Open your eyes to welcome a new day! Eyes are also called "windows to the soul", because before we have the ability to speak, the "eyes" allow us to learn and understand the world, and to directly feel or express our emotions. However, have you ever had a good understanding of these "eyes" that accompany us all our lives? Exploring a visual journey, starting with the construction of the eye Source: Wikipedia The overall structure of the eye is extremely precise and can be mainly divided into five parts: the eyeball, the eyelid, the lacrimal organ, the eye socket and the eye muscle. Among them, "eyeball" is the most important medium for visual transmission. If you want to understand the formation of vision, start here. According to the definition of Wikipedia : The eye (also known as the eye, the eye, and the trick) is the organ of vision that senses light and converts it into electrochemical pulses in the nerves. The more complex eye is an optical system that collects light from the surrounding environment, adjusts the intensity of the light entering the eye through the iris, uses an adjustable lens to focus, and projects an image to the light-sensitive retina, converting the number list image into an electrical signal. , transmitted through the optic nerve to the visual system and other parts of the brain. Do you find it too complicated to understand? So let's imagine the eye as a camera now, and you should know better. What we see in front of us is the lens that enters the camera through the "cornea", and the light that enters is controlled by the aperture "pupil"; and the "crystal" is the focusing device that refracts light to make the image clearer; finally, All images will be projected on the negative "retina". Very smart and amazing organ design! However, after admiring the structure of vision, you must also understand that not every pair of eyes is smooth. In the 21st century, "myopia", the most common civilization disease of modern people. Is because the light cannot be accurately focused on the retina after entering the eye, making the distant image blurry. In addition, the eyeball crisis lurking in our daily habits is not just myopia... 3C does not leave your hand, aging eyes report early Common eye problems include myopia, presbyopia, dry eye, cataract, glaucoma, macular degeneration and retinal detachment, etc. In addition to the natural aging of the eyes, the concurrent causes of these eye diseases are also closely related to personal daily habits. According to statistics, the age of onset of glaucoma and macular degeneration, which used to be dominated by silver-haired people, has advanced to middle age. This change is mainly because with the development of technology, people stare at the screen almost all day long, and life is inseparable from 3C products. In this case, even if I often hear that blue light is harmful to the eyes, it still cannot reduce the use time. But is it that we can only let the aging crisis of the eyes accompany.
