Why are titanium glasses so expensive?
Strong and Durable. They are widely used in aerospace technology, jewelry, surgical instruments, and other fields. It is the most progressive material in the eyewear industry. Titanium is a very hard, lightweight metal that is proper for eyeglass frames. With good hardness, high strength, the glasses are not easy to deform. It is not easy to scratch and wear and has good corrosion resistance and plasticity. It has a high melting point, corrosion resistance, and hard electroplating. Titanium can be made into memory metal, which means it can bend and return to its original shape. Hinge is not easy to break, having rust resistance, impact resistance. When it's used in glasses, it fits the bill.If you've ever broken a frame, titanium is possible the best material for you.

Initially, carbon fiber was used in aerospace, energy-related equipment, sports materials, construction, and other fields.

Drivers can wear night-vision goggles
Night-vision goggles can prevent headlights from blinding, add color saturation, and make the field of vision clearer. The normal night vision glasses are golden yellow in color and have a metal coating on the surface. This is the use of diamond high perspective reflection film technology, in the lens to add color and film layer, in order to maximize the brightness of the object being seen. It is to compensate for the light for driving, which makes light pass through your eye. It can increase the three-dimensional sense of objects, making the line of sight more clear, to avoid confusion caused by blinding headlights.
Go to a regular hospital to check your eyes
On the surface, pseudo-myopia is the same as true myopia, that is, looking far away is blurred and near looking clearly. But looking at the essence through the phenomenon, the difference between the two is obvious. The so-called pseudo-myopia is due to frequent incorrect use of the eyes. The ciliary muscles continue to contract and spasm, and they cannot get the rest. And the crystals are also in a state of thickening. In this way, the parallel light from the outside enters the eye, and after the thickened lens chamber is flexed, the focus falls to the front of the retina, and it is naturally unclear to look at things in the distance. During this period, the eyeball has no organic changes. If you can take proper rest and treatment, pay attention to eye hygiene, use your eyes reasonably, and hope to restore normal vision. However, if the false myopia is not corrected and treated in time, it will develop into true myopia over time. There are many ways to treat pseudomyopia, mainly relaxation and adjustment, such as application of cycloplegia, acupuncture, physical therapy, improving the learning environment, paying attention to eye hygiene, and doing eye exercises. If you suspect false myopia, you should go to the hospital for an eye examination as soon as possible.

People with round faces should try to avoid round frames, which can make your face look fatter. You can choose a square frame, having a decorated effect, and can make a person look more energetic. Circular lenses are recommended for square faces. Rectangular faces are also suitable for circular lenses. There are not too many restrictions on the choice of lenses for heart-shaped faces. Circular or square pieces are very appropriate, but you can choose slightly larger frames to add momentum and can create a retro sense.
