Adjust the nose pad

The height of the nose pad is adjusted by first holding the glasses with one hand and holding the nose pad with pliers with the other. Then the pliers are lifted up and the nose pad is moved down until the glasses are in the correct position on the face. The asymmetrical adjustment method is to first hold the frame of the eyeglasses with one hand, the other hand clamps the nasal plate with pliers. Then twist it in the direction of the correct tray position so that the surface of the tray is in contact with the two sides of the nose. Wrap one side of the lens of the glasses to be operated with a cloth first to prevent the screwdriver from slipping and scraping the lens during the operation. Don't scratch your glasses by adjusting your nose pad.

Replace the nose pad on your glasses

Remove the screws clockwise and use a toothpick to remove the things left of the broken pads so that the new one can be installed. The next step is to fix the nose pad that we just removed from it. Hold the glasses and then the hole for the nose pad is up, then place the nose pad in and press it with your finger. Then you can see that the round hole in the nose pad overlays with the round hole in that part, and at this time, you can turn the screws. When you finally turn it, you usually turn it three times to hold the nose rest in place. Often, the nose pad can be swung back and forth after installation. This is to match the different shapes of our noses.


The origin of modern eyeglasses

The origins of modern glasses can be traced back more than 1,000 years. In the Middle Ages, the reading stones used by monks were glass spheres, sometimes filled with water and placed on objects to magnify them.Glassblowers in Italy created reading stones, similar to modern hand-held magnifying glasses. The reading stone can be placed on the wearer's nose or in front of the face. Later, Spanish craftsmen built the first cobra-framed temple in the 17th century. They tie ribbons or strings to the frames and tie them around the user's ear.

In the 18th century, Edward Scarlett created the first wearable glasses, providing more comfort for eyewear wearers. These early glasses had glass lenses embedded in heavy frames made of wood, lead, or copper. Natural materials of leather, bone, and horn were later used to make the frames. In the early seventeenth century, lighter steel frames were invented. As eyewear continued to evolve and prescription accuracy improved, the trend for eyewear to become more fashionable began. In the 18th century, bifocal lenses appeared, making it possible to correct upper myopia and lower presbyopia. Later glasses were designed to be fixed by a ribbon or by applying pressure to the bridge of the nose. In the 1980s, plastic lenses were introduced, providing a more durable alternative to glass lenses. Ultimately, the glasses used today are the result of centuries of technological and intellectual advances.



Progressive multifocal glasses are more powerful.

On the premise of the dual vision correction effect, the progressive lens has more stable and complete functions. They provide lasting clear vision. Because the added value is continuously and slowly increased in the related area, the wearer can get a lasting clear vision from the far place to the near place through the progressive glasses. The appearance is better than that of bifocal and trifocal lenses, and there is no subplate dividing line.


What are acetate glasses?

Acetate spectacle frames are the most common spectacle frames on the market. It has a light texture and good gloss, which is very popular among young men and women. Acetate frames are lighter and generally considered to be better than plastic frames. Acetate fiberboard is known for its Hypo-Allergenic, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions. However, you will find that acetate frames are usually more expensive than ordinary plastic frames. So what is the reason?

Acetate is one of the first synthetic fibers. It was not used to make glasses until the late 1940s. The higher the quality of acetate, the better the gloss and transparency. Not easy to burn is one of the biggest characteristics of acetate fiber. Also because of the non-combustibility of acetate fiber, this material can hardly be affected by ultraviolet radiation to change color, and can better maintain the gloss of the spectacle frame. Moreover, it is light and hard, and it is not easy to deform.
