Consider the elements of frame comfort.

What we need to know is that the frame exists first as a positioning device for the lens, and secondly as a beauty. The pupil is consistent with the optical center of the lens, so it should not be too high or too low. The horizontal direction is not skewed, and there is no one high and one low phenomenon. Bilateral symmetry is a standard for manufacturing enterprises. Non-mechanical symmetry is for the wearer. The frame should be adjusted according to the size of the wearer's face. The frame is not easy to slide down, and frequent slide is prone to the phenomenon that the pupil is too high and low to match the face.


Advantages of aspheric lenses

In reality, aspheric lenses were originally born to improve the marginalized optical properties of spherical lenses. The aspheric lens with special coating treatment has perfect visual performance, with a clearer, more comfortable visual effect. You can hardly feel the presence of aspheric lenses when you put them on. So you can enjoy the ease brought by aspheric lenses. They are more natural and more realistic, having less visual distortion. The aspheric lens can be designed with a flatter base arc, which not only makes the appearance beautiful but reduces the peripheral magnification so that when others look at the eyes of the people who wear glasses, the size will not change much.



The quality of the eyeglasses chain stores is relatively stable and reliable.

As the eyewear chain enterprises spread across the whole city or across regions, they occupy a large share of the local market, and the resulting scale effect reduces their own procurement costs and greatly enhances the awareness of brand quality. Therefore, the procurement of eyewear products is critical. Those defective products are much less likely to appear in these chain optician stores, which naturally ensures that overall product quality improves.


Titanium is currently too expensive to refine.

It is highly demanding in buckling, stamping, cutting, and welding. The extraction of titanium, like that of aluminum before the 19th century, was quite costly and produced in limited quantities, so it was used only in extremely important fields, such as aerospace, electronics, precision instrument manufacturing, and so on.



What Are Trivex Lenses?

What is Trivex? Trivex lenses were first produced in 2001. Trivex lenses come with several features such as light, impact-resistance, and high-performance strength. Recently, the use of Trivex as ophthalmic lens material has grown in popularity. Lenses made from Trivex material fulfill the same safety standards as those made from polycarbonate.

In addition, because of Trivex’s manufacturing process, plastic lenses sporting Trivex material do not distort vision as much. Trivex lenses offer 100 percent protection from UAV and UAB rays, sharper central vision, and sharper peripheral vision. Trivex was developed for military applications, so it is good for outdoor use. Other benefits include resistance to chemicals and better light refraction.

So, in the following section, we will show you the advantages and disadvantages of the Trivex lenses.


Oval frame

Soft and smooth lines, implicit and introverted, reflect the gentle and quiet fair maiden style. It seems that the first pair of glasses worn by everyone who is nearsighted is oval, basically in high school. It seems to have a student era of green implicit, quiet lady. Even in middle age, there are a lot of people who will choose a lot of beautiful styles of oval frames. It seems that in their hearts, they all want to stay young forever.



The shape of the lens is also important.

Aviator and cat-eye glasses should be avoided, as both will cut off the base of the prescription, resulting in poor reading vision. Instead, they should opt for shorter frames with rounded edges, such as bull horn frames, vintage wingtips, round frames, and oval frames.
