How to do if the glasses frame is crooked?

If the glasses frame is crooked, you can take it to the glasses shop for repair

Cleaning and maintenance

1. Ultrasonic cleaning is used to remove the dirt inside by vibration. This service is available in most optical stores, and is basically free of charge.



2. When the slot of the lens of the full frame glasses frame is dirty, you can unscrew the screw yourself and remove the lens and clean it with a paper towel.



3. If the screw is loose, please take it to the optician in time to tighten it, otherwise the lens will be easily broken on the ground. Do not dispose of it at will.



4. Cosmetics or cosmetic products with chemical ingredients are easy to fade the lens frame. Please use special cloth or paper for glasses to clean it.



5. Most glasses are gently folded from the left foot. If they are folded from the right, the frame itself will be unbalanced and skewed, which will make you uncomfortable after wearing them.


6. In order to give full play to the correct function of glasses, the optical center of the lens should be located at the position suitable for your eyes. Please wear it at the correct position.

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



1. The geometric center size of the eyeglass frame should be close to the distance between the pupils of both eyes (less than 4 to 10 mm is preferred).



Considering that the blank of the lens must be moved to the center and cut before it can be mounted on the spectacle frame and placed in front of your eyes, it is better that the position of the pupil should face the geometric center of the spectacle frame, preferably less than 4-10mm. If the lens moves to a very large center, it may cause prism and other effects, affecting the comfort of wearing glasses.

2. After wearing glasses, ensure that the distance from the lens to the eyeball is about 10mm.



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



3. The included angle between the front face of the glasses and the vertical line of the wearer's face is about 4 °~18 °.



The angle is related to the field of vision. Generally speaking, the upper part of the frame cannot touch the eyebrows, and the lower part cannot touch the face. If the mirror frame cannot reach the required forward tilt angle, it is recommended to find a professional to adjust the nasal stipe or change a pair of mirror frames.



4. The width of the eyeglass bridge is moderate.



Consumers can check the glasses frame by themselves through the following methods: keep the head vertical and looking forward, and the glasses frame can maintain a satisfactory position without any clamping of the legs.



If the nose bridge is too narrow, not only will the lens be too high in front of you, but also the part where the nose bridge contacts the nose will be uncomfortable, and even cause temporary depression of the nose skin tissue; If the nose beam frame is too wide, the lens will fall too low, and it is impossible for the legs to keep the frame in normal position for a long time.



5. The length of glasses legs is moderate.



In principle, the curved part of the mirror leg should be just above the ear fold, but the pressure on the ear fold should be avoided. If the leg length is not enough, the glasses will tilt upward, and the tail of the frame will press into the back of the ear, making the wearer feel uncomfortable; If the length of the leg is too long, when the head is tilted, the tail of the frame will touch the back of the ear, and the glasses will fall down by themselves.



It is worth noting that when trying on the spectacle frame and estimating the length of the leg, the frame should be kept at the correct forward angle on the face. If the forward angle is not taken into account when trying on the spectacle frame, the leg length will be too short if you wear it for a long time.
