of the frame, requiring it to be less than 0.5μg/cm²/week. Nickel is a common allergen. Long - term contact with frames with excessive nickel content may cause allergic reactions on children's skin, such as redness, itching, and rashes. This not only makes children uncomfortable but may also affect their daily life and study. Frames that meet the FDA 21 CFR 801.410 standard can effectively reduce nickel release, reducing the risk of skin allergies in children and making them more comfortable and safe to wear.
Two Certification Standards You Must Know
(1) EN ISO 12312 - 1 (Impact Resistance Test)
The EN ISO 12312 - 1 certification standard has a strict and scientific testing process to ensure the impact resistance of glasses. In a professional laboratory environment, various scenarios where glasses may be impacted are simulated. For example, a specific impact device is used to shoot a steel ball of a certain mass and size at the lens at a precisely controlled speed, simulating the impacts that glasses may receive when children are exercising or playing. Only glasses that pass this strict impact resistance test are considered to meet the standard.
In daily life, such high standards are of great significance. For example, when children are doing sports such as running, playing basketball, or skipping rope, collisions are inevitable. If the impact resistance of the glasses is poor, they are likely to break during a collision, and the broken lenses may scratch the children's eyes, face, and other parts, causing serious physical harm. Children's prescription glasses that meet the EN ISO 12312 - 1 standard are like a sturdy armor for children's eyes, able to withstand a certain intensity of impact and greatly reducing the risk of eye damage in case of an accident.
(2) FDA 21 CFR 801.410 (Frame Nickel Release < 0.5μg/cm²/week)
Nickel is a common allergen, and children's delicate skin is easily prone to allergic reactions when in long - term contact with frames with excessive nickel content. Many children may experience symptoms such as skin redness, itching, and rashes due to wearing glasses with excessive nickel release, seriously affecting their quality of life and health. To avoid this, the FDA 21 CFR 801.410 standard strictly limits the nickel release of the frame, requiring it to be less than 0.5μg/cm²/week.
During the production process, glasses manufacturers need to use advanced materials and processes to strictly control the nickel content and release in the frame. When choosing frame materials, low - nickel or nickel - free alloy materials are preferred to reduce the risk of nickel release from the source. In terms of production processes, special coating treatments or surface protection technologies are used to further prevent the release of nickel ions. In this way, frames that meet this standard can provide a safe wearing environment for children, reassuring parents.
Common Mistakes Parents Make: Don't Let Your Child's Vision Be Ruined by "Good Looks"!
(1) Case Warning: The Hazards of Large - Frame Glasses
In the pursuit of fashion and personalization, large - frame glasses have become a favorite of many children and parents. However, such a choice may bring unexpected harm to children's vision. A British mother bought a pair of large - frame glasses for her child to make the child look more fashionable and cute. At first, the child was happy wearing the new glasses, but soon, the child frequently complained to the mother that the eyes were uncomfortable, always felt tired, and dizzy after looking at things for a long time. After taking the child for an examination, the mother found that the child had a very serious visual fatigue problem, and the culprit was the pair of large - frame glasses.
Large - frame glasses are prone to causing these problems because their large size often makes it impossible for the optical center of the lens to accurately align with the child's pupil center. When a child looks through the area of the lens that deviates from the optical center, a prism effect occurs. This not only distorts the objects the child sees but also greatly increases the eye's adjustment burden, leading to discomfort symptoms such as visual fatigue and dizziness. Moreover, large - frame glasses have a large lens area and relatively heavy weight. Long - term wearing can easily press on the child's nose and ears, further reducing wearing comfort and affecting the child's eye health.
(2) Correcting Misconceptions
When choosing children's prescription glasses for their children, parents must correct the wrong concept of only looking at the appearance. The primary purpose is to correct the child's vision and ensure vision health. We must not ignore the key vision parameters just for the sake of good looks. Pupillary distance is a crucial parameter in the process. It refers to the distance between the centers of the two pupils. A suitable pupillary distance can ensure that the optical center of the lens coincides with the child's pupil center, allowing the child to obtain the best visual effect. If the pupillary distance does not match the frame, even if the glasses have the correct degree, it will damage the child's vision.
In addition to the pupillary distance, factors such as the frame's material, weight, and comfort cannot be ignored. In terms of material, choose safe, environmentally friendly materials that are not likely to cause allergies. In terms of weight, choose a lightweight frame as much as possible to reduce the burden on the child's nose and ears. Comfort is reflected in whether the frame design fits the child's facial contour, and whether the length and curvature of the temple are appropriate. Only by comprehensively considering these factors can we choose a pair of suitable and comfortable children's prescription glasses for the child, truly safeguarding the child's vision health.
How a Good Pair of Children's Prescription Glasses Should Be Designed
(1) Design That Fits a Child's Face
Children's facial bones and muscles are still growing and developing, and their facial structures are very different from those of adults. Therefore, the design of a good pair of children's prescription glasses must fully consider the characteristics of a child's face.
In terms of material selection, lightweight materials such as TR - 90 are usually used. TR - 90 is a memory - type polymer material. It is much lighter than ordinary plastic materials, effectively reducing the burden on the child's nose and ears. Even if the child wears it for a long time, there will be no obvious sense of pressure. According to relevant data, the weight of a frame made of TR - 90 material is approximately 30% lighter than that of an ordinary plastic frame, greatly improving wearing comfort.
An adjustable nose pad is also an important element in the design of children's prescription glasses. The height and width of the noses of different children vary. An adjustable nose pad can be adjusted according to the shape of the child's nose, making the glasses fit the nose better, reducing the shaking and slipping of the glasses. This not only improves wearing stability but also avoids poor vision correction effects caused by the shaking of the glasses. Moreover, proper adjustment of the nose pad can also disperse the pressure of the glasses on the nose, reducing the child's discomfort on the nose and reducing the potential impact on the development of the nose due to long - term wearing of glasses.
(2) The Unique Advantages of Silicone Temple Tips
Silicone temple tips are an ideal choice for children's prescription glasses due to their soft and skin - friendly characteristics. Compared with traditional plastic or metal temple tips, silicone temple tips will not irritate the delicate skin of children's ears, effectively avoiding problems such as skin allergies and redness. Even if the child wears the glasses all day, the ears can remain comfortable.
Silicone temple tips also have a unique advantage in that they can soften and shape according to the temperature of the ears. In a 45℃ environment test in the laboratory, researchers found that when the silicone temple tips are exposed to an environment simulating the temperature of the human ear, the material will gradually soften and become more flexible. This is because when the silicone molecules are heated, the intermolecular forces weaken, allowing the silicone to deform more easily. As the temperature rises, the silicone temple tips will gradually fit the contour of the ear, forming a comfortable wearing state. When the temperature drops, the silicone temple tips will remain in the shape that fits the ear, providing the child with a stable wearing experience.
This characteristic of softening and shaping according to the ear temperature enables the silicone temple tips to adapt to the shapes and sizes of different children's ears, providing a more personalized wearing experience. Whether a child has wider or narrower ears, they can obtain a comfortable and stable wearing effect through the automatic adjustment of the silicone temple tips. This not only improves the child's wearing comfort but also reduces the frequent slipping of the glasses caused by improper temple tips, making the child more at ease in study and life.
