First, the structure of the frame
A pair of kids eyeglasses near me frame is usually composed of mirror rings, nose brackets, pile heads and mirror feet and other main parts, in addition to the above parts, there are foot covers, support leaf screws, hinge screws and so on.
1, mirror ring (frame) : the assembly position of the lens, with wire, nylon wire and screws, with grooves or drilling holes to fix the lens, it affects the cutting of the lens and the shape of the glasses.
2, the bridge of the nose: connect the left and right mirror rings or directly with the lens fixed connection, the bridge of the nose is directly placed on the nose, but also through the support of the nose.
3, nasal support: including the support leaf stalk, the support leaf box and the support leaf, the support leaf is in direct contact with the nose, plays the role of supporting and stabilizing the mirror frame. Some moulded plastic frames may not have a holder and a holder box, and the holder is connected to the mirror ring.
4, pile head: the connection of the mirror ring and the mirror foot, generally curved.
5, mirror foot: hook frame on the ear, can be moved, connected with the pile head, plays a fixed mirror ring role.
- Hinge: a joint that connects the pile head and the mirror foot.
- Lock block: tighten the screw to tighten the lock block on both sides of the mirror ring opening, so as to fix the role of the lens.
Second, the size of the frame
Glasses are a standard product, and like clothes and shoes, they come in their own sizes.
The parameters of the size of the glasses are marked on the leg, the bridge of the nose or the label. For example: 52 mouth 20-145, indicating that the frame size is 52mm, the nose bridge size is 20mm, and the leg size is 145mm.
Frame size explanation:
- Frame size: the distance between the inner sides of the mirror ring at the midpoint of the plane vertical line where the frame is located. Generally 33-- 60mm.
2, nose bridge size: the wider distance of the horizontal line where the nose bridge of the mirror frame is located. It is generally 13-- 22mm.
3, the size of the mirror leg: from the center of the hinge to the end of the mirror leg elongation distance, generally 125-- 156mm tungsten carbon plastic steel.
4, frame height: the outer edge of the upper and lower edges of the frame is wider.
5, the outer width of the frame: the distance between the visible area on the left and right sides of the frame, that is, the distance between the frame and the junction of the two mirror legs. The outer width of the frame surface below 128mm is classified as small code, 129mm to 138mm is classified as medium code, and more than 139mm is classified as large code.
6, the inner width of the frame: the distance between the inner legs of the two mirrors 60mm after the plane of the mirror ring. This is just the contact point between the mirror leg and the temple of the human body. If it is too tight or too loose here, it will affect the wearing comfort.
It is recommended that you understand the size of the frame that is suitable for you through the following ways, and it will be more efficient when you choose it in the future.
View the parameters of the glasses (usually marked on the inside of the mirror leg);
If your frame parameters have been worn, you can use a ruler to measure the fitted glasses to get the data;
Try it on at an optician's and make a note of the size that suits you.
