Beta titanium

β titanium refers to a particle titanium material that is completed by delayed cooling at the zero bound point state of titanium and does not belong to the alloy. Practical applications will often be processed into alloys to increase their applicability. Although the purity of β titanium is not comparable to pure titanium, its strength, fatigue resistance, and environmental corrosion resistance are better than pure titanium. It has higher strength than pure titanium and other titanium alloys, and the corrosion resistance is stronger and has better elasticity, It is not easy to deform, and is lighter.



Difference Between Driving Glasses And Night Vision Goggles

The use of driving glasses and night vision glasses is different. When sunlight is projected on the road or water, it directly stimulates the eyes, making them feel dizzy, tired, and unable to see for a long time. Especially when you are driving a car, doing outdoor entertainment activities, it will not only affect our work and entertainment mood, and even affect our judgment of the image and cause danger. The polarized driving glasses can be used during driving, fishing, skiing, rain, etc. when there is a strong reflection of strong light. Night vision goggles are usually used at night and have great applications in transportation, the military, and other fields. A large amount of night vision equipment has been used as a winning strategy to dominate night combat. Combining night vision technology with weapons and equipment will greatly improve the effectiveness of weapons and equipment in getting information, conducting strikes, commanding troops, and coordinating operations at night and in bad weather.

Wear blue light glasses before bed.

Because blue light can have a huge impact on your sleep cycle, these glasses are pretty important before bed. So, putting on blue light glasses before you go to bed can help increase melatonin, which in turn helps you get a good night's sleep. Sleep glasses display a wider range of blue light, which naturally helps you sleep better and triples melatonin production. They have a slight lens color because they target a wider range of light, but are best for sleeping. In addition to sleep glasses, there are nearly transparent optical glasses that filter out blue light levels to help treat digital eye strain, which is made up of headaches, blurred vision, and eye strain.


What material is the lens coating used?

The anti-reflection film material of glass lenses is usually magnesium fluoride. Because the coating process of magnesium fluoride must be carried out at more than 200℃, otherwise it cannot be attached to the surface of the lens. The resin sheet is not used. Since the 1990s, with the development of vacuum coating technology, the combined effect of film and lens has been improved. At the same time, high purity metal oxide materials like titanium oxide and zirconia can be deposited on the surface of the resin sheet through the evaporation process to achieve a good anti-reflection effect.

Why choose an acetate frame?

(1) Lightweight and comfort

As one of the daily necessities, the lightweight acetate frame will not bring a heavy burden to the bridge of the nose. Even if you need to wear glasses all day, you will not feel too much discomfort.

(2) Durability

This is the key factor that makes acetate frames stand out from traditional plastics or other materials. Acetate frames are made by cutting, molding and polishing multiple pieces of material, which makes them as strong as metal and ideal for eyeglass frames.

(3) Various design

The cellulose acetate spectacle frame design is the most fashionable. The surface layer of the traditional plastic frame is usually sprayed with colors and patterns. It may have a nice design or color. But because it is the only surface, daily use will cause its surface color and pattern to fade. After a year or even a few months, their appearance may not be as good as before. Unlike plastic spectacle frames, acetate makes the design easier to retain. The acetate fiber sheet can be designed with colorful patterns, different layers, and many colors. The embedded design can maintain its characteristics more effectively without spraying or painting.

Acetate is comfortable, weight-light and fashionable, and meets all your needs. Therefore, it can be said to be the best material for making spectacle frames. Therefore, the next time you decide to buy a new spectacle frame, please consider using a spectacle frame made of acetate.
