2, which choice for glasses lens?
Myopia glasses lens can be roughly divided into four major categories: resins, glass sheets, PC tablets and special lenses.
2.1 Resin Material:
The lens is light, more comfortable, and impact resistance is not easy to break. In addition, the thermal conductivity of the lens is low, preventing the fog from appearing in the lens, and is more suitable for students;
2.2 Glass Slice:
High sharpness, high hardness, scratch resistance, but more heavy;
2.3PC tablets:
Toughness, not easily broken, so known as safety lenses, more patient use only patients left;
2.4 Special lenses:
Many advantages to meet more special needs of people.
3, how to choose children’s glasses (rack)?
The mirror frame of young children must be comfortable, safe, sturdy, and attractive, it is best to cooperate with children’s face, age, and consider the activities of children (quiet or good).
3.1
Big appropriate:

Among them, most of the child’s nose is relatively low, the mirror hose is high or the tuitionable active bracket, which can avoid the frame to be attached to the face or even touch the eyelashes, affect the use of the glasses.
In addition, try not to choose a frame where the shadow and the dead angle of the line, also avoid too much frame or too long hanging angle, so that the child has enough sight field.

Material light
Children use glasses, first consider the weight. However, children with high degree, try to avoid ultra-light detachable frames, so as not to cause problems such as glasses and easy to slip in the baby wear.

Most children are naughty and moving, and the extraction of the glasses is not careless. Therefore, it is necessary to consider when the glasses frame is selected.
Among them, the silicone glasses frame is soft (no face), which is preferably chemical (not easy to react with other solvents), and the thermal stability is good (at a short time, no deformation), high mechanical strength (not easy to deform, and There is a super recovery role), non-toxic and no side effects (not easy to cause skin allergy), light material (no obvious indentation, more comfortable), is the children’s glasses frame.
In addition, titanium has both high hardness and super-elasticity, it is not easy to damage, but the value is more expensive, and there are more than 10,000; the mirror-free contact point or a 1000-degree child is used to increase the use of the frame. Period and the potential danger caused by accidental breaks to children is also a good choice.
* The age of young children is suitable for use in elastic ring (sports belt) to detain the frame after the two ear.
