Can you look at your phone while wearing polarized sunglasses?
That's because polarized lenses filter the light from some phones, leaving only black stripes visible.Polarized sunglasses have polarized lenses, and cell phone screens have polarized patches in their components. The polarized film has the function of shielding and passing through the incident light, which can make the longitudinal light or transverse light one kind of passing through, one kind of obscured. Because different phones have different polaroid settings, there will be different shades at different viewing angles. Thanks to a combination of polarizing lenses and lenses, both of which filter the direction of light, the screen can't be seen when the shielding and penetrating parts overlap.
What are pure titanium rimless glasses?
Pure titanium rimless glasses combine the advantages of pure titanium glasses with rimless glasses. Rimless frames are mainly focused on lightweight, reducing the pressure on the wearer and enhancing comfort.

Glasses Size - Bridge Width
The bridge width is the distance between two lenses, measured from the innermost layer of each lens. Finding the right bridge width will allow your sunglasses or glasses to be put properly on the bridge of your nose. The bridge of the nose is an essential element because even though the frame looks pretty attractive, it helps people see more clearly. The precise distance between the two lenses helps reduce the pressure on the eye, helping the nose, without putting too much pressure on the inside of the eye. The size of the eye and the size of the bridge is usually adjacent, sometimes separated by a square icon.

Types of Varifocal Lenses
As is well known, there are several types of varifocal lenses. So, in this section, we will list some the types of varifocal lenses.
Standard varifocal lens: standard varifocal lenses are the entry-level varifocal options and are chosen as an enhanced alternative to bifocals. They have clear and fairly wide focal areas for distance, reading, and in between.
Premium varifocal lens: premium varifocal lenses are also called free form varifocals or back surfaced digital varifocal lenses. It offers much clearer vision at all points and is a significant step up from a standard varifocal lens in terms of vision, clarity, focus, and ease of adapting to them. They are created using the latest computer-driven equipment and have a wider field of vision at the distance, intermediate/in-between, and reading focal points.
What are acetate glasses?
Acetate spectacle frames are the most common spectacle frames on the market. It has a light texture and good gloss, which is very popular among young men and women. Acetate frames are lighter and generally considered to be better than plastic frames. Acetate fiberboard is known for its Hypo-Allergenic, so it is a popular choice for people with sensitive skin. Unlike some plastic or metal frames, they can cause allergic reactions. However, you will find that acetate frames are usually more expensive than ordinary plastic frames. So what is the reason?
Acetate is one of the first synthetic fibers. It was not used to make glasses until the late 1940s. The higher the quality of acetate, the better the gloss and transparency. Not easy to burn is one of the biggest characteristics of acetate fiber. Also because of the non-combustibility of acetate fiber, this material can hardly be affected by ultraviolet radiation to change color, and can better maintain the gloss of the spectacle frame. Moreover, it is light and hard, and it is not easy to deform.
