The rimless glasses are not limited by the frame, and the wide field of view, beautiful appearance and light weight are favored by the glasses family. However, after wearing the rimless glasses for a period of time, the lack of beauty will be revealed - the screws at the punching holes are easy to loose, and the wearers should often add after-sales service - tightening the screws; the store will suffer intangible losses - quality and reputation influences. In fact, this problem is well solved. When you pay more attention to the fitting, you can eliminate the trouble.
1. Pay attention when you are down.
There are usually two types of rimless glasses, one is the outer mirror, that is, the metal beam of the mirror beam and the temple is located on the front surface of the lens; the other is the inner mirror, that is, the metal hole of the mirror beam and the temple is located on the back surface of the lens. Grinding lens should have a certain emphasis when it is inverted. Whether it is an external mirror or an internal mirror, first use a marker to point the punching point. When the edge is inverted, just touch the lens with the frame and the temple elbow. If you have more than one side, the range should not exceed the metal coverage. When the other parts are inverted, gently rub off some of them. The edge of the lens is not sharp. It should not be too heavy. Otherwise, it will interfere with the reflected light and affect the appearance. .
2. Pay attention when punching holes.
After the inverted edge is changed, compare the punching point with or without the shift, and then click the punching point again. It is best to use the bench drill. When punching the outer mirror, it should be made inward from the outer surface of the lens, and inclined slightly toward the optical center, so that the surface of the nut contacts the inner surface of the lens. When the hole position is slightly adjusted at the initial installation, the plate and the frame can be closely connected, and the screw is not easy to loose. The inner mirror is punched outward from the positioning point of the inner surface of the lens, and the side is slightly inclined toward the optical center. Some customers like to use the mirror beam and temple of the A frame, and then use the B frame, the combination of the two. We know that each type of glasses designed by the manufacturer is considered from the overall perspective, and the combination of the two sub-mirrors increases the difficulty of fitting. To ensure that the beauty is not lost after assembly, the hole position of the mirror beam should be considered first in the fitting. To ensure the symmetry and balance of the upper part of the left and right pieces, when the hole position of the temple is determined, the left and right legs are closed and pinched, and the pile head is punched. Bend to the lens (the inner mirror is under the lens), after determining the balance is correct, use the marker to clear the hole position (should have an assistant to cooperate), punch the hole. The number of times the combination glasses are fitted can help the customer to design a different type of film according to their personal preferences. The fitting is always in the mind, and the special requirements of the customer can be realized.
3. Pay attention to the screws.
The length of the nose screw should be chosen to be shorter than the inner surface of the lens. The inner mirror should not be padded on the outer surface of the lens. The resin sheet has a certain elasticity. After the four screw nuts are installed, the temples are closed. After adjusting the adjustment balance, do not rush to tighten, fine-tune the balance, and then tighten. Nuts. After shaping, lightly tap 502 glue on the nut, and then dry it, then you're done. This method of rimless glasses has the effect of wearing three years without loosening.
