Consumers should choose different styles of frames according to their age and professional characteristics. Because everyone has different face shapes, different interpupillary distances, and different diopters, the size of the frames should vary from person to person.

Lenses are divided into glass lens, resin lens, and PC lens, and you can choose according to your preferences. The glass lens has a stable refractive index, good abrasion resistance, and stable optical performance, but it is relatively heavy and easy to break. Resin lens with high light transmittance is light, safe, and not easy to break, but the surface is easy to wear. PC lens has a high refractive index, but the surface is easy to wear.


Types of Progressive Lenses

At the same time, there are different types of progressive lenses and they are standard PALs, short corridor PALs, computer PALs, and Reading PALs.

Standard PALs must fit your vision needs. They can be added to frames of your choice, but you need to ensure that the frames are the right width and height proportions to grant enough space for the gradient changes in the lens.

Short corridor PALs are made to fit into smaller frames so as to suit a wider range of eyewear styles.

Computer PALs are designed for computer users and other occupations that require strong intermediate and distance vision.

Reading PALs are designed for those who enjoy reading and they can opt for a pair of lenses with a larger close vision zone.

Sales points of note for color changing lens

The discoloration rate of the lens is related to the intensity of ultraviolet light. The stronger the ultraviolet light is, the faster the discoloration rate will be, while the vice versa. The degree of discoloration is related to the ambient temperature. The higher the temperature is, the color of the lens is slightly lighter. Otherwise, the color is slightly darker. With the progress of manufacturing technology, the discoloration rate, especially the fading rate of the discoloration lens has been greatly improved, and the interference of temperature on the color depth is becoming less and less. Either glass or resin lenses react only with ultraviolet light, not visible light, so in some environments, they do not darken.



Benefits of glasses

You don't need a special cleaning plan, and they don't require much care. You can choose from a variety of frames to suit your style. If your vision stays the same, you won't need to change your glasses as often. You don't need to touch your eyes to wear them, and in addition, glasses can adjust the amount of light entering your eyes for optimal comfort and vision. Glasses are more powerful modifiers than contact lenses. Glasses are not only used as a tool to correct vision but as accessories. On different occasions, the different dresses should match different frame glasses, reflecting the person's different temperament.


The main parts of glasses

1. Spectacle lenses

One of the most important accessories for glasses is spectacle lenses. Due to the increase in myopia patients, the demand for spectacle lenses is also very large, but the prices of spectacles on the market are also uneven. To know whether the spectacle lens is good or not, you can't just look at the price of the product, but learn more about the value of the lens itself. For example, the resin lens is lighter and suitable for patients who wear it for a long time. The quality of the optical glass lens is better, and it is not easy to break, suitable for some elderly people.

The quality of spectacle lenses is also a key consideration. The market generally classifies lenses based on their structure, materials, and usefulness. The information on spectacle lenses is mostly chemical substances. It is very beneficial for us to select some good-quality lens materials. It is not only necessary to consider the function of the lens, but also to consider whether the lens material is harmful to the human body. Generally, the crystal stone materials are very safe and reliable, and we can choose carefully.

2. Spectacle frame

Another important figure in eyeglasses accessories is the frame. For those who like lightweight glasses, it is more appropriate to choose ultra-light frames or half frames. However, the frame must have durable and play a good role in maintaining the lens, otherwise, it will lose the meaning of the frame. Of course, the temples are also a part of the frame. There are also nose pads for glasses accessories. Many people have more requirements for nose pads. Generally, they choose soft ones that are not easy to press on the bridge of the nose.

Different styles of glasses

If the style of new glasses is different from the old glasses, the angles of the glasses are also different. So the new glasses will cause visual differences. The symptoms of dizziness after wearing the new glasses will occur after a short period of time. If you adapt, you should be able to return to normal.

In order to avoid discomfort in wearing glasses due to inaccurate optometry, experts suggest that myopia should choose a professional eye hospital for medical optometry. When the glasses are damaged, they should be replaced in time to avoid injury to the eyes.
