If you lie down in the dark and use your smartphone, you may go blind...

The optic nerve and nerve fiber layers play an important role in transmitting visual information received from the eye to the brain. Glaucoma, along with cataracts and diabetic retinopathy, is a large part of blindness.
Glaucoma is a disease that can occur from children to the elderly, but it is known to be more common in old age, has high myopia, has glaucoma in the family, has injured the eye in the past, has long-term steroid eye drops, and has diabetes and arteriosclerosis.
As the outlet of the waterproof outlet is suddenly blocked, the intraocular pressure increases rapidly, and symptoms such as severe ocular pain, congestion, decreased vision due to corneal swelling, and headaches occur. It is a disease that often visits the emergency room due to clear symptoms. It is a disease that must be suspected if sudden eye pain occurs in the elderly and one head is severely sick because it often occurs as they get older.
Eye pain, headaches, nausea, and vomiting appear, so people who have never experienced eye pain are likely to mistake it for headaches. That's why people confuse brain lesions and symptoms. It is because of these clinical symptoms that patients with obstructive glaucoma seek ophthalmology after tests such as brain CT. Therefore, acute obstructive glaucoma should be suspected if it is accompanied by a headache, decreased vision, and ocular congestion.
Such paroxysmal pain is likely to be triggered when working for a long time and close range in a dark space. In particular, it is known that the incidence rate increases due to the prolonged period of indoor activity in winter. If the front angle is narrow, the risk increases if you use your smartphone in a prone position indoors with the lights off for a long time. If you look at your smartphone in the dark for a long time, the lens thickens to control the short distance, and the pupil grows, blocking the waterproof outlet, causing the intraocular pressure to suddenly rise.
Also, if I use my smartphone in a dark space, I blink less without realizing it. Eye fatigue also increases, which can lead to symptoms of vision disorders such as light blur, glare, and night vision. If the ciliate muscles in the eye continue to be tense to focus, eye fatigue increases, which can cause temporary blurred vision or objects to overlap in two.
Acute obstructive angle glaucoma is a disease that can lead to blindness, but it can be prevented through regular ophthalmic examinations. If the anterior angle is narrow, the right smartphone usage habit should be used to prevent an increase in intraocular pressure, and if symptoms appear, visit an ophthalmologist quickly for appropriate treatment.
Park Sung-eun, head of the ophthalmology center at Seran Hospital, said, `If you look at a bright smartphone in the dark for a long time, eye fatigue increases, and those with a narrow front face a risk of developing a 'acute obstructive angle attack'.'"If these people lie on their stomachs in the dark and look at their smartphones, the angle of the front decreases." This can cause an angle of closure, which can lead to a sharp rise in intraocular pressure," he stressed.
Manager Park Sung-eun said, "When using a smartphone, it is better to look at it in a bright place rather than in a dark place and in a static position rather than on your stomach. When acute obstructive angle glaucoma occurs, intraocular pressure should be reduced as the top priority, and a bypass path that can be discharged waterproof instead of anterior angle through laser iris incision, or a cataract surgery should be used to deepen the anterior angle."," he said.
