What are the functions of anti-blue glasses?
The myopia of young people is getting worse every year, and the main factor that causes myopia in young people is the high-energy blue light of mobile phones and computers. Children’s lenses are clearer and more transparent than adults and have a weaker effect of blocking and filtering the blue light of electronic products. The blue light transmittance of their lenses is several times higher than that of adults so there is more blue light penetrates the lens to reach the retina. Therefore, the damage caused by blue light to children's eyes is much more serious than that of adults. Naturally, be careful with blue light. When the child is facing the screen of the mobile phone and computer, wearing anti-blue glasses can more or less reduce the blue light and reduce the blue light energy. The blue light energy that enters the retina is not so much so strong, and naturally, it will not damage the pigment epithelial cells and photoreceptor cells on the retina, thus protecting the child's eyes.
The main function of anti-blue glasses is to relieve eye fatigue, reduce retinal damage, prevent myopia from deepening, and reduce the incidence of special eye diseases such as macular degeneration and cataracts. According to your own situation, if you are really looking at the phone and computer screen for a long time, wearing anti-blue glasses is better. Usually, pay more attention to the habit of using your eyes, rest your eyes appropriately, and play less with mobile phones and computers.

Prism is triangular and made of plastic or glasses for the purpose of dispersing light into a spectrum or changing the direction in which light is reflected.
Prism lenses are special lenses that are prescribed by eye doctors and infused into regular lens prescriptions. The prism glasses do not include contain any focusing power, and therefore cannot any refractive errors. So, one of the most common uses for prism glasses is to correct diplopia or double vision. Double vision means someone sees two separate images of a single object. The prism glasses help to align the two images and correct the problem. The prism glasses can be used to improve binocular vision and reduce double vision, headaches, reading difficulties, and so on.
Disadvantages of progressive lenses
Wearing progressive multifocal glasses for the first time may cause slight dizziness and shaking when walking. Be careful when moving up the stairs. The perception of space changes, the perception of the distance of the object, and the perception of depth have changed. New wearers should not drive immediately and do vigorous exercise. When you look close, you need to turn your eyes down, and your eyes are mildly uncomfortable. Seeing the object through the blurred vision area around the lens, the object becomes blurred. Therefore, when new wearers look at things, turn their heads more, turn their eyes less, try to use the far-distance zone, the near-distance zone, and the middle-distance zone to see the object.

It is necessary to apply practical artistic aesthetics to the decoration design of physical eyewear stores, product packaging, and marketing planning, to increase customers' experience of the store, increase store goodwill, brand memory, interest in the product, and stimulating customers' consumption.
