It can effectively prevent the damage to the eyes and face caused by the friction of the broken lens frame during use. Because of its specific molecular structure, the chemical resistance is good.

The little screws inside, about four of them (hinges and nose pad), are important.Silk screen printing or laser engraving refers to the above logo or data, some of the silk screen, easy to sweat and fade, does not affect the use.

Disadvantages of Progressive Lens

There are deformation areas under the left and right sides of the lens, which make the image blurry and irregular. It takes 1-3 weeks to get used to it. In addition, it has a narrower field of view in the near and middle distances, and long-term concentration on the narrow focal point can easily make the eyes tired. Suitable for people who need to alternate between distant, medium, and near vision.

However, with the development of science and technology, more and more progressive multifocal glasses have emerged that have a wider field of view, more comfortable wearing, and better meet the needs of eyes. Nowadays, the use rate of progressive lenses among middle-aged and elderly people abroad is quite high. Single-lens and double-lens reading glasses are gradually being replaced by progressive multifocal glasses.

It can be identified in the light. Ordinary lenses have a yellowish feeling under the reflection of light, while the anti-blue lens film color has blue on the yellow-green film, which is the cause of reflecting blue light out. Check the instruction manual to verify that the lenses contain radiation-resistant materials. When wearing, you can look at the electronic screen far away, and check if there is a sense of irritation to the eyes. The biggest difference between the regular lens and the anti-blue lens is the coating layer. If you look carefully, you can see that the anti-blue lens layer is very clear. Put the anti-blue light glasses on the fully open phone screen and observe if the covered area is blue. If it is, the prevention effect is good. This is because the blue light emitted by the phone is reflected on the phone screen by the lens.

Should I wear glasses all the time for myopia?

Whether it is false myopia or true myopia, as long as a pair of suitable myopia glasses are used to complement the missing refractive power of the lens, the image of the object can fall on the retina again, and the distant objects can be seen again. Adolescents usually use high eye intensity and often wear myopia glasses, so that the ciliary muscles do not need to be 'so tired' to adjust, which can avoid further aggravation of pseudomyopia. However, adolescents are still in the process of development, and the degree of true myopia will gradually increase with age. Therefore, as the degree of myopia develops, refraction should be performed at regular intervals, and appropriate glasses for myopia can be prepared to prevent false myopia.

For adults under 200 degrees, because the degree is relatively light, they can wear glasses when they are looking at the distance and not wear glasses when they are near, which has little effect on vision. But for adults with high myopia, because of the weak adjustment ability of the eyes, it is recommended to wear glasses regardless of near vision or distance vision.

In summary, wearing myopia glasses is to reduce eye fatigue and prevents the occurrence of false myopia. Wearing myopia glasses from time to time may aggravate the degree of myopia, and wearing them often does not cause a burden on the eyes. Therefore, for myopia glasses, wearing them frequently is the most correct way to wear them.
