Plate Frame

Glasses processed with acetate sheets become sheet frames. The plate frame is not easy to burn, the specific gravity is small, and the base arc is not irradiated by ultraviolet rays to change color. In addition, it has high hardness, good gloss, and durability, but it is not easy to bake and the temperature is 115-130 degrees. The style is more beautiful, and it is not easy to deform after wearing. The current market is that the plate frame combines the thickness of the plate and the metal texture, and combines different types of lenses to create fashion and personality. There are not only retro-style frames, but also popular frames, combining a variety of elements to create classic glasses frames. Its workmanship has undergone complex processes such as turning, grinding, and polishing, so it is relatively high-end.


What is an aspheric lens?

Strictly speaking, any lens with a refractive surface that is not a sphere is an aspheric lens, including ordinary astigmatism lens, progressive multi-focal lens, Aspheric apical lens, etc. But customarily, our daily aspheric lens refers to the Aspheric apical lens. From the center of the lens to the periphery, the radius of curvature increases (the surface of the lens flattens out).



Confirm the optometric data

It is necessary to confirm the accuracy of optometric data. If you stay up late or look at the phone or computer for too long before the optometry, leading to visual fatigue, it will increase the degree. But if you can let your eyes have a good rest, and then take optometry, the degree may be restored to the original situation, so you need to know the state of optometry, to check if it really had increased in degrees. The main purpose of progressive lens is to use it for people who have bleached eyes and often take off the lens.


The Advantages of Polycarbonate Glasses

In fact, polycarbonate glasses come with several benefits and this section will show some of them.

First, polycarbonate glasses are safe and are virtually unbreakable. A study found that polycarbonate glasses were more impact-resistance than glasses or other types of plastic lenses.

Second, polycarbonate glasses are thinner than other types of lenses. This feature makes them ideal for people who have strong prescriptions. Lighter and thinner eyeglasses are less likely to slip off your nose and are more comfortable for everyday wear.

Third, extended exposure to UV radiation from the sun can cause damage to your eyes and lead to some eye conditions such as cataracts or macular degeneration. Of course, polycarbonate glasses can block out harmful UV rays from the sun and provide good protection for your eyes.

However, there are some negative voices of polycarbonate lenses.



The Advantages of Trifocal Lenses

The greatest advantage of trifocal lenses is that they have three prescriptions in one, which means that not only do you not have to buy three separate pairs of glasses, but you also won’t have to constantly change them as you go about your day.

Another advantage of trifocal lenses is that in some cases, they offer a broader viewing area for near and intermediate-distance applications like reading and using the computer.


Defects of Adolescent Progressive Lenses

Long-term use of progressive lenses will cause a deficiency of binocular physiological regulation in adolescents. Long-term use of progressive lens may lead to ocular muscle imbalance in both eyes of adolescents. After wearing a progressive lens, part of the field of vision is not clear, which will affect the activities of young people. After wearing the progressive lens, when walking downstairs, riding a bicycle, and doing various sports, you need to see through the near area under the lens to see far, which will affect your activities due to blurring. It is not comfortable to wear a progressive lens to look at an upright screen such as a computer, and the refractive power of a progressive lens in these parts is different. To see the screen clearly, it is necessary to adjust repeatedly, which is easy to cause adjustment disorders and visual fatigue, even dizziness, and eye pain.



What Are the Advantages of High-Index Lenses?

In this section, we will show you the advantages of high-index lenses.

  1. Thanks to the slim shape and narrow edges, high index lenses offer wearers the flexibility to choose from a wide array of fashion-forward frames. Their size means that they can be easily paired with sleek metal frames or incorporated into rimless eyewear for an attractive barely-there look.
  2. High index lenses are more comfortable for extended use because they are lighter than the traditional counterparts.
  3. High index lenses are available with many of the same options as traditional lenses. For example, they can be either single-vision or progressive.
  4. For users with strong prescriptions, high index lenses mean no bulky, bottle-glasses appearance. This can reduce the unwanted bug-eye look traditionally associated with very thick lenses.

However, there are some negative voices of high index lenses.
