How did the eyeglasses market develop?

With the discovery of clear glass paste in the 14th century, lenses became cheaper and easier to sell outside Venice. In the 15th century, the invention of the printing press made it easier to read, which greatly increased the demand for glasses. By the 16th century, frames were made of luxurious materials such as horn, leather, and whalebone. They used real turtle shells. The artificial plastic celluloid was later used to make frames that had never been seen before. In the 1950s, glasses became more popular than ever. Even today, glasses are considered one of the best fashion accessories. Different colors and styles of frames can be made according to the face shape. New technologies for lenses, contact lenses, and even frame materials continue to evolve year after year.

The semi-rimless glasses are designed to make the wearer look the smartest. They are much better than rimmed glasses because they make you look more creative.


Disadvantages of Progressive Lens

There are deformation areas under the left and right sides of the lens, which make the image blurry and irregular. It takes 1-3 weeks to get used to it. In addition, it has a narrower field of view in the near and middle distances, and long-term concentration on the narrow focal point can easily make the eyes tired. Suitable for people who need to alternate between distant, medium, and near vision.

However, with the development of science and technology, more and more progressive multifocal glasses have emerged that have a wider field of view, more comfortable wearing, and better meet the needs of eyes. Nowadays, the use rate of progressive lenses among middle-aged and elderly people abroad is quite high. Single-lens and double-lens reading glasses are gradually being replaced by progressive multifocal glasses.

The plate frame is also suitable for people with a high number of heights because the frame is larger and can withstand a high number of lenses.


Are night driving glasses good?

The color of night driving glasses can be selected from yellow to amber. Yellow lenses will reduce the light entering the eyes and reduce visibility. At night, this can be harmful. The lens filters out a lot of glare, but also filters out other visible light, making it difficult to see objects in dim or dark conditions.

Some people who wear night driving glasses say that they are more capable of seeing things at night. However, related test studies have shown that driving glasses at night does not improve night vision, nor can it help drivers see pedestrians faster than when they are not wearing glasses. A small study in 2019 showed that night driving glasses actually slow down the visual reflex by a fraction of a second, making night vision worse. So don't try to improve the safety of driving at night by wearing driving glasses with this kind of yellow lenses.
