The difference between wearing glasses and not wearing glasses is this. First of all, if your eyes are diseased, you must wear glasses to correct your vision. If you don't wear glasses, the image will not fall on the retina, so you will not be able to see clearly.
People often wear glasses, which are a kind of vision correction thing. Glasses are lenses embedded in frames and worn in front of the eyes to improve vision, protect the eyes or for decorative purposes. It can correct a variety of power problems, including myopia, hyperopia, astigmatism, presbyopia or strabismus, amblyopia, etc.
In most cases, people wear glasses for myopia. Many people use their eyes for short-sightedness, which is unhygienic. They do homework or see things for a long time, and their eyes cannot be corrected over time. , then such problems will occur if rest is not improved. Regardless of performance or near parallel light entering the eye, it will pass through the eye's refractive system and focus on the retina, where it will present a clear image, allowing people to see objects clearly and facilitate life activities. However, if parallel light enters the eye and cannot be focused on the retina through the refractive system of the eye, or is focused in front of the retina, objects cannot be seen clearly after focusing on the retina, affecting normal quality of life. Myopia refers to the absence of any adjustment. The refractive state is limited to more than 5 meters, and the refractive system of the eye is focused in front of the retina. The eye with this refractive state is called myopia. When looking at people, the image formed on the retina is blurry, but close objects are still clear.
If the eyes are farsighted, then such problems will occur. As for eye diseases, such malfunctions will occur. Under normal circumstances, when a person is at rest, if parallel light enters the eye, it will pass through the bend of the eye. The light system focuses on the retina and presents a clear image on the retina. People can see objects clearly and facilitate life activities. If parallel light rays enter the eye, and the eye struck by the parallel light ray is placed behind the retina, hyperopia will result. Another situation is that the front-to-back diameter of the eye is relatively small, so the image will be behind the retina. In order for the light system to focus on the retina, if it is focused in front of the retina or on the retina, it will not fall on the retina, causing errors and unclearness, so in this case, you must wear glasses.
After wearing glasses, many people will see things very clearly and clearly. When you don't wear glasses, you can't see clearly. In fact, sometimes the glasses made by people nowadays are very good. Wearing glasses will make your eyes clearer. His eye signature will have a lot of anti-reflection coating to make the light clearer when it comes in.
