How to choose blue light blocking glasses?
Nowadays, electronic products such as mobile phones and computers have become indispensable tools in our lives. While these high-tech products bring us convenience and fun, they also bring symptoms such as eye fatigue and myopia. Subsequently, blue light blocking glasses have also received everyone's attention. Anti-blue glasses are only suitable for people who use electronic products for a long time, not for people who are visually fatigued. Exposure to such unnaturally strong blue light for a long time every day, especially for teenagers and children, needs to pay more attention to the prevention of blue light. So, how to choose suitable blue light blocking glasses for kids?
Anti-blue light is necessary, but not all blue light can be filtered out, because blue light will interfere with the body's melatonin secretion after being over-filtered, thereby affecting sleep. Therefore, when choosing blue light blocking glasses, you should choose appropriately according to your own eyes.
For how to choose anti-blue glasses, consumers can distinguish from the color of the lenses. Generally speaking, a lens with a yellow color will have the effect of blocking blue light. But too dark lenses will affect the contrast sensitivity. Therefore, it is recommended that consumers choose moderately. In addition, consumers should also pay attention to whether the glasses products (lenses, frames) have conformity marks, etc. It is best to choose professional and well-known glasses shops to match glasses.
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.

What are the causes of lens damage?
When the force area of the lens is small, the impact resistance of the lens is worse. When subjected to the impact of external forces, the lens will naturally be squeezed and cause breakage.
In particular, some lenses with low degrees and high refractive index are possible to cause this phenomenon. When the frame fell from a height due to wrong placement, there is a collision between the edge of the lens and the ground or hard objects. It will produce a broken or collapsed edge. In the process of the lens falling from high, the impact force is larger, and the stress point is smaller. When the glasses are falling, the upper edge of the lens, the convex groove of the upper frame, squeezes against the lens. The middle part of the upper half is easy to cause edge collapse. In the process of processing the template, the template is not accurate, so that the glasses side and the frame can not be uniform fusion, and the force of the lens is uneven. It will be easy to lead to greater stress in some parts, resulting in edge collapse.

Benefits of Saddle Bridge Glasses.
The most common type of plastic bridge is called a saddle bridge. The style is very comfortable because it distributes the weight of the glasses over a larger area rather than focusing on smaller points, like adjustable nose pads. Saddles are known to cost less to repair because they have fewer moving parts and are possible to maintain their fitness. There is now a new saddle bridge-type transparent silicone cushion for a screw-type nose pad. It is made of medical-grade soft silicone. It can be bent and is very soft. To fit the curve of the nose, a plastic frame with a saddle or keyhole bridge can slip off the nose without proper support. Silicone is a soft and elastic material that can be formed according to the contour and shape of the nose.
Which face types are suitable for rimless glasses?
Rimless glasses are mainly suitable for round faces, heart-shaped faces, square faces, and other most face shapes. Rimless frames are designed to be light, hence, they ease the wearer's stress, increasing comfort, and providing a wide view. Rimless glasses suit most face types, suitable for people who are short-sighted within 600 degrees. If the degrees are too high, you should not wear rimless glasses. When the degrees are too high, the lens will be suitable for thickening, so rimless glasses will show bloated.
