The weight difference between pure titanium frames and titanium frames
Titanium frames are slightly heavier than pure titanium frames, but they are both high-quality materials, so they are more comfortable on the outside. The specific gravity of pure titanium is generally 4.5, while titanium alloy is 8.9, which means the material is equivalent to half of the titanium alloy. So the frames are lighter in your hand.
Cosmetic Contact Lenses & Chromatic Contact Lenses
We are used to referring to chromatic contact lenses as beautiful contact lenses. In fact, beautiful contact lenses are a registered trademark of Johnson & Johnson in 2007. It is the name of a product series of Johnson & Johnson. Not all chromatic contact lenses are called beautiful contact lenses. Regular contact lenses can have complications if they are not properly worn, and these can also be seen in chromatic contact lenses. But because the color piece was much a layer of pigment, if the quality is not up to standard, there will be greater safety hidden trouble.

What Should Be Considered When Buying Blue Light Glasses?
Be wary of “eye protection” claims. Some businesses advocate their anti-blue light products how miraculous.
Do not try the lens from the unknown lens manufacturer or lens factory. A professional lens factory needs more than ten years or even decades of accumulation, so do not be blinded by dazzling pictures and brand image.
Superior properties of titanium alloy
The specific strength (strength/density) of titanium alloy is far higher than other metal structural materials, which can produce high unit strength, good rigidity parts.The engine parts, frames, fasteners, and landing gear are all made of titanium.It can still maintain the demanded strength at medium temperature and can work for a long time at 450 ~ 500℃.
Clean Glasses Properly
If the glasses are dirty, don't just wipe them with other cloth. If you use some hard cloth to wipe, it is easy to cause scratches in the lens. Generally speaking, the following cleaning methods are all feasible.
1. Use neutral or alkaline cleaning agent. Remember, toothpaste cannot be used as a substitute for the cleaning agent for spectacle lenses. General optical shops also sell lens cleaners in small bottles, which are easy to carry.
2. Go to the optical shop for professional ultrasonic cleaning. General optical shops provide free cleaning services. The ultrasonic cleaning machine can fully clean every gap and groove of the glasses.
3. Rinse the lens with tap water. Hold the frame in one hand and the cleaner in the other hand. Rub it slowly against the lens, and then rinse it off with clean water. Then wipe it with a glasses cloth or let it dry naturally.
In addition to the glasses cannot be cleaned with alcohol, you should also pay attention to their placement for daily maintenance. Try to avoid putting it under high temperature, and avoid oily, smoke, etc. If you don't use them, put them in the glasses case.
Advantages of Plastic Frames
Plastic is usually called a plate, having no skin allergies. The price is relatively cheap. Colors and styles are diverse. The color is rich, rich in shape.

TR material has high transparency. With high flexibility, it can meet the needs of different sizes. Plate material surface hardness is high. They need no surface treatment, having noble texture, wear-resisting. Suitable comfort change can be made according to different face sizes.
