With the rapid changes in economy and technology, more and more young people are active in all walks of life in the field of computer applications. Long time and high intensity eye use, coupled with bad eye habits such as playing games, brushing WeChat, and catching up with dramas, have led to more and more eye discomfort, ranging from lacrimation, dryness, and vision loss in mild cases to fundus lesions and even blindness in severe cases. Retinal detachment Retinal detachment is mainly caused by high myopia over 600 degrees and trauma, collision in sports, etc. However, there are some patients who do not have the above-mentioned triggers, but mainly due to prolonged overuse of the eyes making the barrier function of the eyes diminished resulting in retinal detachment. If you feel a sudden increase of black shadows like flying mosquitoes in front of your eyes, or a flashing light similar to a flashing light often appears in the corner of your eyes, or like a black curtain is covering you, and the black curtain area is getting bigger and bigger, it may be a precursor of retinal detachment. Retinal dry eye syndrome Dry eye syndrome, many people do not treat it as a disease, the emergence of easy fatigue, itchy eyes, fear of wind, photophobia symptoms also did not care, dry eye syndrome is another manifestation of foreign body sensation, painful burning sensation, secretions sticky, sensitive to external stimuli; sometimes the eyes are too dry, the basic tear deficiency, but to stimulate reflex tear secretion, and often caused by tears; more serious eyes will be red, swollen, congested, keratinized, and In more serious cases, the eyes will be red, congested, keratinized, and the corneal epithelium will break down and have filamentous adhesions, which can cause keratoconjunctival lesions over time and can affect vision. If dry eye is left unattended, it will become more and more serious, and cases of blindness in patients with severe dry eye are encountered in clinical practice. Transient dark haze Occasionally, transient dark haze occurs in night shift workers and people who stay up late continuously, and refers to a condition in which the scene seen by the eyes suddenly becomes so dark that they cannot see anything, and the eyes return to normal after a short period of time. This condition occurs, in addition to proper rest, but also pay attention to the prevention of cardiovascular and cerebrovascular disease to prevent accidents. The two main culprits of eye disease attacks in young and middle-aged groups are computers and staying up late. The eyes, like the body, should not be used excessively, otherwise the fundus will bleed, congestion, or lead to the occurrence of optic neuritis. Moreover, the eyes are more fragile than the body, and once the body’s immunity is reduced, lesions may manifest from the eyes. So, how to prevent “eye overuse”? 1, if you use a computer or cell phone, it is best to reduce the brightness of the screen to the extent that it is not blinding, while reducing the indoor light to avoid direct light on the screen and interference; 2, pay attention to moisturizing the eyes, in addition to blinking more, you can also drop some eye drops with the same composition of our tears, such as artificial tears; 3, pay attention to regular rest, the eyes should not work too long, look at the computer or cell phone for 30 minutes Be sure to shift your eyes to look away or do eye exercises. A lifetime, 80% of the information from the eyes, the lack of vision, will seriously affect the quality of life, some people may think that eye problems often appear in the elderly and children, young people are in the “safe zone”, but with the onset of eye disease younger, young people are also experiencing the “eye crisis” can not be ignored. However, with the younger onset of eye diseases, young and middle-aged people are experiencing an “eye crisis” that cannot be ignored. The eyes are an important organ for perceiving light, so if young and middle-aged people have not had an eye examination before, it is necessary to go to a regular eye hospital to make a comprehensive examination and early screening with the help of examining glasses, slit lamps and other instruments, so as not to miss the best time to treat eye diseases.
