How to repair rimless glasses?
First, insert the wire into a small hole in the glasses near the bridge. Pass it in and out near the bridge, then repeat the process on the other side near the temple. Once you have the thread locked, you can place the lens. Insert it into the frame and place the wire in the built-in groove. Tighten the wire so it holds the lens perfectly, then trim it to the left. Reinsert the lens into the rimless glasses. Do not try to force it back in. The best way is to cut the wires completely and replace them with new ones. Use the same process as replacing wires. To prevent glasses from popping out, tighten the wires regularly.
The keyhole bridge is different from an ordinary bridge.
The common bridge is designed to span the tip of the nose like a saddle. The two sides are evenly distributed along a wider area for a more even distribution of the weight of the frame and lens. A common bridge is the most effective way to shorten and reduce the shape of the nose. Especially when the upper margin of the frame is aligned with the eyebrow line or just below the eyebrow line, the overall structure of the face is more balanced. Both kinds of bridge designs have been widely used. Lighter colors, like clear crystal or pale yellow, will reduce the effect of keyhole bridges on the nose.
The keyhole design touches two sharp points of the nose bridge eliminating pressure from the top of the nose. This style makes a bold fashion statement suitable for both men and women. Athletic designs with comfortable details make this collection the first choice for everyday wear.

Blue light in natural light
Blue light is not the unique light emitted by electronic products, but the visible light that exists in natural light, usually with a wavelength of about 400-500nm. The blue light in the entire waveband can be subdivided into two parts. One part will cause optical damage to the retina of the eye and accelerate the oxidative senescence of cells in the macular area of the retina. Usually, the wavelength of this part of blue light is between 415-450nm, and its damage to the eyes is gradually accumulated and formed. There is also a part of blue light that is beneficial to our human body, that is, blue light with a wavelength of about 480nm. It can adjust biological rhythms and is helpful for sleep, mood, and memory. In addition, experiments have confirmed that daily outdoor activities in the sun can effectively prevent the occurrence of myopia, and short-wavelength blue light may play an important role.
Choose the frame according to the hairstyle
If there are bangs, the upper edge of the frame should avoid contact with hair. If it is curly hair, it should be noted that the frame should not be too large so that the frame edge contacts the hair.
