Red and blue glasses, shutter glassesRed and blue glasses and shutter glasses were two different 3D glasses technologies.
The red and blue glasses were complementary color glasses. They were a relatively cheap 3D display technology that did not require any equipment and were cheap. It mainly appeared in red, blue, red, green, and other modes. The color separation method would specially print two different colors. Through the matching red and blue glasses, only the red image could be seen under the red lens, and the blue lens could only see the blue image. The different images seen by the two eyes overlapped in the brain to present a 3D effect. However, the 3D image seen in this way had no color to speak of and would have double images, which would easily make the eyes tired and dizzy.
Shutter glasses were active shutter 3D glasses. Compared to red and blue glasses, they had many advantages, such as less color distortion, less loss of resolution, and less loss of brightness. It could maintain the original resolution of the picture and achieve a true full HD 3D effect without causing the brightness of the picture to decrease. The 3D effect was realistic and the viewing angle was wide. However, it was more expensive and inconvenient to carry. It also required the left and right eyes to receive images with a frequency of more than 60 Hertz.

Which is better, multifocal glasses or defocused glasses?There was a certain relationship between multifocal glasses and defocused glasses. Multifocal defocused glasses were a type of defocused glasses.
Defocal glasses (including multifocal lenses) were frame lenses designed using the principle of central and peripheral myopia-defocal lenses. The principle was to form a focused image and a mythic defocus image in the eye, and use the defocus image to interfere with the growth of the eye axis and delay the progression of myobia. This was one of the methods that had been proven to be effective in interfering with the progression of myobia.
Traditional single-focal glasses were mainly used to correct vision and had no effect on peripheral defocus. They could not control the development of nearsightedness well. Defocal glasses had a better effect in controlling the progression of short-sightedness. If the multifocal glasses referred to multifocal lenses, then it had positive significance in the prevention and control of nearsightedness. However, if it was traditional multifocal glasses (designed without defocusing), it might not be as good as defocusing glasses in controlling the development of nearsightedness.
In short, if one were to focus on the prevention and control of nearsightedness, the defocused glasses (including the type of multifocal defocused glasses) had more advantages than the traditional non-defocused multifocal glasses.
Raise the curtainThe action of "lifting the curtain" had different meanings in different situations. In literary works such as " Water Margins," there was a description of " lifting the curtain " to enter the hall. In some modern scenarios, such as the curtains in the first-class cabin of a plane were drawn to carry out cabin service and separate the cabin to prevent economy class passengers from asking for the same service after seeing it. The female principal of the school said that she would lift the toilet curtain to catch smoking students, which was a management method. In the Uniqlo fitting room incident, the man lifted the fitting room curtain and caused controversy.

Glasses are really versatile. First, you can have glasses-wearing girls take them off and suddenly become beautiful, or have girls wearing glasses flashing those cute grins, or have girls stealing the protagonist's glasses and putting them on like, "Haha, got your glasses!" That's just way too cute! Also, boys with glasses! I really like when their glasses have that suspicious looking gleam, and it's amazing how it can look really cool or just be a joke. I really like how it can fulfill all those abstract needs. Being able to switch up the styles and colors of glasses based on your mood is a lot of fun too! It's actually so much fun! You have those half rim glasses, or the thick frame glasses, everything! It's like you're enjoying all these kinds of glasses at a buffet. I really want Luna to try some on or Marine to try some on to replace her eyepatch. We really need glasses to become a thing in hololive and start selling them for HoloComi. Don't. You. Think. We. Really. Need. To. Officially. Give. Everyone. Glasses?
