How do you choose a pair of frames that suit you
For myopic friends, every time you go to the glasses shop to choose glasses frame is a very headache problem, it is difficult to choose a pair of glasses suitable for their own, that today teach you how to choose a pair of glasses suitable for their own frame.
Step 1: Choose the frame size
1, look at the degree: the myopia lens is a concave lens, beside the thick middle thin, the higher the degree, the thicker the lens, so the myopia degree is relatively high people do not recommend to choose a large frame, not beautiful, but also relatively heavy, it is recommended to choose a small frame.
2, look at the face: generally speaking, people with a wide face should not use small and narrow frames, long thin face should not use wide frames, if you are a standard oval face, then you can choose any frame type glasses.
Step 2: Choose the frame color
1, white skin color: choose light color frame, such as soft pink, gold and silver;
2, Darker skin: Choose darker frames, such as red, black or tortoiseshell.
3, Yellow skin color: avoid yellow frames and use light colors such as pink, coffee red, silver and white;
4, color red: avoid red frame, can choose gray, light green, blue frame, etc.
Step 3: Choose the frame type
1, Full-frame frame: there is a complete mirror ring to wrap the lens. It is suitable for athletes and children to wear. Because the surrounding of the lens is completely protected by the lens ring, it is suitable for the lens with various refractive parameters.
2, half frame frame: the upper part of the mirror ring is made of metal or plastic materials, and slotted inside, inlaid nylon wire, the lower part of the mirror ring is made of a very thin nylon wire (wire drawing) as the lower part of the mirror ring. Because the lower part of the lens is not blocked by the lens circle, and the thick edge of the lens will affect the appearance, so the degree is too high to choose this kind of frame.
3, frameless frame: there is no mirror ring, only the metal nose bridge and metal foot of the mirror, the lens and the nose bridge and foot of the mirror are directly connected by screws, generally to punch holes on the lens. No frame is more lightweight and chic than the ordinary frame, but the general strength is slightly worse than the full frame. It is not recommended to match this kind of frame for children. The various joints of the frame are easy to loosen, the screw length is limited, and the degree is too high.
4, Combination frame: there are two groups of lenses in the front frame of the combination frame, one of which can be turned up, usually for indoor and outdoor use. The common ones are sunglasses clips, or 3D glasses clips. The downside is that it's hard to find clips the same size as the frames, unless you buy a whole set.
5, Folding frame: the frame can generally be folded at the bridge of the nose and the leg of the mirror to reduce the space occupied by the frame when stored or carried; This kind of frame is generally used for reading glasses. Easy to grind the lens, easy to loosen the connection.
Step 4: choose the frame material
1, plastic mirror frame: mainly divided into injection frame and plate frame two categories. The injection molding frame is light in weight, easy to process, good molding, but easy to deform, poor tensile and compressive strength; The plate frame has bright color, good tensile and compressive strength, but the manufacturing process is more complex.
2, metal mirror frame: its characteristics are: strong, lightweight, beautiful, novel style, variety. Most are alloy, and some may fade depending on the plating process. In addition, there are pure titanium frames, as well as memory alloy frames, which are allergic, durable and corrosion resistant.
3, mixed material frame: mostly made of metal and plastic mixture. Combining the advantages of plastic and metal, achieve beautiful and light, majority is frame plastic, metal mirror leg, more popular over the last two years.
4, natural material frame: common tortoiseshell, wood and animal horns, etc. It is more ornamental than practical, hawksbill is easy to break, wood is easy to rot, and rough wood frame is easy to wear the skin. The killing of hawksbill turtles is now prohibited and relatively rare.
Step 5: Try it on
1, Comfort: The glasses frame needs to feel comfortable after wearing, without pressing the ears, nose or temples, and will not be too loose.
2, the eye distance, as the name implies, is the distance between the lens and the eye, usually 12MM. If the eyes are too far apart, people with myopia may not see clearly, and people with hyperopia may have too high a diopter. The opposite is true when the eyes are too close together. Had better choose the mirror frame that has metallic nose to hold, can adjust height.
3, in the range of choice, their favorite is the most important.
Above IS TO CHOOSE the five steps of glasses frame, a suitable glasses frame can also help control myopia. Ordinary myopia patients should be replaced every two years commonly myopia glasses: one is the "update", 2 it is to adjust the degree.
