Buy Glasses For Kids - Appropriate Frame Material
Metal and other materials are heavy, easy to rust, easy to deform, easy to lead to children's facial allergies, and oppression of the bridge of the nose and temple. Resin glasses are colorful, and the price of the material is beneficial. Because the child is in the development period, glasses are changed more frequently. Therefore, summarizing the above factors, the resin frame is the most suitable for children to wear. A high degree of myopia must choose a small frame. If the child's myopia or farsightedness is high, the lens will be very thick, so be sure to choose a small frame. Because the frame type is small, coupled with the lightweight of the resin frame, it has better fixing performance than other materials.

The anti-reflective yellow and amber lenses are the best choices for outdoor vision protection, as they reduce high-intensity glare from bright lights (headlights, LED signs, etc.) at night. They are suitable for daytime driving with a clear vision, especially in low light conditions such as rain, haze, and winter.

Which kind of lens can correct myopia?
Myopia is corrected by glasses with concave lenses, which are the thinnest in the center and thicker at the edges. The strength of the lens used to improve myopia is measured in diopter (D). The prescription for myopic glasses always begins with a minus sign. The higher the magnification of the lens, the better the effect of correcting myopia. High refractive index lenses are usually recommended to correct myopia with a diopter greater than -3.00. The lenses are thinner and lighter than regular plastic lenses, making them more attractive and comfortable. At the same time, an anti-reflective coating is strongly recommended for the correction of myopia lenses. The augmented reality coating eliminates scattered reflections in the lenses, making them look thinner and more attractive.

If you need reading glasses when using a computer, you may want to choose a lower reading glasses power. This is because most people view their screen from a greater distance from their eyes than when they are reading a book or a magazine.
However, if you need reading glasses for looking at something very close or very small, you may need a pair of stronger power glasses.
In most cases, when two reading glasses’ powers seem equally suitable, choose the glasses with the lower power. Picking reading glasses that are too string typically will cause more discomfort problems than reading glasses that are a little too weak.
