What Is a Mirror Mount?

The spectacle frame is an important part of the glasses, which mainly plays the role of supporting the spectacle lens, and the beautiful-looking spectacle frame can also play a beautiful role. Materials are mainly metal, plastic or resin, natural materials, etc. According to style, it can be divided into full frame, half frame, frameless and other types.

Glasses frame

Glasses frame is

A pair of spectacle frames is usually composed of the main parts such as a lens ring, a nose pad, a pile head, and a temple. In addition to the above components, there are foot covers, bracket leaves screws, hinge screws, and the like.

1. Mirror ring (frame): The lens assembly position uses metal wire, nylon wire and screws to fix the lens by means of grooves or holes, which affects the cutting of the lens and the shape of the glasses.

2. Nasal bridge: Connect the left and right lens circles or directly connect with the lens. The bridge of the nose is directly placed on the nose or supported by the stipule.

3. Nasal support: including stipule stalk, stipule box and stipule. The stipule is in direct contact with the nose and plays a role of supporting and stabilizing the frame. Some cast plastic frames can be without stalk and stalk box, and the stalk is connected with the mirror ring.

4, pile head: the junction of the mirror ring and the mirror foot, generally curved.

5. Mirror feet: The hook frame is on the ear, which can be moved and connected to the pile head, and plays a role of fixed mirror circle.

6. Hinge: A joint connecting the pile head and the temple.

7. Locking block: Tighten the screws to fasten the locking blocks on both sides of the opening of the lens ring, thereby fixing the function of the lens.

1. Full frame: it is the most commonly used type of frame, which is characterized by strong, easy to shape and can cover part of the lens thickness.

2. Nylon wire frame: Use a very thin nylon wire as part of the frame edge. The lower edge of the lens is flattened by special grinding. The style is very light, giving it a light and chic feel, and it is also relatively firm.

3, no frame: This type of frame does not have a mirror ring, only a metal nose bridge and metal temples, the lens and the nose bridge and temples are directly connected by screws, usually to punch holes in the lens. Frameless is lighter and more chic than ordinary frames, but slightly weaker.

4. Combination frame: There are two sets of lenses at the front frame, one of which can be turned up, usually for indoor and outdoor use.

5, folding frame: the frame can be folded into 40% or 60%, mostly for reading mirrors.

6. Half-frame frame: The half-frame is made of a very thin nylon wire as part of the frame edge, which is characterized by light weight, giving people a feeling of lightness and chic, but also relatively firm.

7. Eyebrow frame: The eyebrow frame is similar to the half-frame frame. The upper half frame only has a loop wire similar to the eyebrows. A thin nylon wire is used as the lower frame edge, which is more fashionable.

Made of titanium

A good pair of frames should be stable, safe, reliable, and harmless to the skin. They should be lightweight, strong, and not deformed. For customers, they often purchase from the perspective of the practicality of the frame.

Choose a frame based on your vision and use

Wearing time

If the glasses are used for a long time, you can relax other conditions and choose a lighter frame to reduce wearing fatigue. If the spectacles are worn only when the eyes are concentrated, such as reading and watching TV, you can choose the frames completely according to your needs.

Vision condition

Those with high myopic power should not choose half-frame and frameless frames, because the thicker lens thickness is not beautiful and easy to damage. Those with higher astigmatism power should not choose frameless frames, because the lens with frameless frames will have the problem of astigmatism axis displacement after long-term use, which will cause deformation of the object being viewed.

Specific needs

If the purpose of the glasses is largely to match the needs of the image and the occasion. At the same time, under the condition that the vision condition does not restrict the frame high, you can choose according to your specific needs. And those who are often engaged in large-scale physical activities and sports should choose a frame with a more compact frame and plastic sheet material to reduce the chance of spectacles being damaged by accidental impact. At the same time, we also recommend wearing contact lenses during exercise.

People who are busy with work and frequent business trips can choose frames made of memory materials to avoid deformation and damage caused by frequent picking up, littering, or being damaged due to improper placement when riding trains or airplanes. Crushed.

Four-step selection of high-quality frames

1.Style-see fashion

With the personalization of consumer demand, the fashion features of glasses are being valued more and more. The choice of style should be combined with the current popular colors and elements. At the same time, referring to the corresponding style to decide what material to choose the frame will be targeted.

2. On the color-see the depth

Place the glasses flat in front of your eyes, and observe the difference in shade of the temple color under the same light intensity. Sometimes, due to processing errors, the color of the temples may be asymmetric.

3. Technically-see details

The craftsmanship is the quality guarantee of the frames, and the quality of a pair of frames is often reflected in the details.

(1) Pay close attention to the welding points of metal frames to see if there are cracks. Due to the thermal effect during welding, the stress structure of the material is changed, or fracture occurs when it is subjected to stress due to virtual welding or material fatigue.

(2) Whether the two temples are flat. Place the frame flat on the table to see if the contact points are suspended. If there is a situation where one side is high and the other side is low, it is necessary to require professionals to adjust the temples to achieve the effect of symmetrical left and right balance and up and down.

(3) Pay attention to whether the stalk of the frame is symmetrical on both sides and whether the fixation is safe.

(4) For metal frames, you can use your nails to see if there are any scratches on the painted surface. For the frame of plastic sheet, carefully observe the surface for plastic particles and rough.

(5) Open and close the temples and feel the elasticity. It is generally believed that the view that the tighter the better is wrong, which means that the screw is not sufficiently lubricated, which easily causes the temples to be injured, and too loose is not good. It may be caused by the screw not being tightened. Moderate tightness is best.

4. On the logo-see the materials

Two metals, gold and titanium, are precious metals, so frames containing these two materials will have corresponding markings on the temple legs:

(1) GF / GP: GF is a gold-clad frame, that is, a frame that is made by welding thin gold sheets on other metal substrates and rolled; GP is a gold-plated frame, that is, gold plated on other metals by electroplating Frame surface.

(2) Ti-P / Ti-C: Ti is a mark containing titanium materials, Ti-P stands for pure titanium, and Ti-C stands for titanium alloy.

At the same time, there are rules for frame materials: manufacturers cannot use frames made of materials that cause adverse irritation due to the contact of the frame with the skin. Both metal and non-metallic materials need to undergo color treatment before there can be various color frames on the market. Therefore, when we buy a frame, we should pay more attention to it when we find that it smells strange.

5.Optical and metrological requirements

Optical and metrological specifications of spectacle frames are very important for the comfort of consumers wearing glasses. The selection of frames must meet the optical and metrological requirements:

(1). The geometric center of the spectacle frame should preferably be close to the pupil distance of both eyes (preferably less than 4 to 10 mm).

Considering that the blank of the lens must pass through the center cut edge before it can be mounted on the eyeglass frame, it is best to position the pupil directly facing the geometric center of the eyeglass frame, preferably less than 4-10 mm. If the lens shift center is very large, it may cause effects such as prisms and affect the comfort of wearing glasses .

(2). Make sure the distance from the lens to the eyeball is about 10mm after wearing the lens.

If the lens is too far away from the eye, not only will the optical effect change, but the wearer will also see the outside of the lens, which will cause difficulty in positioning. If the lens is too close to the eye, the eyelashes will touch the lens, which will not only easily cause lens blur, but also cause irritation. Therefore, it is best to ensure that the distance from the lens to the eyeball is about 10mm after wearing the lens.

(3). The included angle between the front mirror surface of the glasses and the vertical line of the face of the wearer is about 4 ° to 18 °.

The size of the angle is related to the field of view. Generally, the upper part of the frame cannot touch the eyebrows and the lower part cannot touch the face. If the frame cannot reach the required forward tilt angle, it is recommended to find a professional to adjust the nose paddle or change a pair of frames.

(4). The width of the nasal bridge is moderate.

Consumers can check by themselves when selecting the spectacle frame by keeping the head vertical and looking forward, and the frame can maintain a satisfactory position without any clamping of the temple.

If the bridge of the nose is too narrow, not only the lens will be too high in front of the eyes, but also the area where the bridge of the nose touches the nose will be uncomfortable, or even cause the nose skin tissue to temporarily sag; if the bridge of the nose is too wide, the lens will fall too low. It is impossible for the legs to hold the spectacle frame in a normal position for a long time.

(5). The temple length is moderate.

In principle, the curved part of the temple should be just above the ear folds, but you should avoid putting pressure on the ear folds. If the length of the temples is not enough, the glasses will tilt upwards, and the tail of the spectacle frame will be pushed into the back of the ear, making the wearer uncomfortable. If the length of the temples is too long, when the head is tilted, the tail of the spectacles will contact the back of the ears, and the glasses will Fall on its own.

It is worth noting that when trying on the spectacle frame and estimating the length of the temple, the frame should be kept at the correct forward tilt angle on the face. If the forward tilt angle is not considered when trying on, the length of the temple will be felt for a long time too short.

(6). The deeper the negative diopter (commonly known as myopia), the smaller the lens circle is.

(7). Generally speaking,

1. Use ultrasonic cleaning to remove the dirt inside by vibration. Generally, optical shops have this service, which is basically free.
2. When the lens slot of the full-frame spectacle frame is relatively dirty, you can unscrew the screws yourself, remove the lens and wipe it with a paper towel.
3. If the screws are loose, please take them to the optician's store to tighten them in time, otherwise the lenses will easily fall to the ground and break. Do not dispose at random 4. Cosmetics or cosmetic products with chemical ingredients, etc., will easily discolor the frames, please wipe with a cloth or paper for glasses.
5. Most of the glasses are gently folded from the left temple first. If you fold it from the right first, it will cause the frame itself to be unbalanced and skewed, which will make you uncomfortable after wearing it.
6, in order to play the correct function of the glasses, the optical center of the lens is made to suit your eye parts, please wear it in the correct position.
7, with one hand to take glasses, easy to deform the frame. If the frame is deformed, you should find a local optician to adjust the angle. Do not adjust it yourself, otherwise the lens will be broken and the frame will be damaged.
8. Do not leave it in the place where the sun is easy to shine for a long time, because the frame is easy to fade under the light and pyrolysis. Especially the plate frame, please do nt put it on the dashboard of the car. 9. Wipe dry with glasses. Do not touch the lens with hard objects, do not rub the lens with your fingers, please wipe the lens with a clean lens cloth to reduce lens wear.
10. Do not lower the convex side of the lens. When not in use, put it in the eye box as much as possible. If the glasses are not worn, please wrap the glasses with a mirror cloth and put them in the box to avoid damage.

11. Please rush beside infants and children when resting.
