Wenzhou Wanrun Glasses Co., Ltd.: Several misunderstandings about presbyopia gla

Details

Children should first choose glasses according to whether they are stable and comfortable to wear, and then choose appropriate size and shape according to lens thickness to consider beauty. What kind of frame can be stably worn? Wenzhou Wanrun Glasses Co., Ltd. tells you whether the frame is stable mainly from the following three aspects: nose bracket: plastic bracket that contacts the nose on the frame. When selecting, pay attention to whether the bridge of the nose can be stably supported on the bridge of the nose and will not slide when lowering or shaking the head.

For children with relatively low noses or long eyelashes, try to choose glasses with movable nose pads, because they can be adjusted as needed. Lens ring: The size of the lens ring mainly determines the size of the glasses. If the lens circle exceeds the face, it will be too large. Too large lens ring is easy to wear. If the lens ring is too small, both legs will stretch out. It's too tight to wear comfortably.

Lens leg: suitable for children's glasses. The lens legs should be attached to the face skin, or a little space should be left to prevent children from developing too fast and the glasses are too small. For the adjustable mirror frame, we can adjust the bending point behind the mirror leg to make the wearing more stable; For the mirror frame that cannot be adjusted, as long as the frame size is relatively appropriate, the ear hook should be installed behind the mirror leg. For frames that are too large or too small, even if ear hooks are installed, the effect is not ideal.

There is no doubt that the lighter the frame, the more comfortable it is. For example, the titanium alloy frame and TR90 frame are relatively light at present. In addition to the weight of the frame, the appropriate frame should also be selected according to the child's degree. For the safety and fastness of the frame, children are recommended to wear the full frame. Low degree - it is unnecessary to consider the size of the frame, as long as the size is suitable for children's wear and comfortable.

Medium height number - Must combine frame size and pupil distance. What is the frame size? It refers to the size of the mirror frame marked on the mirror leg. The frame size is expressed as follows: 48 □ 16. The sum of the two numbers before and after the box is 2-4 greater than the pupil distance. We usually choose the frame according to the children's skin color, face shape, personality and other characteristics. However, it should be noted that special diopter, such as high hyperopia, high myopia and high astigmatism, will affect the overall appearance of glasses after processing.

For children with height, we first recommend resin film, and select lenses with different refractive index according to different degrees: low degree (below 3.00D): 1.50 and 1.56 lenses can be selected; Medium degree (3.00-6.00D): 1.56 and 1.60 lenses can be selected; Height (above 6.00D): basically, 1.60 and above lenses should be selected. It should be noted that the lenses for high and far vision (+6.00D or above) are generally recommended to be customized, because they can be made into special lens diameters. In this way, the rear lenses will be thinner and the overall effect will be better. The article comes from the network. If there is infringement or violation, please contact us to delete it.
