Recognize the identity

First of all, we should identify the logo of the pure titanium glasses frame. Usually, pure titanium glasses frame is on the supporting piece of the frame, and the inside of the temples is pure titanium.When online glasses need glasses retailers provide detailed pictures, to check if there is pure titanium.Usually, pure titanium frames are marked with 100% TITANIUM or PURE TITANIUM on the temples or lens.BetaTitanium stands are labeled BetaTitanium or β Titanium, which varies slightly from manufacturer to manufacturer.


About Plastic Frames

It is usually divided into thermoplastic plastics and thermosetting plastics. Thermoplastics can be reworked under heat. Thermosetting plastics cannot. The plastic frame is usually made of nylon or composite material. Although it is a thermoplastic material, at regular temperature will not become soft. The plastics used to make frames are not always thermoplastic, but they can almost always be softened by heating. Thermosetting plastics are usually used only for small parts.



For collection

Glasses' material and styles are constantly updated. It is more and more light and more beautiful. Early glasses may have become antiques. You might as well collect your retired glasses according to the time and story, and attach the tragic history of the glasses. Perhaps many years later today will become a beautiful memory. You might as well try the nostalgic and literary style.

What Is a Prism in Glasses?

Prism is triangular and made of plastic or glasses for the purpose of dispersing light into a spectrum or changing the direction in which light is reflected.

Prism lenses are special lenses that are prescribed by eye doctors and infused into regular lens prescriptions. The prism glasses do not include contain any focusing power, and therefore cannot any refractive errors. So, one of the most common uses for prism glasses is to correct diplopia or double vision. Double vision means someone sees two separate images of a single object. The prism glasses help to align the two images and correct the problem. The prism glasses can be used to improve binocular vision and reduce double vision, headaches, reading difficulties, and so on.


Why can't you wear expired contact lenses?

Contact lenses have a throwaway cycle. If the contact lens has been opened, the shelf life of the contact lens is calculated from the day it was opened. Contact lenses have a life cycle. The life cycle is the shelf life of contact lenses. For example, if you wear daily contact lenses, you will have to throw them away. If you wear monthly contact lenses, they will have a shelf life of one month. Even if you wear them only a few times, you will still have to throw them away. The shelf life of contact lenses is calculated from the day the lenses are taken apart, not from the number of days they have been worn.

After the shelf life of contact lenses, there will be some cases like lens aging, hardening, lens discoloration, decreased transparency, lens deformation, thickening, an increase of lens protein, and other precipitates. The microbe is easy to deposit, resulting in poor oxygen permeability. If you continue to wear it, it is easy to cause inflammation of the conjunctiva and corneal hypoxia, and the comfort level will be much worse. It is suggested to analyze the case according to your own care. Once the contact lenses have the above cases, they should be replaced in time.



About industrial pure titanium

For the industrial pure titanium, titanium content is not less than 98%, containing a small amount of oxygen, nitrogen, hydrogen, carbon, silicon, and iron impurities such as dense metal. The labels are TA1,TA2,TA3,TA4. It's arranged by more and more impurities. The TA1 titanium content is more than 99.5%, and the price is not high. But no matter which links, for molding, welding, polishing, processing difficulty is very great.The price of almost all titanium alloys in the national standard is higher than that of pure titanium.

In reality, the price of β titanium is higher than pure titanium. Pure titanium is almost no elastic, but β titanium is not only elastic, and has the advantages of ultra-light corrosion resistance. β titanium does not have a specific composition. Memory titanium can cost tens or even tens of times as much as pure titanium.

Using memory alloy to make glasses frame is the use of its superelastic characteristics at a certain temperature (elasticity is several times that of stainless steel) and did not use its memory function. Compared to beta-titanium, memory titanium is so difficult to process. It is so elastic that shaping is difficult and impossible at room temperature, and memory titanium heat treatment is another difficult and even secret process.
